Distribution of malaria parasites encoding the PfCRT K76T mutation in the DRC. This map displays single surveys that analyzed the PfCRT K76T (a molecular marker of P. falciparum chloroquine resistance). Unshaded areas represent the country’s provinces, where parasites potentially carrying a PfCRT K76T mutation have been surveyed (i.e., Haut-Katanga: 3; Kinshasa:10; Kwilu: 13; Lualaba: 15; Maniema: 17; Nord-Kivu: 19; Nord-Ubangi: 20; Sud-Kivu: 22; Tshopo: 25; and Tshuapa: 26). Circles represent surveys from different locations with a diameter proportional to the sample size of parasites that have been successfully genotyped on the codon-position likely encoding the PfCRT K76T mutation. The color palette reflects the relative frequency of the PfCRT K76T parasites during individual surveys
