(CIDRAP News) The deadly H5N1 avian influenza virus is behaving in new and unpredictable ways, a World Health Organization (WHO) spokesman said today.
Shigeru Omi, WHO regional director for the Western Pacific, spoke today in Beijing, according to news service reports. China this week announced an outbreak of H5N1 among domestic geese in a far northwestern province. An earlier outbreak in May killed more than 1,000 migratory birds in China.
