Estimates of prevalence and IR were based on HPV detection at either anatomical site (glans or shaft).
*IR per 1000 person-months for the first type detected in the glans or shaft.
†Infections with multiple HPV types were considered high-risk if one or more high-risk HPV types were detected. All other multiple infections were considered low-risk types unless they included HPV-X.
HPV, human papillomavirus; IR, incidence rate.
