Which of the following is NOT a mode of HIV transmission?

The correct answer highlights the fact that HIV is not transmitted through the inhalation of droplets. Unlike viruses that are spread via respiratory droplets, such as influenza or the common cold, HIV is primarily transmitted through specific bodily fluids like blood, semen, vaginal fluids, rectal fluids, and breast milk. This mode of transmission occurs through behaviors such as sharing needles, unprotected sexual contact, and vertical transmission from mother to child during childbirth or breastfeeding. Therefore, the inhalation of droplets is not a recognized or effective mode of HIV transmission, making it the correct response. Understanding the specific transmission routes of HIV is crucial for prevention efforts and public health education.
