(A) The prevalence of <i>C. trachomatis</i> for increasing numbers of notified partners, in order of their recency. (B) The prevalence of <i>C. trachomatis</i> for different partner notification periods. There is a 50% probability that each notified partner will be tested and successfully treated. For each strategy, means of 100 simulation runs are shown. Standard errors are small and omitted for better visibility.
