Nyitray AG, et al. - Researchers designed this study to delineate high-risk anal human papillomavirus (HPV) prevalence, and factors associated with prevalence, among a group of young, primarily black, men who have sex with men (MSM) in Houston, Texas. They identified that increased HPV vaccination efforts would benefit black MSM, given high rates of HPV infection, increased HPV disease, and low vaccination series completion rates.
