(CIDRAP News) – The world registered fewer human infections with H5N1 avian influenza in 2012, but the fatality rate was a little higher than in previous years, the World Health Organization (WHO) noted in a recent review of the year's data.
(CIDRAP News) – Researchers report that swine and human influenza A/H3N2 viruses associated with an Ohio county fair held in July make a nearly perfect genetic match, suggesting that there is almost no biological barrier to prevent such viruses from passing between humans and pigs.
