Which population is at high risk of getting HIV infection?

Intravenous drug abusers

b) Intravenous drug abusers

Intravenous drug abusers who share needles or other drug paraphernalia are at a higher risk of acquiring HIV infection. This is because the virus can be present in the blood of an infected person, and sharing contaminated needles can facilitate the direct transfer of the virus into the bloodstream of an uninfected person.

It's important to note that while individuals with tuberculosis or autoimmune diseases may have compromised immune systems, they are not inherently at a higher risk of contracting HIV unless they engage in behaviors that expose them to the virus, such as unprotected sex or sharing needles. Similarly, individuals with allergies are not at an increased risk of HIV infection solely based on their allergies.
