Strong C, et al. - The prevalence of and factors associated with anogenital human papillomavirus (HPV) infection among men who have sex with men (MSM) were investigated in Taiwan. From the community and social media, 253 MSM aged 20 years or older were recruited and screened for HPV infection to detect 37 genotypes. Of these, 87 % were below 35 years of age. They observed the prevalence of any tested HPV type of 29.4% at the anal site and 11% at the penile site. Infection with any of the 9-valent vaccine HPV types was evident in one-quarter of MSM. They detected anal HPV in association with having three or more receptive anal sex partners in the past year and having older sex partners. These data may assist in calculating the reproductive rate for HPV transmission in a low-risk community sample and cost-effectiveness to include men in HPV vaccination policies.
