MALARIA
The malaria incidence rate was 3.0 and 38.8 per 100 person-months in the intervention and control groups, respectively. In the intervention areas 90.0% (361/400) of children did not experience any malaria episodes during the study period, compared to 15% (29/200) in the control area. The incidence rate ratio was 0.078 (95% CI 0.063–0.096), which corresponds to a protective effectiveness of 92% (95% CI 90.0–94.0) among children in the intervention area.
