Having multiple STIs increases the risk for HIV.

Having multiple STIs increases the risk for HIV.

• A. True
• B. False
• C. Not sure
• D. No effect

Answer: (A)

When sexually transmitted infections are present, they often cause inflammation and disruption of the genital or rectal mucosa. This inflammation brings more HIV target cells (like activated CD4+ T cells and macrophages) to the site and weakens the barrier that normally protects against viral entry. Ulcerative STIs, such as herpes simplex or syphilis, create actual openings that HIV can more easily cross. If someone has multiple STIs, these effects can occur at several sites and compound, increasing both the likelihood of HIV crossing the mucosa and the local concentration of HIV in the area. In addition, some STIs can raise HIV shedding in infected individuals, making transmission more likely to occur. So, biological changes from multiple STIs collectively elevate HIV risk beyond having a single infection.
