Guatemala syphilis experiments

Human experimentation conducted by US doctors in Guatemala

The Guatemala syphilis experiments were United States-led human experiments conducted in Guatemala from 1946 to 1948. The experiments were led by physician John Charles Cutler, who also participated in the late stages of the Tuskegee syphilis experiment. Doctors infected 1,300 people, including at least 600 soldiers and people from various impoverished groups with syphilis, gonorrhea, and chancroid, without the informed consent of the subjects. Only 700 of them received treatment. In total, 5,500 people were involved in all research experiments, of whom 83 died by the end of 1953, though it is unknown whether or not the injections were responsible for all these deaths. Serology studies continued through 1953 involving the same vulnerable populations in addition to children from state-run schools, an orphanage, and rural towns. However, the intentional infection of patients ended with the original study.
