Regional prevalence of mutant alleles in dhfr and dhps. Proportions of isolates with mutations at five positions in dhfr (A16, N51, C59, S108, I164) and dhps (S436, A437, K540E, A581, A613) are shown for all published molecular studies of SP resistance in south-western Asia (including results described here). Data correspond to the publications described in Table 3, with cross-checking via the Molecular Surveyor website of the Worldwide Anti-malarial Resistance Network (WWARN). Allele frequencies are shown as blue = wild-type, red = mutant, white = not assessed.
