Fig. 2.

P. falciparum migration communities for the Americas region. Each map represents a different stage of country-merging into communities connected by relatively higher levels of infection movements than to the surrounding regions, with community membership shown by color. For instance, the top map shows that the Suriname and French Guiana form a community (colored cyan). The plot in the center shows the overall strength (measured by modularity score) of clustering at different stages of merging countries together into communities. The stage that each map shown represents is identified by the connecting lines.
