Give me a museum and I'll fill it. (Picasso) Give me a forum ...
From the beginning of time to the 1950's, polio was a horrible disease that could paralyze you (1/200), give you menengitis (1/25), or flu like symptoms that went away (1/4), or be asymptomatic (75/100). Life wasn't shut down before the '60's when widespread vaccinations occurred after being discovered by Salk in 1953. It took several tries to finally eliminate polio in the US until 1979, Europe in 2002, SE Asia in 2014 and is still being fought in Africa. Polio is much worse than Covid-19.
Polio did shut down some areas of the U.S. for periods of time. My mother tells me that when she was young (in the 1930s) schools and factories in her town shut down because of polio for months at a time. She was told she could not leave her yard and if she did her parents would be out in jail.
The 1918 flu also shut down many areas and the cities that shut down had much fewer deaths from the flu.
