I was in college when the Hong Kong flu hit here. I remember going to Student Health and being put on an IV drip to re-hydrate. Approximately 100,000 people died in the U.S. from the HK flu, when the total population was only about 200,000,000. I don’t remember any lock downs.
There weren’t any lock downs.
They had “social distancing” I think they called it Woodstock!
