Results of changing operational strategy for mass test and treat using artemether-lumefantrine. Change (%) in the simulated mean parasite prevalence compared to the simulated mean parasite prevalence measured 1 year after implementation of the existing intervention strategy, as a result of varying the operational strategy of the intervention. Categories represented in the columns include the proportion of the population reached by the campaign (coverage), the number of days between screen and treat rounds (time between rounds), the ages reached by the intervention (target ages), and varying the anti-malarial drug used in the campaign (change drug to DHAP). The existing strategy consists of three rounds of mass test and treat with AL covering 40 % per round of all ages in the population with 60 days between treatment rounds. The rows represent results stratified by the pre-intervention mean parasite prevalence in the population as measured by RDT. Centre solid lines represent the simulated median value, blue boxes represent the inter-quartile range, and capped bars represent the upper and lower adjacent values for simulated results using an ensemble of 14 model variants and three random seeds
