Syphilis is a terrible disease. After being infected, it may lie dormant for decades, then restart and destroy the main human organs. However, 60 years ago, 1,500 people (mainly vulnerable people) in Guatemala contracted syphilis without their knowledge.
The reason is that an American scientist, Dr. John Cutler, has always tested the effect of penicillin on STDs. At least one patient died during the study. At that time, although the scientists were authorized by the authorities, they did not seek the consent of the parties. Only a few years ago, Obama apologized to the people in Guatemala for this incident.
Some Senate called it the “darkest moment” in American history. The doctor first infected the prostitutes with gonorrhea or syphilis, and then allowed them to have sex with soldiers or prisoners without wearing condoms, but even that did not make many men sick. Later, the doctors simply infected soldiers, prisoners, and mental patients.
