Ethics approval and consent to participate
: The study protocol received ethical approval from the KEMRI’s Scientific Steering Committee and the Ethics Review Committee (SSC No. 2206). Additional approval was provided by the appropriate county-level health and education authorities, who were briefed appropriately about the surveys. At the school level, parental consent was based on passive, opt-out consent rather than written opt-in consent due to the low risk and routine nature of the study procedure. Individual assent was obtained from each child before participation in the surveys.
