Per a court order, HHS is required to restore this website as of 11:59PM ET, February 14, 2025. Any information on this page promoting gender ideology is extremely inaccurate and disconnected from the immutable biological reality that there are two sexes, male and female. The Trump Administration rejects gender ideology and condemns the harms it causes to children, by promoting their chemical and surgical mutilation, and to women, by depriving them of their dignity, safety, well-being, and opportunities. This page does not reflect biological reality and therefore the Administration and this Department rejects it.

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.
