The Joint United Nations Program on HIV/AIDS (UNAIDS), Amnesty International, the Global Network of Sex Work Projects and the Global Network of People Living with HIV/AIDS, have all condemned forced HIV testing actions as infringements on human rights and conflicting with proven public health measures that are successful in preventing HIV transmission. Sex workers in Malawi and Greece have been forced to undergo HIV testing and those who tested HIV-positive were criminalized. Stigmatizing measures discourage HIV-positive people from seeking voluntary and confidential counseling, testing and treatment.
