Sensitivity of simulated prevalence on the choice of parameter values.

<p>Here we in turn varied the threshold for graduation (A), sensitivity of the diagnostic test (B), specificity of the diagnostic test (C), R₀ (D), recovery rate γ (E), and exogenous rate ν (F). The mean prevalence at 3 years for 1000 simulations is displayed as the parameter is varied, for each of the three countries. Parameters which were not varied were assumed to be as in <a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0000458#pntd-0000458-t002" target="_blank">Table 2</a>.
