Fig. 3.

The results of a model structured by access to healthcare, where cases are less likely to be detected in one group because of poor access to testing and diagnosis. The red line illustrates a scenario where control measures are equally effective for both groups. The blue line shows a scenario where control measures do not reduce transmission rates for the group with poor access to healthcare, eventually leading to an outbreak in both populations. Pale lines show the corresponding daily number of new exposures. Results are averaged over 500 independent, identically initialized realizations of the stochastic process.
