Somehow I missed this when Dr. Vincent Racaniello posted it on how virology blog on March 1: Influenza H5N1 is not lethal in ferrets after airborne transmission. It's a summary of Fouchier's experiments and the recent confusion over whether his mutant H5N1 is as lethal as first described.
It's much clearer than most of the news reports I've read. Racaniello sees the contradiction between what Fouchier was reported to have said in Malta last September and what he said in Washington last month. Clearly we haven't heard the last word in this debate.
