Which body fluids are known to spread HIV/AIDS?

The correct choice is centered around the specific body fluids that are known to transmit HIV (Human Immunodeficiency Virus), which can lead to AIDS (Acquired Immunodeficiency Syndrome). Vaginal fluid, breast milk, and semen are well-established as fluids that can contain high concentrations of the virus, thus presenting a significant risk for transmission during sexual activity, breastfeeding, and other forms of direct exposure.

Vaginal fluid can harbor HIV and can be transmitted during sexual intercourse. Semen is another key fluid, as it can transmit the virus particularly during unprotected sexual contact with an infected person. Breast milk poses a risk mainly to infants who may be breastfed by an HIV-positive mother, especially in the absence of antiretroviral treatment.

It's important to understand that other options mentioned either contain fluids that are not significant carriers of the virus or do not contain it at all. For instance, blood is a well-known carrier of HIV, but urine, saliva, sweat, feces, and other bodily fluids do not typically transmit the virus under normal circumstances. This specificity highlights the critical fluids that pose a risk, thus providing crucial knowledge for health and safety in cosmetology practices and beyond.
