In addition, several Asian countries continued to report widespread outbreaks of avian influenza A (H5N1) among poultry; in Vietnam, Thailand, and Cambodia, these outbreaks were associated with severe illnesses and deaths among humans. In the United States, the 2004-05 influenza season peaked in February, was moderate, and was associated predominantly with influenza A (H3N2) viruses.
