1957 An H2N2 virus causes the "Asian" flu pandemic, completely displacing the H1N1 viruses that have been circulating in humans since 1918. The pandemic is fairly mild, killing 1 to 1.5 million people worldwide.
1968-1969 An H3N2 virus causes the "Hong Kong" flu pandemic, which is even milder than the Asian flu, killing an estimated 0.75 million to 1 million people worldwide.
