Antiseptic cleanliness campaign of 1920s

“What Americans could not foresee was that their antiseptic revolution brought risks as well as rewards. As the nation cleaned up, new problems arose. There was now a smaller chance that people would come into contact with dangerous microbes early in life, when the infection was milder and maternal antibodies offered temporary protection. In the case of polio, the result would be more frequent outbreaks and a wider range of victims. Franklin Roosevelt was no longer alone” (Oshinsky II, 49-50).
