Chinanwes, Beijing, November 30 – According to the research of China Disease Prevention and Control Center (CDPCC), the origin of AIDS in China should be traced to the 146 drug abusers found in Yunnan Province in 1989.   In 1989, 146 AIDS infected persons were found in a prefecture in Yunnan Province, all being drug abusers. In 2006, there were more than 20,000 HIV-infected persons in that particular prefecture, taking up 2% of its total population. By then the disease had already spread to ordinary people of various trades. 1% of the infected persons were pregnant women.   The research of the CDPCC was meant to find the subtype of the virus, and most of the virus found on HIV-infected drug abusers belonged to the same subtype that originated from Thailand, which were found on the 146 drug abusers mentioned above. The virus found on HIV-infected gays had a lot in common with the virus found on their counterparts in Western countries.
