than 62 years, and they had all lived through three viral pandemics in a single lifetime: 1957–1959 (H2N2), 1968–1970 (H3N2), and 2009 (H1N1).[81] The best reconstruction of the total mortality for the 1957–1959 pandemic was 38/100,000 (1.1 million deaths; global population 2.87 billion), the 1968–1970 pandemic had a mortality of 28/100,000 (1 million deaths; global population 3.55 billion), while the 2009 event had low virulence and mortality no higher than 3/100,000 (about 200,000 deaths; global population 6.87 billion).[82]
