Question

Quizplus · Accepted Answer

When drug users share needles, there is a risk of HIV transmission because the needles may be contaminated with blood that contains the virus. HIV can survive outside of the body for a short period of time in bodily fluids, such as blood. Therefore, if a person shares a contaminated needle, they could also be sharing the virus. Additionally, drug users may be more likely to engage in risky behaviors, such as having unprotected sex, which could also lead to HIV transmission.
