An apology was issued for the experiment conducted by United States public health researchers in Guatemala between 1946 and 1948.
The United States purposely infected 1500 people with sexually transmitted diseases to study the effects of penicillin. Loyal soldiers, uneducated prostitutes, unwilling prisoners, and even the unaware mentally ill were infected with gonorrhea and or syphilis that destroyed their internal organs while they died in unbearable pain.
Prostitutes were instructed by US doctors implementing the experiment to have sex with unwilling prisoners and loyal Guatemalan soldiers.
Some of the patients were allowed to die in agony without morphine, so they could be cut opened and their internal organs could be studied through biopsy. Victims that didn't get infected through prostitutes were later injected in their spinal cords with the bacterial untill they died and their bodies prepared for biopsy. It was the same types of experiments that the Nazis performed on Jewish children.
The experiment were kept secret to prevent retaliation. This horrific situation came to light this year after Wellesley College professor Susan Riverbee came across some archived documents. She began to reviewing the information and found the experiment was led by controversial US public health doctor John Cutler who injected water into unsuspecting African American men who were denied proper medical attention while they died a horrific death filled with pain and agony.
