Fig. 2From: Combining next-generation indoor residual spraying and drug-based malaria control strategies: observational evidence of a combined effect in MaliMonthly incidence of confirmed malaria cases in intervention districts relative to the control districts. Epidemiologic curves for each intervention district are overlaid on the contemporary curves from the three neighboring districts that received neither intervention in 2014 (control districts; in blue). The area of the tan curves shows the difference between the incidence rates observed in each intervention district relative to the control districts, illustrating the overall impact of the interventions on rapid diagnostic test confirmed (RDT +) malaria case rates. Results are presented for (a) the total all-ages population and (b) the population under age 5Back to article page
