Abstract：Objective To investigate the sources of HIV/AIDS infections through heterosexual transmission in Luzhou City. Methods HIV-infected/AIDS patients involving heterosexual transmission were enrolled for a face-to-face interview in Luzhou City. Demographic characteristics and modes concerning high-risk sexual behavior before HIV diagnosis among the patients were collected to identify the most likely time and venues for their HIV infection. Results Three hundred HIV-infected/AIDS patients through heterosexual transmission were interviewed in Luzhou City. There was a statistically significant difference in the routes of HIV infection between male and female patients(χ2=164.834,P<0.001). Commercial sexual contact was the most common route in male patients (90.8%), followed by sexual contact with a regular partner (5.1%) and casual sexual contact (4.1%). Sexual contact with a regular partner was the prevailing route in female patients (71.9%), followed by commercial sexual contact (17.1%) and casual sexual contact (11.0%). Among the self-reported patients with HIV infection through commercial sexual contact, 25.9% self-reported to have commercial sexual activities in two or more cities, and 25.0% in two or more provinces. About 64.3% self-identified that they were infected with HIV in Luzhou City, and 29.3% thought their HIV infection took place out of their home provinces. Conclusions HIV epidemics caused by heterosexual transmission in Luzhou City are complex and widely affected. It is necessary to continue implementation of the targeted health education and intervention among general population and key affected population.
