Avian Flu Diary: H2N2: Everything Old Is Flu Again – “This was a flu that put me and my classmates down for an average of 3 to 4 weeks. 10,000 died in LA County. It came around for a second round in 1958-1959 and was called Hong Kong Flu.”

it was 60 years ago this summer when the first U.S. pandemic H2N2 cases were reported, with the initial wave eventually peaking in October.   Dubbed the `Asian Flu’, H2N2 was the first subtype change in seasonal flu in nearly 4 decades, and while milder than the 1918 H1N1 pandemic, it still claimed 70,000 lives in the United States (at a time when the U.S. population was 45% lower than today).
