Can a person be exposed to HIV by kissing the cheek of an infected person?

HIV is not transmitted through sweat or ordinary skin-to-skin contact, so kissing someone on the cheek does not expose a person to HIV. The best answer is “no, because sweat does not contain the virus.” HIV transmission requires certain body fluids, such as blood, semen, vaginal fluids, or breast milk, to enter the body through a suitable route.
