Testing indoor residual spraying coverage targets for malaria control, Bioko, Equatorial Guinea

Résumé fourni par la source

Objective: To test 50% indoor residual spraying coverage (percentage of households sprayed) for non-inferiority against the recommended 80% coverage for malaria control. Methods: infection between baseline and post-intervention using difference-in-differences analysis within a survey-weighted binomial generalized linear model. Given differences between the arms at baseline, we adjusted the model for indoor residual spraying coverage at baseline. Findings: infection was no greater in the intervention arm than in the control arm (odds ratio: 0.89; 95% CI: 0.58-1.36), with the upper CI being lower than the non-inferiority margin of 1.43. Conclusion: There was no evidence that 50% coverage was inferior in preventing malaria, which supports the use of this target in settings where this level makes indoor residual spraying feasible by increasing the cost-effectiveness and equity of the intervention.
