Study on the characteristics and influencing factors on non-marital non-commercial heterosexual transmission of HIV/AIDS in Anhui Province, China, 2015–2022

The proportion of newly reported persons with HIV in Anhui Province with a history of NMHC was high, and the proportion of NMNCHC showed an increasing trend year by year. For the female population, special attention should be given to high-risk individuals who have not previously contracted STIs, providing them with relevant sexual education and HIV awareness training. For the male population, focus should be placed on individuals, specifically those with higher education and those who have not previously contracted STIs. Additionally, local HIV prevention and control campaigns and services should be strengthened to enhance residents' awareness of prevention and their self-protection capabilities, thereby reducing the risk of HIV transmission through sexual behavior.
