Objective The present study was designed to understand the status quo and trend of AIDS epidemic in Dali prefecture. Methods The data from AIDS/HIV serological surveillance in Dali prefecture in 2004 were analyzed. Results Serological surveillance was done on 13 961 high-risk population in Dali in 2004, of whom 1222 cases were found to be infected with AIDS/ HIV. The HIV positive detection rate was 0.62% at the sentinel sites for pregnant women, 11.65% at the sentinel sites for drug abusers and 0.68% at the sentinel sites of STD clinics. 77.09% of the victims were infected through blood transmission, 18.49% through sexual transmission and 1.15% through mother-to-baby transmission, with the transmission route unknown in 3.27% of the infected. Young adults accounted for 85.92% of all the infected, with peasants and the unemployed predominantly involved in terms of occupation, constituting 44.76% and 36.99% respectively. Conclusion In recent years, AIDS spreading has become wider and wider in Dali Prefecture, with blood transmission as a predominant route and sexual transmission increasing year by year. HIV infection is found among unlicensed prostitutes in 12 counties/cities of the prefecture. HIV infection is increasing among pregnant women. The epidemic situation of HIV infection in Dali Prefecture must be taken seriously.
