Well put.
You might add to that: enduring polio, including the social distancing and school closures employed by many communities to halt the spread and protect their citizens.
Polio epidemics were primarily a summer phenomenon. And one of the reasons was that people who got it often had been swimming in public pools, and it is primarily a disease of the young. When my aunt contracted it in September 1952, the Louisville General Hospital was overrun with cases from all over Kentucky, and the vast majority of those were young people. There were older adults who contracted the disease, and their death rate was a bit lower than those of young adults. Doctors believed, at the time, that fatigue was a factor, that young folks would go like hell all day long, then crash and sleep after that.
I had a mild case compared to my aunt. She was turned into a quadriplegic, and losing most of her ability to exhale. It attacked her back muscles on one side, causing a permanent spine curvature, and using an iron lung and a chest respirator brought their own problems. The constant pace of breathing caused problems with blood chemistry, and periodically she had to be put in the hospital to get it straightened out. She also took phenobarbital nightly to prevent convulsions, and did so until she died in 1997.
I also believe I was the one who spread it to her. She contracted polio about two weeks after my case, and she had stayed with us for a couple of weeks during August 1952. Doctors also believed that one of the reasons for the virulent polio epidemics was the migration from rural areas to cities, starting around 1915. Urbanites had developed the so-called "herd immunity", something the rural folks didn't have. There are those out there who really believe that the Salk and Sabin vaccines weren't effective; that Polio was dying out. However, I know of no one my age who regretted taking the three shots, then the three sugar cubes.
In 1971, the pulmonary department at the University of Louisville medical school sought people who had polio, to extensively measure one's current breathing capacity, and compare that to a "normal" distribution of the population in Louisville; my loss was measured at around 15%. I also had upper body strength loss, and in 1997, I was diagnosed with "Post-Polio Syndrome", a further loss of muscle mass and tone.
While the Salk vaccine was still over a year away, the schools were packed with boomers; our classrooms were crowded until 1959.
