1. Quantitative surveys: All data will be analysed on the basis of intention-to-treat, that is, community residents and school children taking part in the final surveys will be classified as participating in the intervention or control according to the randomization assignment of the cluster they were surveyed in, regardless of whether they (or their children) received the intervention or not. The primary outcome is prevalence of asexual parasitaemia in the community surveys. Prevalence of asexual parasitaemia in the school surveys and EIR are secondary outcome measures. An individual-level approach to the analysis will be used due to the large number of clusters per arm.
