Projected emergence of artemisinin resistance in Africa. The estimated percentage of P. falciparum infections in African countries that contain ‘mutants’ (K13 mutations conferring the slow clearing phenotypes) as the most prevalent within-host strain; 2020, 2025 and 2030. Estimates are based on the prevalence of malaria reported in the Malaria Atlas Project [28, 29] in 2007 before the large scale-up of artemisinin-based combination therapy across Africa [38, 39]
