I remember that flu well. The only flu that made me seriously ill. It was a hybrid, a bird flu, the ones that are the most dangerous to people with a strong immune system.
1957-1958 Pandemic (H2N2 virus)
“In February 1957, a new influenza A (H2N2) virus emerged in East Asia, triggering a pandemic (“Asian Flu”). This H2N2 virus was comprised of three different genes from an H2N2 virus that originated from an avian influenza A virus, including the H2 hemagglutinin and the N2 neuraminidase genes. It was first reported in Singapore in February 1957, Hong Kong in April 1957, and in coastal cities in the United States in summer 1957. The estimated number of deaths was 1.1 million worldwide and 116,000 in the United States.”
The Hong Kong flu in 1968-69 was also bad (I remember being very ill at age 6). Yet nobody wore masks, the media basically ignored it, we had Woodstock and landed on the Moon.
I also remember the H2N2 Flu. It deciminated the effectiveness of Malstrom AFB.
Most of the infected personnel were sent to barracks because we didn’t have enough beds in the hospital.
I personally inoculated over 1,000 AF personnel during that time period.
