(CIDRAP News) – The first of two controversial H5N1 avian influenza studies to see print suggests that just four mutations in one of the virus's surface proteins may be enough to equip it to spread among mammals, but the findings are freighted with qualifiers.

(CIDRAP News) – In a set of articles published today in Nature, influenza experts say global flu surveillance—especially in poultry and swine—is sorely lacking and needs a major overhaul to make it more sustained, timely, and representative.
