Artemisinin partial resistance, mediated by mutations in the Plasmodium falciparum kelch13 gene (k13), rapidly spread in southeast Asia, undermining the antimalarial effectiveness of artemisinin-based combination therapies. k13 mutations have also arisen in Africa, but their rates of increase are not well characterised. We aimed to quantify the selection of k13 mutations in Africa and compare the selection with that in southeast Asia.
