I had to close the other panflu thread as it was way too long, and becoming unreadable. I am starting this one with info on the agenda of this meeting tomorrow in Congress. I am linking to... Read More

I could not pull up the CIDRAP link on this article so you'll have to read this excerpt. This does seem odd. So few bird deaths but so many human cases.
Of 221 patients identified as contacts, 171 may have been exposed in a workplace setting, including patients and staff at two hospitals, the NPHS statement said. At one of the hospitals, 79 patients and staff were offered oseltamivir because of contact with a healthcare worker who was treated for the H7 flu virus. Lyons said in the NPHS statement that the sick staff member was working between May 21 and 23, when she may have been infectious.
At the other hospital, 69 patients and staff were notified because a patient who had the H7N2 illness was recently treated at the facility. Lyons said the patient was discharged on May 18, and after an 8-day incubation period, anyone who was ill would have had symptoms by May 26. "So we are contacting all staff and patients to ensure that they remained well and to reassure them," she said in the statement.
"There may be a bit of complacency when it comes to recognizing the pandemic potential of H7 viruses," Michael Perdue from the World Health Organization (WHO) told the Associated Press (AP) today.
The number of [H7] human cases seems large for the small number of bird deaths, he told the AP. "Unless there's something unusual about the contact with birds, that suggests the virus is finding new ways of getting to humans," he said in the AP report.

This is one of the countries that is most experienced with controlling H5N1. If they are struggling to contain this disease, than it is important to know this.

Jun 1, '07Another death in Indonesia, another 15 yr old girl this time. So many young girls in both this country and Egypt...
Jun 1, '07Vietnam, still trying to get their situation with H5N1 under control:
Thailand worried that these poultry deaths are caused by avian flu:
Jun 1, '07Vietnam reporting a new human case of H5N1, and another two suspected
cases, one of which has already died:
I have not posted anything really on the wild birds of Hong Kong. Let's just say that many of their common birds are infected with avian flu. This is just one example, but there have been many, many others. I think that you could say that H5N1 is endemic in their various species of wild birds. They do seem to test any that are found dead very promptly.
Jun 2, '07Antibodies from H5N1 survivors provide possible treatment:
Quote from www.scidev.net/news/index.cfm?fuseaction=readnews&itemid=3658&language =1The researchers, including doctors from the Hospital for Tropical Diseases in Ho Chi Minh City, Vietnam, isolated antibodies from the blood of human survivors of the H5N1 virus. Studies in mice showed these to be effective at preventing infection and neutralising the virus in those already infected.
The research was published in PLoS Medicine this week (28 May).
Gregory Hartl, communications adviser at the World Health Organization said the study offers a potentially promising new mode for the prevention and treatment of H5N1. "[The antibodies] have the advantage of prolonged duration of activity compared to current antiviral drugs," he told SciDev.Net.

Jun 4, '07UNICEF puts workers on avian flu alert:
Quote from http://www.antiguasun.com/paper/?as=view&sun=485125086506042007&an=490731088706042 007&ac=LocalAs UNICEF's focus is forwarding the rights of children, a World Health Organisation (WHO) study revealed that youth will be the most vulnerable in the event of the spread of the human pandemic influenza. Apparently 90 per cent of people who have been diagnosed with H5N1 avian flu are under the age of 40.
Jun 6, '07Vietnam grapples with H5N1 crisis:
Quote from afludiary.blogspot.com/2007/06/vietnam-grapples-with-h5n1-crisis.htmlA few short months ago Vietnam was the poster child for the successful fight against bird flu. Once the most severely hit country in the world, they had reportedly eliminated human infections for more than a year, and were down to sporadic outbreaks in poultry.
Starting in February, we began to see new outbreaks, followed by a period of quiescence. Over the past six weeks, those outbreaks increased dramatically, and we have two confirmed human cases, and two . . . possibly four . . . suspected cases.
Vietnam steps up human surveillance:
Quote from http://vietnamnews.vnagency.com.vn/showarticle.php?num=01HEA060607The Health Ministry on Monday ordered local authorities in nine bird flu-struck localities to strictly monitor all people showing possible symptoms of the virus.
In an urgent message to the nine localities - out of the country's total 15 provinces and cities that have confirmed outbreaks of the disease since early May - the ministry ordered local authorities to isolate those affected by the deadly H5N1 virus.
Grassroots health agencies have been asked to monitor all those who show symptoms relating to bird flu symptoms such as high fever, cough and difficulty breathing. These patients are to be checked in to local hospitals immediately, not left at home.
Jun 6, '07Indonesian reseachers warn that H5N1 may be becoming more transmissible:
We have been watching for these changes for some time now. This is exactly why it is important for all affected countries to share viral samples.
Quote from http://www.alertnet.org/thenews/newsdesk/JAK214520.htmA microbiologist at the bird flu commission said the suspicions were based on preliminary findings of molecular genetic tests conducted at laboratories in Indonesia.
"Virus samples from poultry cases have increasingly shown a similarity in their amino acid structure to virus samples extracted from humans," Wayan Teguh Wibawan told Reuters.
"This makes it easier for the virus to attach to human receptors," he said, referring to receptor cells lining the human throat and lungs.
For the H5N1 virus to pass easily from bird to human, it would have to be able to readily attach itself to these special cells.
For the moment, because H5N1 is a bird virus, it has evolved to easily attach to these receptors in poultry. Humans have a different type of receptor site, making it harder for people to become infected.
Wayan said he had spotted "gradual changes" in the virus sample he receives every month...
Lo Wing-lok, an infectious disease expert in Hong Kong, said changes such as these demonstrated how important it was for Jakarta to share virus samples.
"If there is such a change, it would not only mean that the virus can jump more easily from bird to man, but from human to human, too."
