HIV infection is acquired through sexual intercourse with an infected partner; exposure to infected blood and blood products; from an infected mother to the unborn child in the uterus, during delivery, or from breast milk. More than 90% of adults in sub-Saharan Africa acquire HIV infection from unprotected sexual intercourse with infected partners. Transmission of HIV through body fluids other than blood and genital secretions such as CSF, pleural fluid, amniotic fluids etc. is certainly possible. However, to date there are no reported cases of HIV transmission resulting from exposure to saliva, urine or sweat suggesting that the risk of an individual acquiring infection from these body fluids is minimal if any.
