AIDS/HIV "Patient Zero" Gaƫtan Dugas reportedly used to have unprotected sex with people and then tell them that he was dying from "gay cancer" and that they would probably get it as well. Nowadays a number of countries require HIV infected individuals to disclose their infected status to their sex partners, and people who fail to disclose their infected status may face criminal prosecution for sexual assault or for murder.
The case of one such willful transmitter of HIV, 33-year-old Nushawn Williams is up in court. Williams has served 12 years for statutory rape and reckless endangerment and the government is seeking to keep him locked up indefinitely. Williams boasted of having had sex with up to 300 woman prior to his arrest.
