Community Health Worker (CHW) Practice Exam

HIV spreads through specific bodily fluids and activities, not through the air or by a single route. It can be transmitted via infected blood, sexual contact (semen, vaginal fluids, rectal fluids), and from mother to child during pregnancy, delivery, or breastfeeding. Breastfeeding itself can pass the virus from an infected mother to the infant. Airborne transmission is not a route for HIV.

Therefore, the best answer includes blood transmission, sex, and mother-to-child transmission (which covers transmission during pregnancy, birth, and breastfeeding). The other options are incomplete or incorrect because they restrict transmission to only one route or cite an impossible route for HIV spread.
