Abstract

BACKGROUND:

Knowledge of human papillomavirus (HPV) transmission dynamics which has important public health implications for designing HPV vaccination strategies is scarce in undeveloped area.

METHODS:

From May to July 2014, 390 couples were enrolled from general population in Liuzhou, China. Exfoliated cells from male penis/glans penis/coronary sulcus (PGC) and perianal/anal canal (PA) sites and from female vaginal, vulvar, and PA sites were collected biannually for one year.

RESULTS:

The HPV type-specific concordance rate between couples was 15.5% (95% confidence interval [CI]: 8.5, 25.0). For anogenital HPV transmission, male-to-female transmission rates (11.5 per 1000 person-month, 95% CI: 4.3, 30.7) were similar to female-to-male transmission rate (11.3, 95% CI: 5.9, 21.7). The concordance rates between male PGC site and female vaginal, vulvar and PA sites were 20.0%, 21.8% and 14.9%, respectively, which were significantly higher than expected by chance. Infections transmitted from male to female seemed mainly originated from male genital, while for female-to-male transmission, the vagina, vulva and PA sites might be all involved.

CONCLUSION:

Among the heterosexual couples with relatively conserved sexual behavior, anogenital HPV transmission rate for female-to-male is similar to male-to-female. In addition to vagina and vulva, female PA site is also an important reservoir for HPV transmission.
