RECRUITMENT, TYPHOID
Field Research Assistants (FRAs) will survey all households in the study area to identify individuals listed in the VDSS and those that may have migrated in or out. They will then approach individuals between the ages of 1 and 30 years for informed consent, and those who consent and do not plan to leave the study area within the next 2 years will be recruited. We will exclude those who have medical conditions that would prevent them from complying with our study’s requirements, which include follow-ups and investigations during illness. A monthly follow-up will be conducted for all participants to check for any changes in residence. A ‘mop-up’ recruitment drive 6 months after the initial process will recruit new migrants into the area and those that are newly age eligible.FRAs will also collect baseline data from participants after enrolment, which includes socio-demographic details, typhoid vaccination history, healthcare facility preferences, etc.
