Both public security and health authorities on Wednesday refuted a rumor claiming that a large group of HIV/AIDS carriers had infiltrated large cities and intended to transmit the virus by contaminating food sources.
The rumor, that went viral, claimed that some 20,000 HIV-positive sufferers from the Xinjiang Uyghur Autonomous Region had gone to major cities across the country and laced restaurant food with their blood.
It said those attackers were incited by separatists and terrorists, and warned people to not eat Xinjiang food.
"The Ministry of Public Security and the Ministry of Health (MOH) have confirmed the threat. Several people in Henan Province have been infected," the rumor claimed.
The MOH rebutted the rumor Wednesday, saying that the virus can be transmitted only through blood, sexual contact and pregnancy.
