I heard from a friend that having sexual intercourse with someone who has HIV/AIDS carries a high risk of infection. What is the actual probability of HIV transmission through sexual contact?

Dr. Jiang Weimin
The risk of HIV transmission through sexual contact remains very high—especially during unprotected sex, which almost invariably leads to infection. Moreover, in daily life, open wounds or ulcers on the genitals significantly increase the risk of HIV infection. Therefore, to protect yourself, avoid unsafe sexual practices and maintain personal sexual integrity by refraining from having multiple sexual partners.
