43. Is there a 100% effective way to prevent sexual transmission of HIV?

The only 100% effective way to prevent sexual transmission of HIV is through abstinence – avoiding all vaginal, anal, and oral sex. Using a latex male condom

or a female condom can greatly reduce, but not entirely eliminate, the risk of HIV

transmission (see questions 44-46). However, abstinence is the only method to

completely eliminate the possibility of sexual transmission of HIV.
