FIG 2.

Cumulative hazard of malaria (fever or history of fever with any parasitemia) in children who received SMC with DHA-PQ or SP-AQ on three occasions in August, September, and October. A cohort of untreated children were recruited as a control group, at the time the main cohorts received the second round of SMC. The y axis shows the mean number of episodes per child since the start of surveillance. Malaria episodes were detected by passive detection, and at cross-sectional surveys performed just before each round of SMC.
