Has avian flu mutated again? 

There are several disturbing reports coming out of China about human cases of avian flue that don't appear to be connected with outbreaks of the bird-to-bird H5N1 flu. This raises the spectre of asymptomatic avian flu in chickens. To put it mildly, this would not be good.
If we are producing, either through vaccine boo-boos or via natural selection (or both) an H5N1 virus that no longer causes chickens to die in staggering numbers but still continues to shed H5N1 virus, now that is scary news.

So what if, suddenly, we have lost our most important sentinels in the fight against pandemic H5N1? What if the virus has not changed, but the conditions for infection have? I am saying that if it is true that we have asymptomatic fowl in China and in other parts of Asia, and possibly Egypt, and as a result it is becoming easier for humans to get infected simply because fowl are not doing their duty and dying to warn us, then perhaps it is time to reassess that threat level once again.

When you lose a major source of intelligence when fighting a deadly foe, what do you do? When intelligence experts lose their eyes and ears, they ratchet up the threat level to compensate while they regroup and re-establish their eyes and ears.

I thought this was very interesting, well thoughtout and well written. I have posted this on Fluwiki. I hope you don't mind that I have shared it everyone there.

Thanks, but note that it's not my article - I was just citing it.
