The 1968 pandemic was caused by an influenza A (H3N2)
virus comprised of two genes from an avian influenza A
virus, including a new H3 hemagglutinin, but also
contained the N2 neuraminidase from the 1957 H2N2
virus. It was first noted in the United States in
September 1968. The estimated number of deaths was 1
million worldwide and about 100,000 in the United States.
Население Штатов с тех пор увеличилось больше чем вдвое,
так что до гриппа короне расти и расти
