Question

Quizplus · Accepted Answer

Anal intercourse is the highest risk sexual behavior for spreading HIV infection because the anal mucosa has a higher concentration of immune cells that are more susceptible to the virus. Vaginal intercourse also poses a risk, but it is considered lower risk than anal intercourse because the vaginal mucosa is thicker and has fewer immune cells. Kissing is a low-risk behavior for transmitting HIV because saliva typically does not contain enough of the virus to cause infection.
