HIV transmission depends on contact with specific body fluids and routes. HIV is spread through blood, semen, vaginal and rectal fluids, and breast milk, most often during unprotected sex, sharing needles, or from mother to child. The other viruses spread through different pathways: influenza mainly via respiratory droplets, while Hepatitis A and Norovirus spread mainly through the fecal-oral route, such as contaminated food or water or surfaces. Because only HIV involves transmission through those particular fluids and routes, it is the correct choice.
