Age‐Specific Prevalence of Anal Human Papillomavirus Infection in HIV‐Negative Sexually Active Men Who Have Sex with Men: The EXPLORE Study

Abstract

Urban, HIV-negative MSM have a stable, high prevalence of anal HPV infection across all age groups. These results differ substantially from the epidemiologic profile of cervical HPV infection in women. This may reflect differences between these populations with respect to the number of new sex partners after the age of 30 and may explain the high incidence of anal cancer in MSM.
