In my lifetime, there was another deadly flu epidemic in the United States. The flu spread from Hong Kong to the United States, arriving December 1968 and peaking a year later. It ultimately killed 100,000 people in the U.S., mostly over the age of 65, and one million worldwide.
Lifespan in the US in those days was 70 whereas it is 78 today. Population was 200 million as compared with 328 million today. It was also a healthier population with low obesity. If it would be possible to extrapolate the death data based on population and demographics, we might be looking at a quarter million deaths today from this virus. So in terms of lethality, it was as deadly and scary as COVID-19 if not more so, though we shall have to wait to see.
“In 1968/69,” says Nathaniel L. Moir in National Interest, “the H3N2 pandemic killed more individuals in the U.S. than the combined total number of American fatalities during both the Vietnam and Korean Wars.”
And this happened in the lifetimes of every American over 52 years of age.
