Fig 3. Estimated annual probability of infection for age-constant FOI Models.

(A) Estimated annual probabilities of infection for EV-A71 and CVA6 using the age- and time- constant FOI models without seroreversion (Model 1, solid intervals) and with seroreversion (Model 2, dashed intervals). (B) Estimated annual probabilities of infection for EV-A71 and CVA6 using the time-varying FOI models without seroreversion (Model 3, continuous lines), and with seroreversion (Model 4, dashed lines). The lines represent the mean posterior estimates, while the shaded areas represent the 95% credible intervals.
