It wasn’t common sense at the time. Germ theory wouldn’t exist for another 20 years after Semmelweis’s discovery. His idea of “corpse particles that might turn a living person into a corpse after contact” seemed superstitious and crazy at the time. It was only after germ theory that we learned that these “corpse particles” were in fact germs.
