Figure 3From: Estimating age-dependent per-encounter chlamydia trachomatis acquisition risk via a Markov-based state-transition modelState transition diagram of the time-varying Markov model that captures the disease dynamics with first-time chlamydial infection, curing, and repeated infection. Note that the risks of chlamydial infection for the first time and repeated infection are different; and the sexual behaviors before and after the first-time infection are different as well.Back to article page
