HIV can enter the body through damaged areas in the mucous membranes lining the vagina and the rectum. The mouth also contains mucous membranes, but they do not contain cells that are vulnerable to HIV, such as those present in the vagina and rectum. Saliva contains several proteins and enzymes that serve many different functions, such as beginning the digestion process, assisting in mouth lubrication, and even fighting off germs.
Secretory leukocyte protease inhibitor SLPI is an enzyme present in saliva, mucus, and seminal fluid. Saliva contains much higher concentrations of SLPI than vaginal and rectal fluids.
This may explain why HIV is mostly present in body fluids other than saliva. Body fluids that contain HIV can include:. HIV transmission can occur during anal or vaginal sex without the use of a condom. There have been cases of HIV transmission through oral sex but the risk of this extremely low.
HIV transmission during sex occurs when body fluids containing HIV come into direct contact with mucous membranes or damaged tissue.

Most kinds of physical contact, including holding hands and hugging, do not cause transmission of HIV.
