#10: Guatemala Syphilis Experiments

As you can probably guess from the title of this entry, these experiments went wrong from the very start. Between 1946 and 1948, the United States led an experiment where doctors infected 1,300 individuals with syphilis, chancroid and gonorrhea without consent. The subjects were exposed to pathogens via intercourse with infected sex workers, forced perforations of their spines and by having bacteria poured on their bodies. Of the infected individuals, only about 700 received medical treatment in the form of penicillin, leaving hundreds of people to experience the full force of these horrible diseases. At least 83 individuals died by 1953 as a result of this inhumane experiment.
