    Abstract:
    Human papillomavirus (HPV) infection is the pathogenesis of anogenital cancers and genital warts in both men and women, whereas there is a scarcity of large studies focused on HPV prevalence in different anogenital sites of both sexes in the same population. From May to July 2014, 2,309 men and 2,378 women aged 18-55 were enrolled from communities in Liuzhou, China. Penis/glans penis/coronary sulcus (PGC) and perianal/anal canal (PA) specimens of men, and vaginal (VA), vulvar (VU) and PA specimens of women, were collected and genotyped for HPV. The prevalence of any HPV tested in PGC and PA samples from men and VA, VU and PA samples from women was 10.8%, 3.8%, 14.2%, 13.3% and 8.4%, respectively. The concordance of VA and VU was highest (kappa = 0.74), followed by VU and PA (0.44), VA and PA (0.38) and PGC and PA (0.14). Besides sex behavior, ever having used a towel supplied by a hotel was a risk factor for both external genital and PA HPV infection. Our data indicated that women were more of a major reservoir for oncogenic HPV infection of both genital sites and PA sites than was men. In both sexes, the genital sites were more likely than PA sites to harbor HPV infection. The concordance rates of HPV infection between genital sites and PA infection were poor.
