Fig 2. Prevalence of HPV16 infections among men who have sex with men.

Fig 2

Age-specific predictions of (A) penile and (B) anal HPV16 infection are derived from 20 natural history models combined with 18 settings of sexual contact structure; predictions from models with latency (see Table 2) are shown in dark green, models without in light green. Observed age-specific proportions among HIV-negative H2M study participants (circles) are given as moving averages for 10-year age groups (11,21), (12,22), etc. Vertical lines reflect 95% binomial confidence intervals for the observed proportions. HPV16, human papillomavirus genotype 16.
