After epic debate, avian flu research sees light of day

Excerpt:

The study, conducted by an international team of researchers led by Kawaoka, a UW-Madison professor of pathobiological sciences and a leading expert on influenza, shows that some viruses now circulating in nature require just four mutations to the hemagglutinin protein, which sits on the virus surface and enables it to bind to host cells, to become an even greater threat to human health. A subset of the mutations identified by the Wisconsin group has, in fact, already been detected in some viruses circulating in poultry flocks in Egypt and parts of Southeast Asia, underscoring the urgency of science-based surveillance, Kawaoka says
