Plasmodium malariae (A) and Plasmodium ovale (B) infections identified by photo-induced electron transfer-polymerase chain reaction per month by trial arm in the cohort for the duration of the study. Infections are shown as rapid diagnostic test (RDT)–positive (red) or RDT-negative (gray), and the size of the square denotes the number of infections (small = 1, large = 2). No P. ovale infections were found in the focal mass drug administration arm of the trial.
