#6: US Infected Guatemalans With STDs

This was one of the rare cases where the US actually acknowledged this and apologized in 2010. However, it was still an horrible experiment to conduct. The intention was to transmit the STD to prisoners either through intercourse with an infected prostitute or through other means such as; poured syphilis bacteria onto mens’ genitalia and on their forearms and faces. Then they would give them penicillin which had been established as a cure (they wanted to test out to see if penicillin was 100% accurate). However, it has been estimated that as many as 1/3 could have been left untreated.
