Can you get infected by touching someone who does not have AIDS?

Under normal circumstances, contact with individuals who do not have HIV will not lead to infection, as HIV is transmitted only through specific routes. If there has been an unusual exposure, timely testing is recommended. The detailed explanation is as follows:

HIV exists in the bodily fluids of infected individuals, such as blood, semen, and vaginal secretions. Transmission requires three conditions: presence of the virus, a sufficient quantity of virus, and entry into the body through broken skin or mucous membranes. Everyday contact with healthy individuals—such as handshakes, sharing meals, or using the same restroom—does not pose a risk of infection because there is no source of the virus and no transmission route.

If the person contacted is a confirmed HIV-positive individual, infection risk exists only when engaging in high-risk behaviors such as unprotected sexual intercourse, sharing injection needles, or receiving contaminated blood transfusions. Casual contact such as hugging, coughing, or sneezing poses no risk, as the virus cannot penetrate intact skin or spread through the air.

Maintaining a single sexual partner, avoiding needle sharing, and receiving blood transfusions only at正规 medical institutions can effectively prevent infection. In the event of high-risk exposure, seek medical attention promptly for post-exposure prophylaxis (PEP) and undergo regular testing to rule out infection risk.
