H5N1 News: Vietnam Finds New Strains of Bird Flu Virus
A Reuters newswire article, via Yahoo! News, reports that:
Vietnamese scientists have found more variations of bird flu viruses in poultry, adding to the health risk to people if these strains keep circulating, a health official said on Wednesday.
Dong Manh Ha, director of Ho Chi Minh City Regional Animal Health Center, told Reuters a study conducted by the center found new avian influenza strains of the H3 and H4 subtypes in poultry.
Scientists say strains of the H3 and H4 subtypes are capable of causing death in birds but are generally less virulent and spread more slowly than the H5 subtype they fear could trigger a human pandemic.
