What behaviors put people at greater risk for contracting HIV?

The correct answer highlights several high-risk behaviors that significantly increase the likelihood of contracting HIV. Unprotected sex means engaging in sexual activities without using barrier methods, which can allow the transmission of the virus if one partner is infected. Having multiple sexual partners raises the risk of being exposed to someone who is HIV-positive. Additionally, sharing drug needles can transmit HIV directly through contaminated blood, as the virus is present in the blood of an infected person. These behaviors are well-documented by health organizations as primary routes of HIV transmission, emphasizing the importance of practicing safer sex and harm reduction strategies to minimize risk.

In contrast, the other options describe healthy behaviors or practices that are not associated with an increased risk of HIV. Eating unprocessed foods and regular exercise promote overall health and do not influence the transmission of the virus. Consistently using condoms is a protective measure that significantly reduces the risk of HIV transmission, making it a responsible practice in preventing the spread of the virus.
