- Weeks represents epidemiological weeks. I: Incidence of uncomplicated malaria cases per 100 people by SMC cycle, the denominator was calculated according to estimated percentage of each age group (18.74% under five, 25.52% 5–14 years), total population was estimated to be 109,435 people. Estimate according to Poisson model (malaria cases ~ SMC cycle standardized by age group). IRR: Incidence rate ratio. Percent reduction: percentage of reduction in malaria incidence compare to period 0. *: p-value < 0.001
