Abstract：Objective To analyze the infection source and characteristics of sexually transmitted HIV/AIDS cases in Wenzhou City, Zhejiang Province during 2017-2019, and to provide a basis for adjustment of AIDS comprehensive prevention and control measures. Methods Newly reported HIV/AIDS cases in Lucheng District and Yongjia County in Wenzhou City from 2017 to 2019 served as the study subjects. Their information about demography, sexual behavior and migration was surveyed and collected, and then their blood samples were detected for initial CD4+ T-lymphocyte count. All the data were collected by Epi Data 3.1software, and analyzed by SAS university edition. Results There were 342 HIV/AIDS cases investigated. Most cases were male, aged between 25 and 59 years, unmarried, with an educational background of junior middle school or below, and migrants. Through judging their infection sources, the proportions of new infection cases and local infection cases were 22.42% and 71.00%, respectively. The new infection cases were found to be higher in the group under 15-24 years old and the unmarried, with the proportions of 33.33% and 31.54%, respectively. The local infection cases were found to be higher in the group aged 60 years and above, teachers/cadres/retirees, and the group with an educational background of college degree or above, with the proportions of 94.74%, 87.80% and 81.43%, respectively. The proportions of new infection cases with non-commercial temporary heterosexual behavior and homosexual behavior with fixed sexual partner were 60.87% and 39.53%, respectively, which were higher than thosein previous infection cases (χ2=3.967, P=0.047; χ2=4.314, P=0.038). The proportion of local infection cases with non-commercial temporary homosexual behavior was 98.26%, which was higher than that in non-local infection cases (P=0.036). Conclusion The sexually transmitted HIV/AIDS cases in Wenzhou City from 2017 to 2019 were mainlyassociated with previous and local infections. We should pay attention to youths, the elderly and highly educated personnel, and enhance interventions on non-commercial temporary sexual behavior.
