(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) An international avian and pandemic flu meeting in Hanoi concluded yesterday, with health ministers and top officials from more than 70 countries agreeing on a set of strategies for responding to future disease threats.
The World Health Organization (WHO) listed a global total of 2,500 confirmed cases of swine influenza H1N1 in 25 countries today. That total included 1,204 cases in Mexico, 896 cases in the United States (yesterday's number), 214 in Canada, 88 in Spain, and 34 in the United Kingdom. The death toll remains at 44, including 42 in Mexico and 2 in the United States. [WHO update 22]
