Declan Butler, my current favorite science journalist, has updated his avian flu outbreak maps and added a network link. He says:
I'm getting the entire outbreak database soon, which is much richer in detail as to sizes of outbreaks etc, which I can extrude [from] the maps, so the who thing should be substantially better soon.
And avian flu is a story that really needs good science journalism. Systemic health risks are very hard to understand for people without a good command of statistics.
Examples of health scare stories that were widely mispereived: When West Nile reached the New York area, Westchester moms panicked and for several weeks of glorious Indian Summer, wouldn't allow their kids to play outside. The real health risk in yards like mine was not West Nile, but Lyme Disease. Also, I had a severe lung infection requiring hospitalization just as the anthrax scare was peaking. I knew I didn't have anthrax, but very carefully went to my regular doctor an not to the ER because I was concerned I might be turned away as an anthrax hysteric. (At the time, NYC ERs were alleged to be turning away peole who said they had difficulty breathing.)
Butler has been tracking down the facts of the matter and putting a lot of them into his overlay.
UPDATE: Here is his Connotea Avian Flu links page.
