Why polio is the most spreading disease during the great depression?

Answer 1

Probably because there was no vaccine for polio until the 1950s. I remember getting my shot at school from the bulk processor they used to call school clinic. I don't know what caused polio, and to be honest I would have thought that something like Ricketts from a lack of nourishing food and milk would have been more a 1930s thing. I also read a lot about kids from the dustbowl states literally filling their lungs with dirt and dropping dead where they stood from it. I'm sure there was plenty of misery, and polio was probably only a part of it. Phil
