[2011 Sept] Presidential Panel Condemns US Syphilis Study in Guatemala   The Commission confirms that despite knowledge that it was unethical, US government medical scientists PURPOSELY infected  "at least 1,300 who were exposed to the sexually transmitted diseases syphilis, gonorrhea and chancroid" to study the effects of penicillin. At least 83 subjects died."    "They infected soldiers, prostitutes, prisoners and mental patients. More than 5,500 people in all were part of the medical experimentation.  And the presidential panel said government scientists knew they were violating ethical rules."   The research "included infecting prisoners by bringing them prostitutes who were either already carrying the diseases or were purposely infected by the researchers. Doctors also poured bacteria onto wounds they had opened with needles on prisoners’ penises, faces and arms. In some cases, infectious material was injected into their spines, the commission reported."

[2010 Oct] US Apologizes for Criminal Human Experiment  The US government "apologizes" for a criminal human experiment--PHS Sexually Transmitted Disease Inoculation Study, 1946-1948.   The experiment was conducted on 696  Guatemalan mental patients who were INTENTIONALLY infected with gonorrhea and syphilis. Many of those infected were encouraged to pass the infection onto others as part of the study. About one third of those who were infected never got adequate treatment. This inhumane, criminal experiment was conducted by doctors in the US Public Health Service in collaboration with the National Institutes of Health --just as the Tuskeegee Syphillis experiment was.
