Infection with the sexually transmitted human papillomavirus is very bad news with regard to one's risk for sexually contracting HIV, according to a study in the journal AIDS. Researchers report that HPV significantly increases inflammation in the genital and rectal tracts, which in turn brings vulnerable immune system cells close to the surface of the vagina and anus where they can more easily be infected. The body's response to HPV also causes blood vessels and mucosal tissues to become more delicate, which boosts chances for breaks and bleeding that can allow HIV to enter the body. Because HPV is the most common STD in the United States, experts advise sexually active men and women (including HIVers) to be regularly screened for signs of infection and HPV-related lesions and cancers.
