Due to circumstances beyond my control, computer glitch (?), the length
of the former thread (Thread 2), and the tremendous amount of new
information coming in at this time, it is probably necessary to start a new
thread on Avian Influenza Awareness.
I pulled out the following commentary from an earlier thread regarding
a rather chilling video (at least to me), given by Dr. Margaret Chan. The
information is not current as the video was shot in February 2007, but
what she has to say is still pertinent considering how much further the
spread of H5N1 has grown. It is now on three continents with a CFR (case
fatality rate) for human beings of over 60%. It is still however, primarily
a bird disease, but that may be changing.
From Margaret Chan MD, Director-General of the World Health Organization:
I did not attend the CIDRAP Conference in February, 2007 where this video
was shown. I almost got there, but changed my plans at the last minute.
Dr. Chan will appear in a screen to your right. You do not have to press
any buttons, just wait for the screen to appear, and for her presentation
to begin. You do not have to be a subscriber for the video to play.
Just be patient for a few seconds and view it.
I have to say that even though everything Dr. Chan is saying in this
presentation is well known to me, just hearing her speak so
clearly and honestly of what might occur, has shaken me. Though
many who research this information will say that her estimates
of the possible future cases may be too conservative, the numbers are
still hugh. This event will change the world, and challenge all of us.
The video will take 16 minutes of your time. I hope that the
very serious nature of Dr. Chan's message will cut thru the apathy and
disbelief about the possibility of H5N1 triggering the next pandemic,
and encourage some individual planning and family preparation.
Share it with people that you care about.

"...the job of the media, everywhere, should be to comfort the afflicted and
afflict the comfortable" - Crawford Kilian
When peer reviewed journals fail to peer review, and the media doesn't even
notice, the world is a less healthy place for all of us.
The following link allows you to follow a conversational thread,
revealing a story about a failure of integrity by researchers, a govt agency,
science journals, and the media. You might not understand all of it, but I think
most will be able get that there are problems with how research gets reviewed
and reported. If you have been following the news on H5N1 then you already
know that viral sequences are being withheld by WHO affiliated labs including
the CDC, and that researchers treat this information as their own property. While
bird flu continues to spread, research continues at a leisurely pace as if there
were all the time in the world, and that the withheld sequences have no impact
elsewhere.
The GenBank sequence database is an open access, annotated collection of all
publicly available nucleotide sequences and this is where we would like all
of the privately held sequences to go.
E627K is a single nucleotide polymorphism called a snip [sNP] for short.
This SNP is found in all human seasonal influenza. It allows a flu virus to
have some selective advantage in targeting mammals like us because it
permits the virus to infect at the lower temperatures of the mammalian nose.
Birds have much higher body temperatures. If a bird flu virus has this SNP,
it has made an adaptive change by exchanging genetic material with another
flu virus, probably a human seasonal flu virus since all of them contain E627K.
This link tells the story about how the research involved in two different peer
reviewed papers on another group of bird flu viruses, the H7 viruses, has
been poorly covered. The information that was not covered was very important
to the preparedness effort. Maybe these were just honest mistakes, and the
researchers just goofed or maybe not...
At any rate the two journals, and the media have fallen down on the job.

UPDATE:
http://www.recombinomics.com/News/06020803/H7N2_Replaced.html
Looks like like they made an error, and have corrected it however, this still does not
excuse the peer reviewed journals or the media for not holding them accountable for
not releasing the accession numbers in their papers or the full gene sequences.
The PB2 sequence has not been released. Why are they not releasing the
sequences that their research is based upon, and why is this behavior condoned?
http://www.flutrackers.com/forum/showpost.php?p=160996&postcount=12...the apparent reassortant was presumably due to submission errors for these four genes. The banner was removed from the three avian genes (HA, NA, NP), which were deposited in March and released in April.
The H7N2 isolate from a patient who was hospitalized in New York in 2002 attracted significant interest because of increased affinity for human receptors and transmission from ferret to ferret.
Release of the PB2 sequence would be useful.
... The sequences were never listed at either publication (J Virol last year or PNAS last week). The notices and replacements were all done at Genbank.

They do not list every H5N1 event but give a good overview of what has
happened, enough that you can see the spread of the disease across the
planet. For anyone still thinking that this is just in southeast Asia, you are
going to be in for a surprise.
The UK
http://afludiary.blogspot.com/2008/06/uk-h7-outbreak-highly-pathogenic.html
All of the news lately seems to be about H7 viruses. Today we are hearing
about a highly pathogenic avian influenza [HPAI] occurring in poultry in
the UK. Humans can be infected with H7 viruses also which is why any
people at risk there will be offered Tamiflu not just for their own safety
but for everyone else as well. H7 viruses can be transmissible to others.
While outbreaks of H7 strains of bird flu have occurred in Britain before, they have always been characterized as `low pathogenic', or one that causes less mortality and morbidity among poultry.
Obviously, highly pathogenic viruses are of greater concern to the poultry industry and to public health officials. While the risk to humans from the H7 virus has historically been low, it is not zero.
Local health departments will reportedly track down contacts with the infected birds and offer antiviral medication where appropriate.
Arkansas - USA
http://www.recombinomics.com/News/06040801/H7N3_AR.html
H7N3 now being reported in Arkansas. Tyson Foods is spinning out
reassurances to the public that none of the birds have entered the
food chain. They are saying that they discovered the virus during
routine surveillance.
The...comments describe the detection of H7N3 antibodies in poultry flocks
in Arkansas. However, the reports also highlight surveillance failures
of finding H7N3 in wild birds prior to the outbreak, as well as H7N3 virus
prior to the development of antibodies in the affected flocks.
A recent report has raised questions about mismatched primers used to
detect H7 in wild birds. These primers do not match the H7 in the birds,
and therefore produce false negatives. It is unclear if this flawed approach
contributed to the failure to find H7 in the hens with H7N3 antibodies.
...the possibility of human infections in Arkansas is real, but unlikely to be
reported because of a fatally flawed surveillance program in North America,
which has failed to find H5N1 in wild birds, although PCR confirmed H5 was
reported in a dead gosling (in association with the death of all 3 goslings)
on Prince Edward Island.
The Difference Between Highly Pathogenic and Low Path Flu Viruses
http://www.flutrackers.com/forum/showpost.php?p=161500&postcount=22
A simplified explanation that is adequate for understanding these articles.
Remember though that with low path flu viruses, only a smaller percentage
of birds die or in some cases, there is no sign of infection, but the poultry will
always have to be culled because of the possibility that the virus might evolve
and become highly pathogenic.
The Silence from Indonesia Is Deafening
Here are a few links on what we are not hearing from there.
http://crofsblogs.typepad.com/h5n1/2008/05/who-relapses-in.html
On May 21, I posted this story: Indonesia confirms its 109th H5N1 death.
That was about the death of a 16-year-old girl with the beautiful name of
Istiqomah; she had died on May 12.
Ten days later, the World Health Organization has still not reported her death
as a confirmed H5N1 case. For that matter Indonesia's ministry of health hasn't
posted anything about it either, and Komnas FBPI has issued no follow-up.
Evidently, this is the same girl, and they will no longer be reporting these
deaths taking place in the country with more H5N1 victims than any other
nation.
http://crofsblogs.typepad.com/h5n1/2008/06/indonesia-anoth.html
A 15-year-old Indonesian girl died quietly of bird flu last month, but the health
ministry in the nation hardest hit by the disease decided to keep the news quiet.
It says it sees no benefit to formally announcing deaths linked to the H5N1 virus.
Confirmed: Supari is suppressing H5N1 death reports (updated)
http://crofsblogs.typepad.com/h5n1/2008/06/confirmed-supar.html
Please be aware that Indonesia is no longer allowing the release of information
on deaths from H5N1. This is also the same country that has been refusing to
allow viral samples to be sent to the WHO affiliated labs claiming that it is
intellectual property. By withholding these two pieces of information, Indonesia
places all of us in danger. We are now totally dependent on underground news
sources that risk the displeasure of Indonesian authorities to alert the world of
what is taking place there. The translators from the flu forums are now very
experienced at extracting information from the "boots on the ground" sources,
but the job is now more difficult than ever. Should a pandemic event arise from
that country, we might not have the early warning signals that we might otherwise
have had. This is very unfortunate and risky for the rest of the planet.

Indonesia H5N1 Cluster Reporting Failures Increase Concerns
Health Minister Siti Fadillah Supari, who has clashed with the international
community and United States over her handling of health issues, on Thursday
said her ministry had changed its policy and would only report cases every
six months.
She did not say whether that reporting policy also included the World
Health Organization (WHO). But a health ministry official said on Friday that
the ministry had not decided yet whether it would report to the WHO every one,
two, or three months.
"We are obliged to report to WHO, we are also obliged to report it to the
public," said Nyoman Kandun, director-general of communicable diseases at
the health ministry, adding that the new policy was meant as a better way
to "package" the information.
The above comments are out of compliance with the 2005 revision of
the International Health Regulations, which specifically cite "human influenza
caused by a new subtype" as a notifiable disease which is to be reported to
WHO within 48 hours.
The comments on the new Indonesian policy, have been raised in response
to an H5N1 fatality that was not reported for over a month. The case
received considerable local media attention, because the brother of the
confirmed case had died days early with identical symptoms, including
cyanosis in extremities. There was little doubt that these fatalities represented
an H5N1 cluster, which followed two other clusters involving fatalities which
included H5N1 lab confirmed cases.
In each of these clusters, the index case was mis-diagnosed and the mis-
diagnosis was obvious because of the H5N1 lab confirmation in a fatally
infected relative. In one cluster the index case was said to have died
from respiratory disease. This cluster was only covered by the local media.
However, the second cluster was picked up by wire services, and Nyoman
Kandum was specifically asked about the death of the index case and he said
the brother died from dengue fever. This comment raised significant doubt
about H5N1 transparency in Indonesia linked to significant under-reporting of
cases and clusters.
The most recent cluster has still not been listed by WHO as a lab confirmed
case, although media reports indicate H5N1 has been confirmed by two or
more independent labs. The delay was said to be due to a consideration of
the new reporting policy. In this latest cluster, the brother's death was mis-
diagnosed as typhus.
These mis-diagnosis are obvious, and are usually corrected when H5N1 is
confirmed in a relative who has disease onset dates within days of the
earlier case. In all three of these clusters, the time differential in disease
onset dates strongly suggesting that these clusters represented human to
human transmission, yet none of the clusters have been acknowledged or
reported to WHO...
The decision to revise the reporting frequency, in clear violation of
International Health Regulations [iHR], is cause for concern, as is the WHO's
failure to investigate the index cases in each cluster. Although H5N1 clusters
are not new in general or to Indonesia in particular, the failure to investigate
these clusters has created conditions that allow for less transparency.
Although H5N1 infections have recently been reported at record levels in
India, Bangladesh, and South Korea, many media reports assume that the
decline in confirmed human cases reflects a reduced risk and a lower incidence
of human H5N1 infections. However, the limited number of human cases in the
above outbreaks, as well as the outbreak in Pakistan, is almost certainly due to
detection / confirmation / reporting failures.
These failures, and the WHO's acceptance of this lack of transparency,
encourages countries to conceal cases and / or announce new reporting policies
in clear violation of IHR.
The WHO has an obligation to enforce these regulations, which it has avoided
for some time, and reporting failures have been most obvious in recent months.
Bird flu mixed with human virus could form pandemic: research
http://www.abc.net.au/news/stories/2008/06/06/2267791.htm?section=justin
A new research paper has been published in the United States, proving that
bird flu, which has so far only killed people in its pure form, is capable of
combining with conventional human flu viruses.
A mutated virus combining human flu and bird flu is the nightmare strain
which scientists fear could create a worldwide pandemic. The pure bird flu
strain, called H5N1, has caused hundreds of deaths recently around the
world.
The research has emerged at the same time as other worrying news. The
Indonesian Government has announced it will stop reporting bird flu deaths
as they happen, apparently because it does not want bad news to spread.
Professor Anne Kelso from the World Health Organisation (WHO)
Collaborating Centre in Melbourne says such a move would hinder efforts to
contain any outbreak.
"The sharing of information and the sharing of viruses [for research] are the
two most important things that countries can do to help the world prepare for
a potential pandemic," she said.
"We don't need to know who the people are. It's very important we know
where the deaths are occurring and if possible to have access to the viruses
to compare with other viruses from around the world."
"The WHO on behalf of all the member states will have less warning if there
are changes happening that could lead to a pandemic," she said.
"In particular it's important to know whether the deaths are due to exposure
to viruses in poultry or whether there's evidence that they are being
transmitted from human to human."
The News from Hong Kong
http://www.flutrackers.com/forum/showpost.php?p=162295&postcount=9
Highly pathogenic avian influenza (HPAI), H5N1 was found during routine
surveillance that tested poultry droppings in a wet market. The birds did
not appear sick. That is why routine testing is now necessary. There is
no longer any guarantee that there would be any warning of infection
because the birds do not always show symptoms right away. Now they
will have to monitor the handlers, and put them on Tamiflu. They will
cull just these 2700 birds for now, and try to track where they came
from.
Why the concern? Check out this link on what happened in Hong Kong
in 1997.
In 1997, at least a few hundred people became infected with the avian
A/H5N1 flu virus in Hong Kong and 18 people were hospitalized. Six of the
hospitalized persons died. This virus was different because it moved
directly from chickens to people, rather than having been altered by infecting
pigs as an intermediate host. In addition, many of the most severe
illnesses occurred in young adults similar to illnesses caused by the 1918
Spanish flu virus. To prevent the spread of this virus, all chickens
(approximately 1.5 million) in Hong Kong were slaughtered. The avian flu
did not easily spread from one person to another, and after the poultry
slaughter, no new human infections were found.
This is from today in Hong Kong:
...our existing guideline is if there is one detection of H5N1 in one market,
we will cull the chickens in that market; but if we found another possible
detection in another market, we assume the risk is much higher and we
need to cull all the chickens in all the markets.
Reporter:
Is there a breakdown in the surveillance? And you've vaccinated all the
chickens in the market and why now you've found virus in the market?
Dr York Chow:
You are talking about two things.
Actually we are very grateful that we have such a strong surveillance that
enables us to detect the virus in the market this time.
You are talking about whether the biosecurity and the vaccination policy of
our poultry are functioning, and that is exactly what the concern is all about.
We cannot tell until we have done all the investigation and check where these
chickens came from, and whether these farms have complied with all our
requirements on vaccination and biosecurity measures.
So, we really have to trace to the source of this virus before we can tell
whether there is any change in the virus.
Reporter: Why genetic sequencing is important?
Dr York Chow: Genetic sequencing is important of course to see whether the
virus has transformed into any new type of virus which has different
pathogenesis. This is the sort of routine tests that we will do if we found any
possible virus in the environment.
Media Myths on H7 Transmission
http://www.recombinomics.com/News/06040803/More_H7_MM.html
Poultry companies, govt agricultural departments and the media tend
to downplay just how transmissible these H7 viruses are. It is true that
most human cases only come down with conjunctivitis but that is not the
point. Some people have ended up in the hospital with respiratory infections,
and there has been one death. Another reason for concern is that recent
studies are showing a tendency towards more adaptation to mammals. With
that adaptation could come a tendency towards increased virulence.
The last but not, least concern is that a co-infection with a more deadly virus
such as H5N1 could benefit H5N1 with the ability to become more transmissible
also.
Despite all the reassuring spin, the fact that contacts of the people that had
been exposed to the virus also were positive is just one more indication of just
how transmissible these viruses are.
Antibody testing is more accurate than PCR testing but takes longer. As
you can see, many cases that were really positive tested negative by PCR
originally.
The case for probable H2H transmission was significantly increased by follow-
up studies on H7 antibodies in the above cases and contacts. Over 1000 cases
were identified and 59% of culler contacts were positive, indicating the
sensitivity of the PCR testing was very low and H2H transmission was very
common.

Human H7N2 Reassortant Sequences Withdrawn from Genbank
http://www.recombinomics.com/News/05280801/H7N2_Pulled.html
We were all wondering why it took over 4 years for the viral sequences to
be released on the Yonkers case. But, now that the research based on those
sequences has come out, the sequences have been withdrawn from Genbank
without explanation. No one knows why.
We might think that finding a bird flu virus capable of hospitalizing a human
in the middle of Yonkers, New York, of all places, with no known contact with
birds, would be a matter of concern after they realized it was efficiently
transmitted in other mammals. We also might think that they would be be willing
to share those sequences after the research finally appeared some four years
later, but we would be wrong.
There is something really wrong with this system. Why produce this research
and then take back the sequence information? They did not even release
the full sequences when they were available, only portions of them.
The world is waiting for this information. There is no time to be wasted when there
is not enough Tamiflu in the world, and no vaccine. What are they thinking?
Their own research is pointing out that another bird flu virus is adapting to mammals.
This research came out in PNAS this week:
