Which statement about casual contact and HIV transmission is correct?

• A. HIV is transmitted through casual contact.
• B. HIV is transmitted via casual contact only during close, prolonged exposure.
• C. HIV is not transmitted via casual contact.
• D. HIV is transmitted through casual contact via saliva.

Answer: (C)

HIV is not transmitted through casual contact. Transmission happens only when the virus is carried in certain body fluids (blood, semen, vaginal and rectal fluids, breast milk) comes into contact with another person’s blood or mucous membranes, or directly enters the bloodstream. This means everyday interactions like hugging, sharing utensils, kissing on a closed-mouth basis, or being in the same room do not spread HIV. Saliva does not transmit the virus, so casual contact via saliva is not a risk. The real routes are unprotected sex, sharing contaminated needles or syringes, and mother-to-child transmission during pregnancy, birth, or breastfeeding, plus some occupational exposures. Therefore, the statement that HIV is not transmitted via casual contact is the correct understanding.
