Methods: A suspect case was defined as any resident of Chadibe with generalized rash and fever with cough, coryza or conjunctivitis from January 1, 2023, to February 20, 2023.  A confirmed case was a suspect case that tested positive for measles IgM antibody on enzyme linked immunosorbent assay. We interviewed caregivers, patients and reviewed medical records. We collected case-patient’s demographic, clinical, and exposure history. Blood samples were obtained from all suspected cases and analyzed at national health laboratory, Gaborone. We calculated summary statistics, frequencies, and proportions. We conducted active case search and an assessment for measles reactive mass vaccination in the community.
