Study design
This was a prospective controlled community intervention trial, quasi-experimental in the sense that residents were assigned to interventions based on sub-county of residence in an arbitrary but non-random fashion. The trial was conducted between October 2016 and June 2019, for a duration of 32 months, and had three assignment arms: MDA + IRS, IRS only, and SOC as the control arm, which included ITNs and case management at facilities with commodity support. SOC interventions were present in all three arms.
