Ebola cases per city in case of intra-country transmission (selected countries). Note: Scenarios showing potential number of cases in each city assume either 10 or 100 cases before detection and initiation of an effective response. In each city, the speed at which an Ebola outbreak was assumed to be brought under control was modeled using one of three control scenarios. These scenarios were either faster, equal or slower than the speed of the control of the Liberian Ebola epidemic, and the estimates adjusted for population density. Cities were allocated to each control scenario based on their country’s World Bank economic classification (see text and Supplemental material for further details). The specific numbers in this figure are shown in Additional file 2 : Appendix S2, Table S7
