There’s no chance of getting or transmitting HIV from closed-mouth or “social” kissing, and you can’t get HIV through saliva.

The only way to know if you have HIV is to get tested. Learn more about getting tested.

There is no chance of getting or transmitting HIV by touching if your body doesn’t touch someone else’s semen, vaginal fluid, or blood because these body fluids can carry HIV.

Learn more about lowering the risk of getting or transmitting HIV during touching.

There is little to no risk of getting or transmitting HIV from cunnilingus. Compared to other types of oral sex, the risk of getting or transmitting HIV from fellatio is higher if the partner receiving oral sex ejaculates in the other partner’s mouth because semen can carry HIV.

Learn more about ways to lower the risk of getting or transmitting HIV, including taking medicines to prevent or treat HIV and using condoms.
