Short answer

Answer: Sharing food

Step-by-step solution

Review modes of transmission for HIV virus

The HIV virus is generally transmitted through the direct exchange of bodily fluids, such as blood, semen, vaginal fluids, and breast milk. Some common ways for HIV transmission are the sharing of injection needles, sexual contact between individuals without using protection, and in some cases, from an HIV-infected mother to her child during childbirth or breastfeeding. Now, let's examine each given option and determine which is an incorrect way of transmitting HIV.

Analyze option A

Option A states: "sexual contact among homosexual men." Since HIV can be transmitted through sexual contact without using protection, this is indeed a mode of transmission for the virus.

Analyze option B

Option B states: "the sharing of needles by intravenous drug users." Sharing of needles could result in direct exchange of blood, which is an accurate mode of transmission for HIV.

Analyze option C

Option C states: "sexual contact among heterosexuals." Similar to option A, this is also a valid mode of transmission for HIV, as it involves sexual contact without using protection that can lead to an exchange of bodily fluids.

Analyze option D

Option D states: "sharing food." Sharing food is not a mode of transmission for the HIV virus, as it does not involve the direct exchange of bodily fluids, like blood or semen.

Identify the answer

Based on our analysis of each given option, it is determined that option D, "sharing food," is the incorrect mode of transmission for the HIV virus.
