Genotyping using markers sequentially at both study sites. Subjects with recurrent parasitaemia in Kanungu and Apac had samples genotyped in a stepwise fashion in the order shown. A new infection was defined as no alleles matching in samples taken on the day of treatment and the day of recurrent parasitaemia. A subject not classified as a new infection by one marker was then genotyped sequentially with the next marker. Those not classified as having a new infection after being genotyped by all three markers were classified as having a recrudescence, as long as genotyping was successful for at least one marker.
