Genetic Structure of Plasmodium falciparum and Elimination of Malaria, Comoros Archipelago
Figure 3. Relationship between geographic and genetic distances for each pair of Comoros islands (top) and between mean percentage of travelers among sampled patients and genetic distance for each pair of Comoros islands (bottom). Genetic distances were calculated as (FST/1 – FST ), where FST is the Wright F statistic. Mean percentage of travelers was calculated from the total number of sampled patients in one site (NA) with history of recent arrival from another site (NB) by using the equation ([NB→A/NA] + [NA→B/NB])/2; data in Table 1. GC, Grande Comore; MOH, Moheli; ANJ, Anjouan; MAY, Mayotte; Ln, logarithmically transformed.
