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

HIV (Human Immunodeficiency Virus) is primarily transmitted through specific bodily fluids that include blood, semen, vaginal fluids, and breast milk. The correct answer is identified as sneezing, as it is not a recognized method of HIV transmission. HIV is spread when these infectious fluids come into contact with a mucous membrane or an open wound of an uninfected person, typically through activities such as unprotected sex or sharing needles.

While blood, breast milk, and semen are all valid channels for HIV transmission due to the virus's presence in those fluids, sneezing does not transmit the virus because the virus does not survive effectively outside the human body in the way that viruses responsible for respiratory infections do. HIV cannot be transmitted through respiratory droplets, and therefore sneezing does not pose a risk for transmitting HIV. This distinction is critical for understanding how HIV spreads and for educating individuals about prevention methods.
