We conducted a records review using a case definition of a suspected case, as any child less than five years admitted to Kilifi county hospital from January 2017 – December 2021 for treatment for diarrhea while a confirmed case was a suspected case with an enzyme-linked immunoassay detection of Rota-virus in the stool. We collected sociodemographic and clinical information. We used standard CDC MMWR guidelines for the evaluation of public health surveillance. We developed a questionnaire and conducted a face-to-face interview to evaluate the system attributes, and summarized data using descriptive statistics.
