A cross-sectional design was used within affected villages in DSA. We interviewed guardians of deceased, health staff, reviewed clinical notes of reported deaths, and interviewed. A suspected case was defined as any child with either fever, cough, coryza and conjunctivitis, with maculopapular rash in DSA from March 04-19 2022. We searched for suspected cases in the community, took their blood samples for testing, and generated a line-list of socio-demographic variables, symptoms, laboratory results and measles vaccination status.  We conducted descriptive analysis and estimated proportions.
