Plasmodium falciparum multidrug resistance-1 gene (pfmdr1) polymorphisms associate with altered antimalarial susceptibility. Between 2010 and 2018/19, we observed that the prevalence of the wildtype allele N86 and the wildtype combination NYD increased ten-fold (4% versus 40%) and more than two-fold (18% versus 44%), respectively. Haplotypes other than NYD or NFD declined by up to >90%. Our molecular data suggest the pfmdr1 pattern to have shifted towards one associated with artemether-lumefantrine resistance.
