August 26 Flu Update
Revere has this blog post that is the most important news of the day. Are St. Jude's, the CDC and NIH seeking an international patent for a vaccine based on Indonesian vaccine. Isn't that what we have been critical of Indonesia for doing?Novavax has a new, novel vaccine that has some encouraging reports, making the company a bunch of headlines this morning.
A new type of bird flu vaccine that uses a mock version of the virus appears to protect people against infection and is safe enough to continue testing, Novavax Inc. said on Tuesday.
One thing I have always worried about in a pandemic is the spectre of mandatory vaccination. See here for people who are wary of even garden variety vaccines.
Sharp has a new air purifier.
Geese shot during hunting season will be testing for bird flu in New York.

August 25 Flu Update
People following the flu virus know about NS1, the influenza protein that is believed to play a key role in infection. Researchers from the University of Texas and Rutgers have done some apparently important work on identifying the structure of NS1.A seminar is being held in Chicago for businesses looking to prepare for a potential pandemic.
The researchers have determined the three-dimensional structure of a site on an influenza A virus protein that binds to one of the human protein targets, thereby suppressing a person's natural defenses to the infection and paving the way for the virus to replicate efficiently. This so-called NS1 virus protein is shared by all influenza A viruses isolated from humans, including avian influenza, or bird flu, and the 1918 pandemic influenza virus.

The message was simple. "It's about being prepared for the first 72 hours after an emergency-situation occurs. We want people to consider how they'll notify their families and where they'll meet," she said.An alert reader shipped this along....did you know that deadly toxins are shipped via Fed Ex? Military leaders are reviewing safety rules and suspending lab activities in the meantime.

A human vaccine from Vietnam is said to be effective.The CDC is collecting pandemic survival stories from the Spanish Flu.
"Complacency is enemy No. 1 when it comes to preparing for another influenza pandemic," Dr. Julie Gerberding, director of the CDC, said in a statement. "These stories, told so eloquently by survivors, family members and friends from past pandemics, serve as a sobering reminder of the devastating impact that influenza can have and reading them is a must for anyone involved in public health preparedness."

August 19 Flu Update
The NIH has more on pneumonia causing most deaths in the 1918 pandemic. This is research by Jeffrey Taubenberger, who is a big star in the 1918 research space. Does this mean 1918 could not have happened in an anti-biotic era?Preparations for diagnosing, treating and preventing bacterial pneumonia should be among highest priorities in influenza pandemic planning, they write. "We are encouraged by the fact that pandemic planners are already considering and implementing some of these actions,” says Dr. Fauci.

August 18 Flu Update
CIDRAP reports on trends in Indonesia's bird flu cases. This is a very revealing piece of work....
Of the 125 patients who were hospitalized, 104 were diagnosed with pneumonia immediately or shortly after admission.
The authors report there were 11 case clusters that involved 28 patients. Infected patients who were not part of clusters were more likely to die, but researchers did not find any differences between cluster patients and noncluster patients in terms of when they presented to a healthcare facility, whether they received oseltamivir, or how soon they received the drug.
Patients with secondary cases were more likely to survive than primary case-patients, and they received antiviral treatment about 3 days earlier than primary case-patients. The investigators acknowledge that secondary cases may have involved other early interventions as well. They also report that patients who had indirect exposure to the virus were more likely to die.

Effect Measure blogs the story we ran yesterday about the antibodies in 1918 flu survivors. (Which is all over the media today, by the way.) Along with some scientific explanation, Revere adds some cogent perspective.
We still don't know how typical these people are. After all, they apparently didn't get sick in 1918 despite being infected and they have a good enough immune system to last into their nineties. Maybe most of us aren't so lucky and have waning immunity with the years. But this is some slick work and now that we have the actual antibodies in sufficient quantity to study we can begin to ask what features of the 1918 virus made it vulnerable. How much of this is transferable to bird flu, the current pandemic worry, is difficult to say. These antibodies didn't protect against or react with H5 flu viruses so they aren't a therapy for bird flu. But understanding the basic science of influenza virus is always a plus.
Debate breaks out on ProMed about whether it should report suspected (not officially confirmed) cases from Indonesia.

August 17 Flu Update
South Korea says it is now bird flu free.Interesting study looked at the blood of 1918 flu survivors. Yes, after all this time, they still have the antibodies. What an amazing thing our immune system is.
This is something that never seems to get resolved. Did the Spanish Flu kill on its own, or through opportunistic bacterial infections (which would help to render the likelihood of a killer pandemic as low in the anti-biotic era.)

Vaccination has been widely employed in Vietnam, to mixed results.FAO is also recommending that Vietnam have private-public cost sharing on vaccination programs. Wonder how that will work with small farmers?

Study on Indonesia shows that 80% of cases are fatal. Oddly, it reaffirms that every anti-virals help, but notes that goal is rarely achieved.Would GPs show up for work during a pandemic? Australia thinks they may not.
Of course, the if pandemic flu broke out in China during the Olympics, it would have huge pandemic potential because everyone would scatter to the four corners of the Earth after the Olympics were over. Here, a reporter from Edmonton looks at that very situation.

ProMed has an interesting story on bird flu in swans which they say merits a close read.
I suspect that they demonstrate why adult swans are found dead. The question is how far can a sick swan fly -- 'sick' is a variable term -- and survive, if it even wished to fly while convalescing from this infection; to appreciate risk this should be recalculated as the prevalence rate of infected flying swans.
