Declarations

: The investigators will ensure that this study is conducted in compliance with the current revision of the Declaration of Helsinki. All researchers working on this project must be trained in Good Clinical Practice. The study protocol has been approved by the National Research Ethics Committee of Tanzania on 17 June 2021 (reference NIMR/HQ/R.8a/Vol.IX/3695) and the Oxford Tropical Research Ethics Committee on 2 July 2020 (reference #533-20). Approval for any important protocol modifications will be sought from both ethics committees.Written informed consent was obtained from the head of household during the eligibility assessment and re-affirmed prior to the start of disease surveillance of the children. In addition, assent is obtained from children 10 years of age and older. Participants or parents/guardians have the right to withdraw their child/children from the study at any time. Children reaching 13 years of age will be censored in the analysis. This is a dynamic cohort such that children leaving the study site will be withdrawn, whereas newborn or older children under 13 years joining the household will be invited to participate in the study.
