Which body fluids can transmit the HIV virus, and which ones don ?
Blood, pre-cum, semen, vaginal secretions and breast milk all contain high concentrations of HIV, and all have been linked to transmission of the virus. Saliva, tears, sweat and urine can have the virus in them, but in such small concentrations that nobody has ever been infected through them. However, if any body fluid is visibly contaminated with blood, the risk of transmission exists.
