Figure 1From: Population genetic structure of Plasmodium falciparum across a region of diverse endemicity in West AfricaLocation of 8 West African sites sampled for study of P. falciparum population structure, with analysis of 10 microsatellite loci in a total of 268 isolates (sample sizes at each of the sites are given in parentheses). In this region, transmission shows a gradient from low levels in the north to higher levels in the south [5].Back to article page
