The
Independent August 21, 2005: Migratory ducks and waders could
bring bird flu to Britain this winter, experts have warned, after the
disease was found in wild flocks in Russia. The potentially lethal avian flu
virus, H5N1, is now spreading westwards after health experts in Siberia and
Kazakhstan discovered outbreaks of the virus in birds that will soon enter
Europe. Yesterday, as the total number of confirmed cases in Russia hit 40, the
authorities revealed the first suspected case of the virus at a commercial
chicken farm in the western Siberian region of Omsk. Another 78 villages have
suspected cases. Although the chances of the virus spreading from birds to
humans within Britain is thought to be very low, the Cabinet's civil disasters
committee, Cobra, is to stage its own emergency exercise next month.

The Rome-Fiumicino international airport has
begun implementing precautionary measures involving passengers and merchandise
originating from regions affected by bird flu. Passengers traveling to the
Rome airport from China or Russia may be immediately hospitalized in an
infectious diseases clinic if they shows signs of respiratory problems,
airport authorities said Saturday.

August 18, 2005: The World Health Organization (WHO) has called on its
offices worldwide to stockpile drugs to protect at least one-third of staff and
their families from a potential bird flu pandemic. The call comes after
news that the bird flu virus H5N1 has spread from South-East Asia to Kazakhstan
and Russia. The WHO also advises their offices to stockpile medical equipment
such as syringes, antibiotics and face-masks, and is giving advice on how to
convert large areas, such as gymnasiums, into temporary wards.

August 13, 2005: Reports indicate H5N1 wild bird flu is expanding
dramatically in Novosibirsk
and points west along Russia's southern border (see map).
The leading edge of the advance now appears to be entering the province of
Chelyabinsk. The large number of additional points under suspicion
suggests that there are additional unreported locations in northern Kazakhstan
and the advance of the H5N1 has probably already entered European Russia. As
the weather cools more migration into Europe is expected.

August 12, 2005: GlaxoSmithKline Plc's Relenza may be as effective
as Roche Holding AG's Tamiflu in the treatment of bird flu, and should be
included in government stockpiles against the potentially fatal illness,
researchers said in this week's Lancet medical journal. Relenza, also known as
zanamivir, causes fewer adverse reactions than Tamiflu and has a favorable
resistance profile, according to Kenneth Tsang, a researcher at Queen Mary
Hospital in Hong Kong. Tsang's study showed both drugs have similar efficacy.

August 11, 2005: The report of 20 meningitis cases in and around
the village of Rybalovo in the Tomsk region is cause for concern. The
village is just northwest of Chany Lake in Novosibirsk where there have been at
least 14 outbreaks of H5N1 bird flu (see map).
Meningitis can also be due to secondary infections after the flu, so
testing of the meningitis patients ffor influenza A is warranted.
Canadian
Press 11, 2005: Enthusiasm over the news that U.S. researchers have
proven a vaccine is effective against the H5N1 avian flu strain was tempered
Monday with word that it took massive doses - roughly 12 times the normal amount
- to produce a protective response in humans. Given that manufacturers can only
make enough vaccine for a fraction of the world's population in normal times
with regular dosing schedules, experts said the findings underscore the urgent
need to find ways to produce the same response with smaller doses of vaccine.
"I think these results suggest the world is even less prepared than more
prepared," said Dr. Michael Osterholm, director of the Center for
Infectious Disease Research and Policy at the University of Minnesota. "And
unfortunately many policy makers might take this announcement as being 'We've
hit the gold mine' - when in fact I would suggest we are having a hard time even
finding water."

Online August 7, 2005: THE government is to mount an
exercise to help emergency services prepare for any potential bird flu pandemic
that could kill thousands of people in Britain. Sir
Liam Donaldson, the chief medical officer, has said that the question “is not
if the pandemic comes, but when”. The exercise in September — a table-top
simulation in a bunker beneath Whitehall — will be co-ordinated by Cobra, the
cabinet civil emergencies committee, and will involve the army, police, health
department and other key government organisations. According to the health
department’s contingency plan, the healthcare system could be overwhelmed.
Estimates of deaths in the first six weeks of the outbreak range from 20,000 up
to 710,000, after which the disease would begin to subside. About 20m people
could suffer serious breathing problems.

6, 2005: Preliminary human tests show an experimental vaccine made by
Sanofi-Aventis SA is effective against a bird flu virus feared capable of
starting a lethal worldwide outbreak of the disease, the National Institutes of
Health said. Results from 113 people showed that protective proteins,
called neutralizing antibodies, rose to an effective level after the shots, said
Anthony Fauci, director of the NIH's National Institute for Allergy and
Infectious Diseases. The full study will include results from more than 450
subjects, he said. An effective vaccine would provide a line of defense against
the threat of the H5N1 bird flu that has killed at least 57 people and millions
of birds in Asia. It might help health officials head off a repeat of the 1918
outbreak of deadly flu that may have killed as many as 50 million people
worldwide.

August 6 2005: An earlier human vaccine against A(H5N1) avian
influenza virus was prepared after it first appeared in the world, in Hong Kong
in 1997. That vaccine was never fully developed or used, and the strain has
mutated since then. In interviews over recent days, Dr. Fauci has said that
tests so far have shown that the new vaccine produced a strong immune response
among the small group of healthy adults under age 65 who volunteered to receive
it, although the doses needed were higher than in the standard influenza vaccine
offered each year. The above comments on the development of a pandemic
vaccine are overshadowed somewhat by the rapid spread
of H5N1 across Russia,
Kazakhstan,
and Mongolia.
Although the sequence of the rapidly spreading H5N1 has not been published, descriptions
of the sequence sound much like the recently published H5N1 sequences
from Qinghai Lake. Those sequences suggest that the current pandemic
vaccine being tested worldwide will not be effective against the H5N1 expected
to spread throughout Asia and Europe
in the upcoming weeks.

August 6, 2005: H5N1 bird flu has migrated to Mongolia. Mongolia's
proximity to Qinghai
Lake, Russia,
and Kazakhstan,
all of which have confirmed H5N1 bird flu, predicted that bird flu would also
reach Mongolia. Prior H5 isolates from Chnay Lake and Primorie had shown related
to each other as well as H5 in Europe, indicting migratory bird transmit H5 from
Chany
Lake to Primorie
or vice versa. Either direction however would likely include flights over Mongolia.
The H5N1 detected in China, Russia and Kazakhstan kills geese, which is unusual.
The dead geese in Mongolia strongly suggest that the H5N1 in the three adjacent
countries has migrated to Mongolia also. The dead geese in Mongolia also
suggest H5N1 will be detected in Primorie also. The appearance of the Asian
version of H5N1 has not been previously reported in Russia, Kazakhstan, or
Mongolia. Thus, H5N1 has expanded its geographical range as well as its
host range. After migrating from Russian and northern China, it seems
likely that most of Asia and Europe
will be H5N1 positive in the upcoming flu season in the northern hemisphere.

Online August 3, 2005: Scientists Warn Over Bird Flu Threat: Only decisive
action within days of the first human to human cases of avian flu could prevent
the triggering of a pandemic that would kill millions, scientists said
today. If the H5N1 virus currently circulating among birds in Asia evolves the
ability to pass easily from person to person, health authorities will have
just three weeks to contain it with drugs before it becomes a global threat,
according to two sophisticated computer models. Should this opportunity be
missed, the result could be a pandemic that infects half the world’s
population and kills even more than the 20 to 50 million who died in the
"Spanish flu" of 1918-19. Countries worldwide, including
Britain, would be powerless to protect themselves against the virus, though
judicious use of drugs and vaccination might reduce the death toll. The
findings, from two independent international research teams, show the urgency of
building up a "mobile stockpile" of three million courses of the
antiviral drug Tamiflu, that can be deployed anywhere in the world within three
days. The World Health Organisation has just 120,000. The models suggest that
swift preventive use of the drug to treat people who come into contact with sick
patients could contain an outbreak before it turns into a pandemic. They also
point to the importance of thorough disease surveillance in the Asian nations
in which a human H5N1 outbreak is most likely. If the first cases and
clusters are missed, vital time will be lost and containment efforts could
become futile. "Control of a human outbreak is potentially possible but
only when it is in its early stages," said Neil Ferguson, Professor of
Mathematical Biology at Imperial College, London, who led the first study.
"Once it is beyond this, once it reaches the UK, there is no chance of
stopping it, only of mitigating its impact. We need to act quickly, detect cases
quickly and treat people quickly. The challenges are great but the potential
benefits are saving millions of lives. "This is our only option for
making a big difference to a pandemic outcome. If we let it spread we’ll
at best be able to prevent the deaths of perhaps half those infected in the
UK." Ira Longini, Professor of Biostatistics at Emory University in Atlanta
and the leader of the second team, said: "If detection and containment
starts within three weeks or so, we have a good chance. Once the response takes
more than a month there is a very poor chance of containment." Both teams
said the World Health Organisation (WHO) should buy three million doses of
Tamiflu, which could be sent within three days to contain an outbreak anywhere
in the world. WHO is currently negotiating over a large stockpile with the
manufacturers, Roche, which is understood to be considering donating the drugs.
While there is an experimental vaccine against H5N1, a pandemic strain is likely
to be genetically different from the present one, making it less effective.
Tamiflu is considered the best option, as it can be used prophylactically to
prevent infection.

August 3, 2005: Rapid quarantines, travel restrictions and plenty of
medicine quickly distributed could prevent millions of deaths in a bird flu
outbreak in Southeast Asia, public health scientists said in a pair of studies
examining the threat. Such an emergency plan would have to be enacted
within two days and the spread of the virus limited to a few dozen cases – a
challenge for an area where communications are often rudimentary and entire
economies and transportation networks could be disrupted. "Containment is
challenging," said Neil Ferguson of Imperial College in London and lead
author of one of the two studies examining avian flu control measures. "We
just can't cherry-pick the more easily implemented solutions." Once the
virus spreads to mobile, urban nations like the United States or Great Britain,
"chances of stamping out the pandemic are poor," he said in a news
conference Wednesday.
The
Register August 3, 2005: Russia's Emergencies Ministry is warning that the
H5N1 strain of the bird-flu virus, the strain dangerous to humans and
responsible for the deaths of more than 50 people in Asia, could spread into
mainland Europe from farms in Siberia. The Ministry issued a statement
saying that the autumnal migration of birds from Siberia to the Caspian and
Black Sea regions could increase the risk of new outbreaks, Reuters reports.
"Human infection, especially among workers at poultry farms, cannot be
ruled out," the statement warned. In the Novosibirsk region, where the
virus has claimed nearly 3,000 head of domestic poultry, farmers have already
begun slaughtering birds - a program that could last for at least a week, or
even for 10 days. The H5N1 strain of the bird-flu virus can be passed from bird
to human, but in Russia no cases of human infection have been officially
registered. The greatest fear is that the virus will mutate and a strain will
emerge that can be passed from human, to human, triggering a global epidemic.

August 2, 2005: A British pharmaceutical firm states that they
have developed a vaccine for the deadly H5N1 virus, commonly known as the
avian bird flu.
The
vaccine is unique in that it is DNA-based, as other bird flu vaccines are
derived from a developing egg. This proves beneficial, as egg-produced
vaccines can take up to six months to produce, while the latest DNA vaccine can
be produced at a much faster rate. Dr Clive Dix, CEO of PowerMed, the
manufacturer of the vaccine, believes that if necessary, 150 million vaccines
could be produced in three months. Dix also states that another advantage of the
vaccine is its ability to adjust to any mutations present in the bird flu, as it
would take a simple alteration in the genetic code to adapt the vaccine.

during an inspection trip to the Novosibirsk region Tuesday, saying the outbreak
was being successfully contained. Almost all the humans who have been killed
contracted the virus from poultry, but experts worry it could mutate into a more
deadly virus that could spread from person to person.

August 2, 2005: Three Villages Razed In Qinghai After H5N1 Bird Flu
Riots. According to the Qinghai Bulletin Board Service (BBS), the state of
emergency imposed on the farming community and its surroundings in the
Northwestern Qinghai City / Town of Yushu was lifted on the night of 28th July.
When natives living further from the area made a trip to the farming community,
they discovered that it had "vanished" together with 3 of its
surrounding villages. Only some ruins, blocks from collapsed walls, remained.
Apparently, the farms and villages had been flattened and there were signs that
they had been razed. It is believed that some inhabitants from those 3 villages
were workers in the farm. Around 200 people were estimated to have inhabited or
worked in those 3 villages and the farm. There whereabouts are, as yet, unknown.
The above translation of a boxun report suggest that three villages were razed
in response to unrest linked to a forced
bird flu quarantine in Yushu
in northwestern Qinghai in China. China has imposed news
blackouts and arrested
reporters in the past, so verifiable news from the area is difficult to obtain.

July 26, 2005: A laboratory jointly run by universities in Hong and
China said on Tuesday it had suspended studies into the H5N1 bird flu virus
after Beijing issued new guidelines which triggered fears of a crackdown on
academic freedom and independent research into the deadly disease. The new
rules were issued on May 30, five days after the Joint Influenza Research Centre
sent an article to the international journal Nature which said that infected
wild birds in western China might have picked up the virus from poultry farms in
southern China. A day after the article was published, Jia Youling, director
general of the Ministry of Agriculture's Veterinary Bureau, criticised the
findings and said no bird flu had broken out in southern China this year. The
closing of an independent lab in China is cause for concern. The lab has
been doing H5N1 research in collaboration with Yi Guan's lab at Hong Kong
University. The publication in Nature clearly demonstrated that H5N1 was
present in 2005 in eastern China, even though China had filed
no OIE reports in 2005 prior to the May 21 report
on Qinghai Lake. Subsequent reports were filed on outbreaks in Xinjiang
province, but there are still no reports of H5N1 in China in 2005 east of Qinhai
Lake.
China's actions strongly suggest they want to
control and withhold vital information regarding H5N1 in China.
The timing of the new announcement, in view
of the 20 isolates deposited at GenBank and Los Alamos (which included all 12
isolates collected at Qinghai Lake), as well as the virulence of the Qinghai
isolates, increases concerns that there is a raging
pandemic in China and information on H5N1 is being withheld.

Scientist July 16, 2005: In the spirit of the 1930s Soviet biologist
Trofim Lysenko,
China is ignoring science it finds
inconvenient.
The head of the ministry of agriculture's
veterinary bureau, Jia Youling, has rejected research on bird flu published
in the journal Nature last week by Yi Guan and his colleagues at the
universities of Hong Kong and Shantou. The paper concluded from genetic
analysis that the H5N1 bird flu killing migratory birds at Qinghai Lake in
north-west China had come from southern China. An independent team in Beijing
reported similar findings.
Chinese officials had claimed that the virus
came from another country. Last week Jia told the official Xinhua news service
that Guan's paper "made the wrong conclusion" and "lacks
credibility" because birds do not fly to Qinghai from southern China - even
though this is a well-known migratory route.
Ominously, Jia added that Guan's group did
not even go to Qinghai or have permission to do the research, and that his lab
does not meet safety standards. Yet Guan's BSL3 lab complies with international
standards, and his team collected samples from Qinghai before the government
introduced rules last month saying no one could study dead animals or bird flu,
or even report an outbreak of animal disease, without permission. "They are
trying to close everyone's lab," Guan told reporters.

Manila
Times July 7, 2005: World Health Organization scientist Hitoshi
Oshitani spends his days planning for a nightmare scenario—a bird-flu pandemic
among humans that would kill millions and bring nations to their knees. There
is much that experts still do not know about the deadly H5N1 strain of avian
influenza—exactly how humans contract it from infected poultry, and why so
many of its victims are healthy youngsters. But Oshitani says they do know
vulnerable countries are ill-prepared and that if the virus mutates and
erupts among humans in one of Asia’s crowded mega-cities, it will be
impossible to prevent it from becoming a pandemic. “If a pandemic
starts we cannot do anything to stop it. What we can do, once a pandemic
starts, is just to reduce the negative impact by being better prepared,”
said the Manila-based WHO policy-maker. “It’s probably just a matter of
time. Every 30 to 40 years we have had a pandemic,” he told AFP on the
sidelines of an international conference on bird flu held this week in the
Malaysian capital. “Usually for influenza, it’s almost impossible to
control. That’s why we have huge outbreaks every year.” To date, most bird
flu victims have caught the disease from animals, but the fear is it will
mutate into a form that can spread easily among humans, triggering a
contagion that could kill tens of millions of people.
“Our window of opportunity will be just two
or three weeks,”
he says. After that the virus would almost
certainly have moved on. And in teeming cities like the Thai capital Bangkok or
Vietnam’s Ho Chi Minh City, the sheer mass and movement of people would mean
the virus would have to be allowed to run its course through the population.
“There are no other alternative tools to stop the spread,” Oshitani said.
What would happen then is the stuff of
nightmares. Water and electricity
supplies could be disrupted because utility workers are too sick to maintain
them, the public transportation system could be abandoned for fear of infection,
and those who cannot afford drugs would succumb in huge numbers. “If more than
20 percent of the population is affected, it could affect a whole range of
social activities,” Oshitani said, adding the crisis
would no longer be just a health issue, but
one which could damage entire economies.
“People do not want to get infected in a bus or the train. People may not want
to go to the supermarket. So how to maintain that social life is a big
challenge, particularly in urban areas.” Oshitani said there were worrying
signs a mutation is looming. Growing numbers of people are being infected with
bird flu—64 cases have emerged in Asia so far this year, compared with 44 for
the whole of 2004. The disease is still circulating widely in the region, and
the virus has continued to change and mutate since jumping to humans in 1997,
when it killed six people in Hong Kong. Since resurfacing in 2003, it has killed
55 people in Asia including 39 in Vietnam, 12 in Thailand and four in Cambodia.
“These are all bad indicators in terms of the risk of a pandemic,” he said.“If
you start thinking of what you should do after a pandemic starts, it will be too
late,”
he warned.

July 7, 2005: UNITED Nations agencies and health experts yesterday
unveiled a multi-pronged strategy against bird flu, calling for Asian
governments to overhaul backyard farming practices and vaccinate poultry to
prevent the disease from becoming a human pandemic. The plan, hammered out
after three days of deliberations, "gives us a real chance to make a mark
on history as long as we work together with maximum energy and commitment",
Mr Omi said. The UN plan focuses on educating small-time farmers and their
families about the risk of living in close proximity with animals, and of
combining various species such as chickens, ducks and pigs in one enclosure.
Health experts say such practices increase the danger of the avian flu virus
moving from one species to another and possibly mutating into a new strain more
easily transmitted between humans than the current H5N1 virus. The virus
currently appears to spread to people mainly when they come into close contact
with sick poultry. Medical experts fear a mutated form could trigger a global
pandemic. Delegates also expressed concern about the open vegetable and meat
markets of Asia, where animals are often slaughtered in unsanitary conditions.
This threatens the health of humans who are exposed to contaminated blood,
faeces, feathers and carcases, the statement said. "The meeting agreed that
the avian influenza situation in Asia is extremely serious, but determined that
there was still a window of opportunity to ward off a pandemic," it
said.

World Health Organization officials said Tuesday

Julie Hall, a WHO expert investigating the outbreak, said that a Chinese
government lab had analyzed virus samples from infected birds in Qinghai
Province, but that the Chinese government had yet to share that information with
the organization or with other countries. "Our understanding is that
the virus has been isolated and sequenced," she said. "However, at
this stage we do not have access to the sequencing information, so we don't know
if the virus has changed." WHO officials also suggested that with migratory
birds acting as infectious couriers, analyzing the virus and limiting its
spread will be a daunting task that could be slowed by lack of information from
China.

June 28, 2005: An
influenza pandemic is coming-
public health experts worldwide agree. The main questions remaining are, when it
will happen, and how effectively our health care systems will respond to it. There’s
no way to nip this thing in the bud, it will happen. It’s just a question
of when,” said Dr. Trevor Corneil, Clinical Associate Professor at Canada’s
University of British Columbia and part of the province’s avian flu pandemic
planning team. Now there is
mounting evidence of human-to-human transfer,
an essential precondition for a pandemic to emerge. According to a recent World
Health Organization (WHO) report, although no human-to-human infection has been
confirmed, in Vietnam “the pattern of disease appear[s] to have changed in
a manner consistent with this possibility.” Another cause for concern is
the high fatality rate of those already infected. Of the 100 H5N1 human
cases recorded by the WHO in Vietnam, Thailand and Cambodia, 55 have died. “An
H5N1 virus with this ability could lead to a global pandemic and many millions
of deaths worldwide,” warns the WHO report. Australian Health Minister, Tony
Abbott, estimates his country could see “2.6 million Australians seeking
medical attention, 58,000 needing hospitalization and 13,000 deaths.” The
American Center for Disease Control and Prevention predicts that even a
“medium-level pandemic” would affect “between 15 percent and 35 percent of
the US population” and 2 to 7.4 million would die worldwide. “There is a
question about China,” says Corneil, describing the situation there as
“a big mystery.” Until recently, during the extensive bird flu outbreaks
in eight Asian countries, China admitted to only 50 cases which it
“successfully…brought under control,” according to China’s
state-controlled media. On May 21 of this year, the Chinese media confirmed the
Qinghai province deaths of 178 wild geese as a result of infection from the H5N1
virus. On May 24, the independent US-based Chinese website Boxun News reported
that 121 people in 18 villages had died in Qinghai due to “bird flu
infection.” Another 1,300 people were reportedly in isolation. According to
the report, “some of the family members of the victims have received
warnings. If they keep the secret, the authorities will compensate the family
members. Otherwise, they will be punished with the charge of ‘deliberately
spreading rumors to harm public security’.” The
WHO highlights the need for the world to take
action well before “there is unmistakable evidence that the virus has become

To head off a worst-case scenario, honest

June 28, 2005: An outbreak of avian flu in China is more lethal than
previously thought, UN experts warned today as they called for an immediate
and thorough study of the birds before it is too late. A total of 5000 birds
have died on an island in Qinghai province, north-west China, according to
officials from the World Health Organisation (WHO) and the Food and Agriculture
Organisation (FAO) who visited the area. "This is the first time we've
seen large numbers of migratory birds dying from bird flu," Julie Hall,
the WHO official in charge of communicable diseases in China, said. "So
the virus has obviously changed to be more pathogenic to animals. What it means
to humans we don't know."

June 25, 2005: "Everything suggests, that the situation we are in
now, there is a greater risk for a pandemic than for many decades,"
said Dr. Peter Horby, a medical officer and epidemiologist for the World Health
Organization in Hanoi. "The situation is much more complex than a year
ago." "This year, there doesn't appear to be a stop," said
Klaus Stöhr, head of WHO's global influenza program in Geneva. "Every
human case is worrisome because there is another chance for the virus to
[mutate] and a higher chance for a pandemic to occur." Stöhr said it
was unclear why human cases have not receded this summer. It could be better
surveillance or more instances of bird-to-human transmission. Or perhaps the
virus has become more adept at infecting people. Michael Osterholm, director
of the Center for Infectious Disease Research and Policy at the University of
Minnesota, sees the developments in Asia as more reason to worry. He doubts the
past will predict the virus' future. Unlike previous pandemics, where a virus
underwent a major genetic overhaul all at once, Osterholm said the avian
strain has been changing gradually since it was first identified in 1997. He
believes the virus will continue to transform, increasing the likelihood it will
ultimately lead to a pandemic. "We haven't done much to eliminate the
source in Asia," said Osterholm, a former bioterrorism special adviser to
the current Bush administration. "And there is a dynamic mutation
laboratory over there. I see nothing to slow down the mutations." The above
comments reinforce the notion that H5N1 is changing and becoming more
genetically complex.
Reuters
June 25, 2005: Vietnam's agriculture ministry was quoted as saying on
Saturday that the mutation of a bird flu virus was increasing the infection
possibility between humans. State-run media cited a ministry report as
saying laboratory test results overseas and at home showed the antigen
structure of virus is changing. "The ministry warned in the report that
the mutation of the H5N1 virus is raising the possibility of infections on
humans, because the test results of international and domestic laboratories
showed the virus's antigen structure contained a change," the Saigon Giai
Phong (Liberation Saigon) daily said. The mutation of the virus explains why
Vietnam did not detect major outbreaks in poultry in recent months but people
still fell sick of avian influenza, it said.

June 24, 2005: An international team of experts arrived in
Vietnam to study the likelihood of greater human-to-human transmission of
the bird flu virus. The top virologists and epidemiologists from Britain, Hong
Kong, Japan and the United States were scheduled to work with Vietnamese
scientists until the middle of next week. "These experts will be further
studying issues first raised at a WHO meeting in Manila in May 2005, including
the possibility of more widespread H5N1 human transmission, changes in the H5N1
virus, and the likelihood of increased human-to-human transmission," the
World Health Organisation (WHO) said Friday. Neighbouring China has had three
bird flu outbreaks in the past two months, leading authorities to cull thousands
of infected birds.

June 21, 2005: China today reported a new outbreak of deadly bird
flu which has infected 128 geese and ducks in the northwestern Xinjiang
region, killing 63 of them, the UN Food and Agriculture Organization (FAO) told
Agence France-Presse. The outbreak -- the third reported by the Chinese
government in the past two months -- occurred in Changji city near Urumqi, the
capital of Xinjiang, the FAO said citing Chinese government information. The
latest outbreak is also in Xinjiang Province in northwestern China. It is
about 30 miles northwest of the capital; city of Urumqi, which lies between the
early outbreak in water fowl, including migrating bar headed geese, and Tacheng,
located near the border with Kasakhstan and about 100 miles south of China's
border with Russia. The latest outbreak is similar to the outbreak near Tacheng,
with about half of the infected geese reported as dead. H5N1 usually does
not kill geese, so the finding of the three outbreaks close in time and location
suggests they are due to the same version of H5N1 and are being transported by
migrating birds. The latest report, like the two preceding reports, has
noted the lack of human infections. However, third party reports have
described human infections and fatalities
in the Qinghai Lake area as well as a pneumonia
isolation ward in Tacheng. WHO has requested on site visits to Qinghai and
Xinjiang. The request to vist
Tacheng in Xinjuiang has been denied,
fueling speculation that the patients and health care workers in the isolation
unit are infected with H5N1.

Embassy Japan June 20, 2005: "A pandemic of influenza could
result in 350 million deaths globally,” said Michael Osterholm of the U.S.
Department of Homeland Security, “and would cripple the global economy with
the suspension of international trade." Osterholm, associate director
for the National Center for Food Protection and Defense, spoke at a Council on
Foreign Relations meeting June 16. Osterholm characterized a pandemic
influenza as "the perfect storm" for the global economy because of its
potential effect on countries that depend on overnight international trade for
critical services. "Collateral damage from the pandemic would also be
significant because a suspension in trade would mean that countries will not
have access to imported products used for manufacturing, life-saving medications
and other consumer items," Osterholm said. According to Dr. Anthony
Fauci, director of the National Institute of Allergy and Infectious Diseases, mortality
rates would be highest among healthy adults between the ages of 20 and 40, a
grave consequence that would also result in a severe depletion of labor in some
countries. "One of the problems of bird flu is that there are no
naturally immune humans from this type of virus," Fauci said. "In the
past pandemics, there have been reservoirs of people with immunity from the
outbreak," he added. "We have every reason to believe that the H5N1
virus in Southeast Asia has the potential for a pandemic type of
infection," Fauci said. Osterholm noted it would take five to seven
years to develop the capacity for global influenza vaccinations.

have been destroyed 13 000 birds, as well as other measures taken including
isolation and disinfection. Besides, urgent poultry immunization was carried out
at all neighboring fowl-farms.In the Chinese experts’ view, bird flu virus
uprise at the west of China is connected with its carry-over by migrating birds
from the South Asia via Tibet and the Himalaya.

June 20, 2005: In a soon-to-be-released issue of a scientific journal,
researchers from Thailand and Hong Kong will report the findings of an autopsy
of a six-year-old Thai boy who died from avian influenza. Slated for publication
in the July issue of Emerging Infectious Diseases, their findings of an atypical
pattern of infection - deep in the lungs, away from the tracheal lining where
virus could easily be coughed out at others - may help explain why H5N1
influenza doesn't yet spread easily among people. While at least 54 people
have died from H5N1 infections since December 2003, autopsies have been
performed on fewer than a handful of cases. For cultural and other reasons, body
after body has been buried or cremated, robbing pathologists of the precious
chance to chart the havoc the virus wrecks on its victims. "That's one
of the reasons why it's so difficult to understand what the virus does in the
body," says Dr. Klaus Stohr, who heads the World Health Organization's
global flu program.

June 20, 2005: The World Health Organization and other international
agencies are looking into reports that Chinese farmers have been using a human
anti-viral drug to suppress bird flu. Some experts say such use may make
the virus resistant to the drug. Chinese officials had no immediate comment
on the report, which first appeared in the U.S. newspaper The Washington
Post. The newspaper said that Chinese farmers, with the encouragement of
the government, violated international livestock guidelines by feeding the drug
Amantadine - intended for humans - to chickens during the past several years.
That has experts concerned the drug would no longer help humans fight off the

June 19, 2005: China
ruins best chance of beating bird flu epidemic.
China has been trying to suppress a
bird flu outbreak by feeding poultry a human antiviral drug, threatening public
safety in the event of a global pandemic. China first reported an avian flu
outbreak in February last year. Yet for more than eight years, according to drug
company officials in Beijing quoted in the US media, the agriculture ministry
has been urging farmers to use the drug, amantadine, on infected birds, in
breach of international guidelines. It
explains why scientists discovered late last year that the virus had grown
resistant to amantadine, which cannot now be used to fight it in humans. Dick
Thompson, a spokesman for the World Health Organisation in Geneva, said last
night that the UN body had long suspected China of using amantadine on poultry.
Mr Thompson said that the drug, which is now ineffective against the H5N1
strain of the virus found in Asia, should have been a key part of the fight
against a global outbreak. "It would have been important in a pandemic and
it is a disappointment that it may have been lost to us." Chinese
farmers and officials from pharmaceutical companies confirmed that the drug
had been used since the late 1990s to treat sickly chickens and prevent healthy
birds from catching it. A farmer from Hebei province, near Beijing,
confirmed that he had been giving his chickens the drug for several years.
"Local government vets have always recommended it," he said. Three
years ago China was condemned internationally for trying to hide the extent of
the SARS outbreak, which ultimately infected 8,000 people and killed about 800.

June 17, 2005: The treatment of 23 bird flu cases [in Vietnam]
represents an all time high for confirmed or suspected bird flu cases.
An earlier
report described nine patients, which was followed by another report with
two confirmed patients and 5 patients positive for influenza A. Those five
were awaiting H5N1 test results. Thus it would appear that two patients
were admitted in the first week of June, 13 in the second week, and 8 more so
far this week. Although most of these cases are described as mild, the
positive result in the physician is a strong indication of human-to-human
transmission. The large
number of admissions this month clearly move the phase of the pandemic to 5.
Since these cases are mild, the number of unreported cases may be markedly
higher, indicating the pandemic in northern Vietnam has already moved to phase
6. Similarly, the unofficial reports on human cases in Qinghai
and Xinjiang
provinces in China suggest that region is also experiencing phase 6 pandemic
conditions, but with a strain that is markedly more lethal than northern
Vietnam. The major outbreaks demand a rapid response, yet there are no
publicly available 2005
H5N1 sequences at GenBank. Moreover, many suspect countries like India
and Bangladesh have yet to be H5N1 tested. As the pandemic of 2005 begins to
spin out of control, the monitoring of H5N1 reamins scandalously poor.

discover how the virus is transmitted and that almost all patients have had
direct contacts with infected poultry. The ministry has failed to explain why no
one was infected with the H5N1 virus in the 50 days prior to May 31. In
addition, the Ministry of Agriculture and Rural Development has affirmed that
there has been no bird flu outbreak nationwide for more than one month. However,
the ministry stressed that thus far all people contracting influenza type A from

June 17, 2005: A directive issued in
China appears to be restricting information on
the current H5N1 bird flu outbreak at all levels.
The latest outbreak began with a report on 180 dead bar
headed geese in Qinghai Lake Nature Reserve. All reserves in China
were closed when China announced that 519
birds had died and were positive for H5N1. A follow-up news conference
indicated over 1000
birds had died, which was unprecedented for H5N1, which usually is
not lethal in ducks or geese. Reports by nine students through Abundant
News at boxun.com indicated that over 8000
birds had died. Reports indicated that 6
tourists and 121
residents in the area also died. The government denied that there were
human cases and reports indicated that at least 8 of the 9 students had been arrested.
These reports were followed by reports of another outbreak near Tacheng City in
Xinjiang province. Geese
on a backyard farm began to die an they too were H5N1 positive. All of the
poultry in the area was culled and the outbreak was said to be contained.
However, reliable source indicated that a pneumonia cluster had developed at Tacheng
Hospital. Both patients and health care workers had been placed in
isolation. These reports fueled speculation that there were significant
numbers of human H5N1 infections and deaths in Qinghai and Xinjiang
provinces. Now China has announced limits on movement of samples out of China,
which is another indication that speculation about widespread efficiently
transmitted human infections were being covered up by the government and the
dead and infected patients signaled the beginning of phase
6 of the 2005 flu pandemic.

June 16, 2005: U.S. health officials and infectious disease experts have
been sounding the alarm for more than a year on the deadly potential of a
widespread pandemic of the bird flu troubling Southeast Asia. But their
warnings have become unmistakably ominous as they
struggle to convince the public and policy
makers of the need to prepare
for the mass casualties, chaos, and
devastation that will likely result if the disease spreads across the world. In
congressional hearings and on television, officials have repeatedly advised the
public of the potential for millions of casualties if bird flu gains the ability
to easily spread from birds to people or between humans themselves. But the
warnings have now become decidedly darker as
officials warn of a catastrophic economic
shutdown and a global political crisis
if bird flu strikes an unprepared world.
"This is much larger than a public health threat. The vast majority of the
world just doesn't get how vulnerable we are," says Michael Osterholm, MD,
associate director of the National Center for Food Protection and Defense in the
Department of Homeland Security and a former bioterrorism advisor to the Bush
administration. Osterholm complains that U.S. officials and companies have not
planned for the widespread logistical disruptions that would result if bird flu
were to spread within the next couple of years. Local and federal agencies
have not planned for widespread disruptions to schools and workplaces as the
public is told to stay home and gymnasiums are converted to emergency medical
facilities, he says. Travel restrictions and a run on vital supplies,
such as masks able to filter flu viruses, would "no doubt" lead to an
economic shutdown, he adds. What can the U.S. do to prevent the continued spread
of flu from billions of Asian chickens and ducks? "The bottom line message
is: almost nothing," says Osterholm, who is also a professor at the
University of Minnesota.

June 16, 2005: An Indonesian poultry worker has tested positive for
bird flu, in the country's first human case of the disease that has so far
killed 54 people in Southeast Asia, health officials said Thursday.
The worker on the island of Sulawesi is showing no symptoms of the disease, but
blood tests show he was exposed to the H5N1 strain of the disease and has
produced antibodies to it, said Hariadi Wibisono, director for the eradication
of diseases transmitted by animals at the health ministry.
"This is the first case found," Dr. Georg Petersen, WHO's
representative in Indonesia, told The Associated Press.
The Indonesian case is an ominous development in the global battle to prevent
the bird flu strain from mutating into a form that passes easily between people
and spawn a pandemic. Health experts have warned that Indonesia _ which
allocates only a tiny percentage of its gross domestic product to the health
sector _ may struggle to contain a major outbreak. Indonesia has reported scores
of outbreaks of bird flu at poultry farms across the country. "We have to
raise our guard once again," Wibisono told The AP. "There is a
possibility we will find more cases, but we hope that this does not
transpire."

June 14, 2005: Comments from the latest WHO update
on Vietnam describes three more milder H5N1 cases in northern Vietnam.
More geographical or familial relationships were not provided, but the trend in
northern Vietnam has been set since
the beginning of the year. The clusters
are larger and more frequent and the cases are milder. These milder cases
are similar to severe cases of human flu and therefore many
H5N1 human infections in northern Vietnam may go undetected. Sequence data
from northern Vietnam included an HA cleavage site missing an ARG. This
missing basic amino acid matches
the cleavage site from 2003 and 2004 isolates in Hong Kong and southeastern
China, raising the possibility that mild human H5N1 cases are also in China.
The homology
with 2005 Thailand isolates also raises the possibility of more human
infections there also. Recent comments
on the sequence of H5N1 from bar headed geese at Qinghai Lake also linked
bird flu there to H5N1 in southeastern China. The bar headed geese
winter in India
and Bangladesh and fly over Tibet to nest at Qinghai Lake in May and June.
Recently there have been meningitis
outbreaks in northern India, which coincide in time and location with the bar
headed geese migration. Interestingly, the crested
eagles smuggled into Belgium from Thailand had sequences matching those in
Thialand, but the eagles originated in Tibet. The linkage by time location
and sequence of H5N1 cases throughout southern and eastern Asia raise serious
questions about H5N1 monitoring of birds and people. The scandalously
poor monitoring significantly compromises flu pandemic containment
strategies.

millions of people after the mass deaths of wild birds in China. Unconfirmed

virus may have evolved to pass from person to person, breaking the final barrier
preventing a worldwide catastrophe. The Chinese government, while denying
the reports of human deaths, has adopted emergency measures in Xinjiang,
its remote north-western province, and has sealed off affected areas with
roadblocks and closed all nature reserves. "We are worried," says
Noureddin Mona, of the UN Food and Agriculture Organisation's representatives in
Beijing. "We should be prepared for the worst." Shigeru Omi, of
the World Health Organisation's regional director for the western Pacific, says "the
virus has become highly pathogenic to more and more species". "It
remains unstable, unpredictable, and very versatile. "Anything can happen.
Judging from the way the virus has behaved, it may have new and unpleasant
surprises in store for us."
AsiaNews
June 11, 2005: Greater vigilance and more transparency to monitor the
unpredictable evolution of bird flu… this is what Shigeru Omi, director of
the Pacific section of the World Health Organisation (WHO) said: “With bird
flu, anything could happen.” The H5N1 virus has now contaminated all Asia:
according to WHO sources, it is unstable and could evolve to the point of
reaching a high pathogenic rate [capable of affecting genes of different NDR
types]. WHO said that – compared to Vietnam – the virus has appeared at
its most pathogenic in China: its spread in Qinghai and in Xinjiang
[central-northern regions of the country] has killed several species of flying
creatures which had seemed immune to infection at first. The virus therefore made
a shift of species, and after recent cases of infection, WHO fears it
could pass to a phase of direct human contagion. In Vietnam, the H5N1
appears even more unstable: although the mortality rate dropped from 70% in 2004
to 20% in 2005, there have been cases of people infected with the virus who have
not shown any symptoms. “Information must be circulated in real time and with
total transparency,” said Omi. He called on the Chinese government to allow
WHO to carry out analysis of virus samples and on all Asian countries to develop
vaccines and to create antiviral medicines “in expectation of a possible
pandemic”. Hend Bekedam – director of WHO’s China section - said Beijing
had not yet given the go-ahead for an inspection of its territory.
TechNewsWorld
June 10, 2005: A top World Health Organization official Friday warned
that the avian flu virus is evolving quickly and urged heightened vigilance
because the strain in China appears to have increased in virulence.
Shigeru Omi, the WHO's Western Pacific regional director, said two outbreaks in
China's remote west in the past month have killed large numbers of species of
birds that had previously been relatively resilient to the disease. "The
outbreaks indicate that the virus has become highly pathogenic to more and
more species," he told a news conference. "The virus remains
unstable, unpredictable and very versatile," he said. Omi said the H5N1
virus is behaving differently in China and Vietnam. China has reported no
human cases of bird flu; Vietnam has had 38 of Asia's 54 human deaths. But the cases
in Vietnam appear to be becoming less deadly, with fatality rates dropping from
60 to 70 percent last year, to about 10 to 20 percent in 2005, Omi said.
Vietnam has also seen more cases where people are infected but don't develop
symptoms. "Anything could happen," he said. "Judging from
the way the virus has behaved, it may have new and unpleasant surprises in store
for us." The only way to safeguard against further outbreaks or worse
-- a mutation of the virus into a form easily passed between humans -- is
"heightened vigilance," he said. "Our work remains urgent,"
Omi said. That means it's imperative for countries to share information,
research and samples from their outbreaks with international agencies to
strengthen efforts to fight the disease, he said. Beijing has in the past been
criticized for its reluctance to release information on its outbreaks. Omi said
the WHO is looking forward to getting samples from China because
"sharing samples is very critical." WHO officials said they were
waiting for Beijing to approve a trip with Chinese health officials to Qinghai
province, where more than 1,000 wild birds, including geese and gulls, were
killed by the H5N1 flu strain in late May. Gao Qiang, China's health minister,
told reporters in Hong Kong that WHO teams would be free to visit infected
areas. "During the 2003 SARS outbreak, WHO experts were able to go wherever
they wanted. And with bird flu, there's no place they can't go," Gao said.
On Thursday, the Agriculture Ministry confirmed a second outbreak of bird flu in
the Xinjiang region. It said it had culled more than 13,000 geese at a farm
after discovering that about 460 had died from the virus. China said both
outbreaks appeared to be isolated incidents, with the case in Qinghai possibly
carried there by migrating birds.
Recombinomics
June 10, 2005: WHO comments that the H5N1 virus "remains
unstable, unpredictable and very versatile" highlight the need to
gather additional data. H5N1 evolves via recombination within hosts that
are infected with two viruses. As the number of hosts infected with H5N1
increase, the number of possible new recombinants also increase. New
emerging strains can be predicted based on the current gene pool, but the
holes in the database are substantial. WHO and FAO should be encouraging
affected countries to get more serious about collecting and sharing data. The
two most glaring examples are China and India. China has almost certainly
generated sequence data for the Qinghai Lake isolates.
This data should be publicly available via deposits at GenBank. Currently
there are no
2005 H5N1 sequences. China, Vietnam, Thailand, and Indonesia
certainly have sequences data, even if only from birds. The 2004 H5N1
bird sequences are virtually identical to the human sequences, so bird sequences
will be quite useful. The initial reports from Qinghai Lake described bar headed
geese as the only bird flu victims. Although the number of species
expanded, the bar headed geese are key. They winter in northern India and
can fly 1000 miles in 24 hours (the distance from northern India to Qinghai
Lake). There are almost certainly H5N1 sequences in India.
Although India has claimed to lack facilities to isolate and sequence H5N1 they
can simply pack up bird dropping and ship them off if they can't come up with
the appropriate resources. Similarly the meningitis
cases in northern India as well as the dying
crows in western India should be tested for H5N1. WHO has
previously indicated they will test unexplained deaths for H5N1. So far
there is little evidence that Meningitis / meningococcal deaths in the Philippines
and India
have been tested for H5N1. Like China's blanket denials
of human H5N1 cases, WHO blanket calls for vigilance are inadequate.
Media reports quote Chinese official as saying WHO is welcome to visit all areas
of China. Similarly, India has not told WHO or FAO to stay out. It is
time for WHO to get off the phone and get on
the ground in China and India to get real data on increasingly ominous
developments.

Organization predicts could infect 30 million and kill 7.5 million people
worldwide - has been lowering in the past few months while the risks remain just
as high, Center for Health Protection controller Leung Pak-yin said Friday. He
warned against taking Tamiflu, which is seen as the last defense against the
H5N1 virus, as a preventive medication for common flu. ``If people take
Tamiflu whenever they catch common flu, when a flu pandemic comes the virus may
already be drug-resistant, and that will affect the whole picture of infection
control,'' Leung said. ``When a flu pandemic hits, there will usually be a
second or third wave attack,'' Leung said. ``If we used up most of our stock
even before the pandemic, we would have no defense when the virus launched its
next round of attacks.'' ``Unlike Sars, we can hardly avoid contacting the
flu virus when the pandemic hits.``

June 1, 2005: The information on the over than 1000
dead birds near Qinghai Lake comes from many sources. Initial wire
service reports described the deaths of 178 bar headed geese. These
initial reports
clearly indicated that the deaths were not linked to bird flu. Follow-up reports
indicated dead birds had tested positive for H5N1, although the number and
relationship to the 178 previously reported deaths was unclear. Clarification
came from the initial report
filed by China to the OIE, which described 519 dead birds representing 5
species in Gangcha Province, Qingahia Province. These deaths were
laboratory confirmed. In the weekly
OIE report the 519 were again listed but the report indicated that the virus
isolated from the birds was H5N1 and was highly pathogenic in laboratory
infected chickens.
The official report was followed by a news conference, which was widely
reported. At the news conference the deaths of over 1000 birds were
reported and one media report indicated most were in Qinghai Province,
suggesting the bird deaths might be widespread. For the human cases, the initial
report came from Promed,
who had translated
the Abundant
News story. That report indicated six tourists had died.
Four were named and three of the four were from Chengdu, Sichuan Province (about
400 miles southeast of Qinghai Lake). The clustering of three deaths of
three tourists from the same location would be cause for concern. These
initial reports were followed by a report
of 121 deaths in 18 communities in Gangcha Province, along with 79 infections
generating a case
fatality rate of over 60%. Follow-up reports
included a smaller number of cases in more distant communities as well as a news
blackout, checks of computer, difficulties connecting to the Internet, and
related issues centered on limiting news. All of the reports linked to the human
cases come from the same source and have not been independently verified.
However, these reports are quite specific and the severity of the reported
events is quite clear and not lost in translation. If verified, these
reports would dwarf prior reports on human H5N1 cases and move the 2005 flu
pandemic from phase
5, which involve an increase in human-to-human transmission, to the final phase
6, which is sustained and widespread human-to-human transmission. Although
not verified, the reports via Abundant News are quite specific and consistent.
The disease described is somewhat atypical, involving fever and vomiting, but
not respiratory illness. The specifics in the series of reports are not
adequately addressed with blanket denials by official sources in
China.

News Today May 31, 2005: While the Indonesian government talks about
eradicating bird (avian) flu by the year 2007, WHO has stated that bird flu
is endemic in the country. Agriculture minister, Anton Apriyantono, expressed
disappointment at WHO's (animal health dept) declaration, saying cases of
bird flu have been declining in Indonesia since last year.

May 29, 2005: Roche Holding AG confirmed that huge demand for Tamiflu
-- the only drug deemed efficient against Asian bird flu -- is causing a
production bottleneck, with new customers likely to face waiting time of up to
two years. 'This is clearly a challenge for us,'
the Swiss pharmaceuticals group said. The sharp increase in new orders was
triggered by warnings by the World Health Organization (WHO) about a new bird
flu pandemic, which according to conservative estimates could lead to 28 mln
infections and up to 7 mln deaths. Tamiflu is the only drug that is able to
stop the massive reproduction of the H5N1 bird virus at an early stage of
infection. Moreover, the treatment works preemptively. According to Roche,
25 countries have already followed WHO warnings and have placed orders with
Roche or have signed a memorandum of understanding to build-up stockpiles of the
drug. In order to satisfy US demand, Roche plans to open a new production plant
in North America during the second half of the year. Major orders have also been
placed by the governments of the UK, France, Switzerland, Finland and Germany.

News Today May 28, 2005: An official from China's agricultural
department said the death toll from bird flu in the West of China is five times
greater than official reports had stated. The number of migratory birds
killed was much larger than people had thought, he said. He added that the
reports refer only to the death of birds and that no humans have died. Rumours
are rife among experts and throughout the internet that there has been a massive
cover-up. People are saying nobody really knows how bad the situation really
is/was. Rumours abound that many humans have perished. Officials now say
more than 1,000 migratory birds have died after being infected with the H5N1
strain of bird flu. The H5N1 is the most lethal one. Official reports had talked
about just 178 birds, all of them geese, perishing in Qinghai Lake - now, they
say the real number is over 500. China has not reported one human death from
bird flu - even though nearby countries such as Vietnam have had 38 deaths.
In total, the number of human deaths from bird flu in South East Asia has
totalled 54. Health experts say that in order to tackle a possible pandemic
which could spread to humans and become a human-to-human transmissible disease,
we need accurate, reliable information. If authorities are not able to
provide reliable figures it is virtually impossible to know what to do and when
and where to do it. A pandemic could kill millions and millions of people
throughout the globe.

May 27, 2005: Genetic analyses of samples from patients recently
infected with the H5N1 bird flu virus suggest that new strains are emerging
in the north of Vietnam. The report, posted on the World Health Organization
(WHO) website last week, says the data are limited and that more studies are
needed, but cautions against complacency in the face of the growing pandemic
threat (see Time
to prepare for bird flu pandemic 'running out'). At a WHO meeting in the
Philippines in early May, scientists also concluded that the transmission of
the virus from person to person could be more common than previously thought.
The data — from the Centers for Disease Control and Prevention in Atlanta,
United States, and Japan's National Institute of Infectious Diseases — could
signify changes in the virus because clusters of infection are larger and
more numerous than seen recently, and in some cases exposure to poultry could
not be traced.

May 26, 2005: China remains woefully ill-equipped for tackling avian
flu, a top scientist said, as other experts spelt out fears that hundreds of
millions of people may die or fall sick if the virus triggers a global pandemic.
David Ho, an internationally-renowned US researcher, said China had received a
wakeup call in 2003 after its initially tardy and secretive response to Severe
Acute Respiratory Syndrome (SARS). But the new political will to strengthen
China's rickety medical infrastructure had yet to be matched on the ground, and
this has left the country dangerously exposed to avian influenza, Ho said.
"There is little doubt that China will be in deep trouble if the flu
pandemic were to strike in the next few years," Ho, who works at the Aaron
Diamond AIDS Research Center in New York, said in a commentary published by the
British science journal Nature. "It has a moral obligation to its own
people, and to the world, to rectify the situation as soon as possible."
The problems highlighted by Ho include a "grossly underfunded"
epidemiological system to spot disease outbreaks; an inefficient alert system to
warn and advise hospitals, doctors, officials and the public; and decrepit
healthcare infrastructure and poorly trained physicians.

May 25, 2005: The Director General of the World Health Organization last
week referred to avian influenza (bird flu) as the "most serious known
health threat the world is facing today." Dr. Lee Jong-wook made the
statement as he concluded his opening remarks to the 58th World Health Assembly
in Geneva, Switzerland last Monday. The Assembly ended today after adopting
revised International Health Regulations that govern national and international
response to disease outbreaks. "The timing cannot be predicted, but rapid
international spread is certain once the pandemic virus appears," Jong-wook
said about avian influenza. "This is a grave danger for all people in
all countries."
Time
May 23, 2005: The most frightening aspect of avian flu has always been
its astonishing virulence, but the human death rate in hard-hit northern Vietnam
has fallen to 34% this year, down from almost 80% for the entire country in
2004. Good news? Not if you're an epidemiologist. Investigators for the World
Health Organization (WHO) have raised concerns that even though the H5N1
bird-flu virus appears to be weakening, it may be adapting better to human
beings potentially opening the door to a flu pandemic. Researchers have
found that as the fatality rate dropped in northern Vietnam, there has been an
increase in the number of cases clustered close together and in the age of
those infected signs that the virus may be finding more efficient ways to
infect people, including human-to-human transmission, the principal barrier to a
pandemic. The falling death rate could mean that this process of
adaptation is accelerating. "In gaining the ability to go from one
person to another, a virus may well lose its virulence," says Dr.
Jeremy Farrar, director of the Oxford University Clinical Research Unit at the
Hospital for Tropical Diseases in Ho Chi Minh City. The 1918 Spanish flu, for
example, the worst pandemic in history, had a fatality rate of 2.5%. But it was
extremely contagious, infecting hundreds of millions. The data from Vietnam is
still far from conclusive, and the reduced fatality rate may be due to more
experienced investigators detecting the sort of mild cases they might have
missed last year. But that wouldn't explain the difference between situations in
Vietnam's north and in the south, where the death rate has remained high and
infections have remained comparatively low. Either way, public-health experts
are preparing for the worst. Says Dr. Peter Brown, a WHO epidemiologist:
"If we wait until we definitely know there is a problem, it may be too
late."

May 23, 2005: Bird flu may have claimed the life of a Vietnamese man
in the past week, bringing the country's toll to 18 since the latest
outbreak in late December, health officials said on Monday. A provincial health
official told Reuters preliminary tests by the Hanoi-based National Institute of
Hygiene and Epidemiology had confirmed the 46-year-old man from the northern
province of Hung Yen died last Thursday at a Hanoi hospital from bird flu.
The official said by telephone from Hung Yen, 64 km (40 miles) southeast of
Hanoi, that the man was admitted to hospital a week ago with a high fever and
coughing. A Health Ministry spokesman said the man's death was still not
officially recognised as being caused by the H5N1 virus.

May 20, 2005: The world is one step closer to a devastating killer
flu pandemic, World Health Organization (WHO) experts suspect. Two
developments in northern Vietnam spur the renewed concern:
Deadly
bird flu infections are being seen in larger clusters of people -- with a much
wider age range -- than ever before.
The
virus is changing in ways that suggest it may be adapting to humans.
Also
of concern is the revelation that one virus isolate was partially resistant
to TamiFlu, the only effective treatment for human infection with type H5N1
bird flu.
Because
of these developments, the WHO urgently convened a panel of experts that met
earlier this month in Manila, Philippines. The panel's report, written on May
11, was released yesterday. "All countries, both those affected and
unaffected by avian H5N1 … should move ahead as quickly as possible and
develop or finalize practical operational pandemic preparedness plans," the
panel advised.
The
WHO lists six stages leading from the detection of a new flu virus in animals to
a global human flu pandemic. So far, the H5N1 bird flu has been at stage 4:
small, highly localized clusters of human infections. At this stage, the virus
cannot spread easily from person to person. The new evidence suggests -- but
does not yet prove -- that bird flu may be moving to stage 5. That would
mean the virus is becoming increasingly better at person-to-person spread.
When stage 6 is reached, there will be rapid human-to-human flu spread and
pandemic flu. It's only a matter of time, says virologist Klaus Stöhr, PhD,
DVM, project leader for the WHO Global Influenza Program. "We are in a
situation where we simply have to deal with uncertainties on when this will
happen -- not whether this will happen or not," Stöhr said yesterday in a
news conference. "We believe a pandemic will happen, but we don't know when
and also [we don't know] the severity of the event." The last flu pandemic
was in 1968. That means that this is the first time the world has had the tools
in place to track a flu pandemic as it develops. Guénaël Rodier, MD, MSc,
director of the WHO Department of Communicable Disease Surveillance and
Response, says it's becoming clear that there are many small steps -- rather
than alarming leaps -- that lead to a flu pandemic. "There is no
evidence of a big crisis," Rodier said at the news conference. "But
there are enough elements to say there may be something going on. … We have
enough data to be concerned. At the same time we don't have enough data to be
sure." "In the last 18 months, we have seen an incremental increase in
our concern," Stöhr said. "We do not know if a pandemic can
occur next week or next year."

May 14, 2005: Indonesian researchers have found a strain of bird flu
in pigs on the densely populated island of Java, raising fears the virus
could more easily spread to humans, the government and scientists said Saturday.
The scientist who made the discovery identified the strain found in the pigs
as H5N1, the same version of the virus that has jumped from chickens to humans
elsewhere in Southeast Asia, killing 36 in Vietnam, 12 in Thailand and four
from Cambodia. Until now, human infections have been traced to direct contact
with infected poultry or poultry waste, and millions of chickens and other fowl
have been slaughtered in attempts to stem the disease. But last fall, the World
Health Organization urged scientists to examine other mammals, in particular
pigs. Pigs, which are genetically similar to people, often carry the human
influenza virus. Experts worry that pigs infected with both bird flu and its
human equivalent could act as a "mixing bowl," resulting in a more
dangerous, mutant virus that might spread to people more easily -- and then from
person to person. Indonesia has yet to report any case of humans contracting
bird flu, but has reported scores of outbreaks at chicken farms around the
sprawling archipelago.

May 13, 2005: It's impossible to say whether recent changes in both the
pattern of human cases of avian influenza and in the genetic makeup of the
circulating viruses mean the risk of a flu pandemic has risen, the head of the
World Health Organization's influenza program said Wednesday. Dr. Klaus Stohr
said experts can't make that judgment, because too little scientific informa
tion is flowing out of Southeast Asia to the WHO's network of reference
laboratories. "The data in humans is inconclusive and is too incomplete
to draw any profound conclusions," Stohr said from Hanoi, Vietnam, where he
is attending a second meeting of experts in as many weeks on the H5N1 problem.
The agency has recently acquired some new genetic information that may help it
in efforts to reassess the risk posed by the H5N1 virus, he suggested. Analysis
of the new data confirms the virus is changing. But what that signifies remains
a mystery, Stohr said.

May 13, 2005: [In India] Two more people died of meningococcemia in
the capital yesterday. The disease is displaying characteristics never seen
before. It is supposed to occur among children aged between 1-5, but the worst
hit are adult males in the 15-30 age group..... There have been 260 suspected
cases and 20 deaths in the space of one month. Though these figures have
alarmed some people, the government maintains the situation is well under
control.
The
meningococcemia / meningitis outbreak in India has some striking parallels with
the outbreak
in the Philippines. There have been no reports on bird flu tests
on these patients, even though the infections are clustered, spreading rapidly,
and affecting an unusual age group. Previously, WHO had said that clusters
of unusual deaths would be tested for H5N1. There is little evidence for
such tests and there are significant concerns about the sensitivity of such
tests. Moreover, menigococcemia is a known secondary infection of
influenza. Recent reports of H5N1
antibodies in poultry workers in India raise a red flag on bird flu.
The sera were from 2002, but the monitoring of bird flu in India has been
minimal, and there have been no attempts to isolate or sequence the virus.
Thus, the current bird flu situation in India is not well understood. In
Vietnam a high percentage of ducks are asymptomatically
infected with H5N1, and an increasing percentage of chickens are also
asymptomatically infected. False
negatives in humans are frequent in both northern and southern Vietnam, so
the distribution of the virus in endemic areas is not monitored well, and the
evolving virus is becoming increasingly difficult to detect with probes
directed against earlier isolates. Similarly, the probes being used to detect
WSN/33 H1N1 in Korean pigs also yield false
negatives, as the number of fatal swine infections increases and spreads. Bird
flu appears to be spreading in greyhounds
in the United States leading to unprecedented levels of fatal infections which
are being diagnosed as an unusually aggressive form of kennel cough, although
the descriptions match the fatal
H3N8 infections in Florida
last year. Although WHO has complained
about a lack of samples, they have indicated that the were too busy to verify
the fatal swine infections in Korea. Moreover, the WHO makes
pronouncements about the absence of reassortment in Vietnam H5N1 isolates,
although they have very limited data. Likewise, there has been no
announcement on the fatal infections in dogs in the Untied States. Explanations
for the meningitis outbreaks in the Philippines and India have also been
lacking. The recent infections of people, birds, pigs, and dogs create
striking parallels
with the 1918 flu pandemic. The fatal infections in the fall were
preceded by mild but unusually widespread reports of atypical infections in the
spring. Although it is 87 years later and the number of scientific and
medical advances has been significant, simple monitoring of various influenzas,
including H5N1 is scandalously
poor.
