What is the likelihood of a male contracting HIV after having?
The risk is .1 to 1%. A risk of 1% would mean that one infection can occur if 100 negative people have sex with someone who is positive. It should not be misinterpreted in a way that a person needs to be exposed 100 times to catch the infection. The percentage of contact infectivity of HIV from sexual transmission varies depending on sexual activity. Anal intercourse carries a higher transmission probability (0.5%) than penile-vaginal intercourse (0.1%) and male-to-female transmission is more likely than female-to-male transmission. Chances of HIV transmission through Oral Sex is .01% only. Hope this helps!
