From March 27 to April 29/2022, a descriptive and 1:2 unmatched case-control study was conducted in the Raso district. There were 85 cases used in total for the descriptive study. 58 cases were chosen by computer-generated simple random approach employing line list as a sampling frame, and 116 controls were analyzed in order to find the factor linked to the outbreak. . Home-to-home searches in the affected kebeles were used to find active cases, and controls were chosen from cases' neighbors. To confirm cases, an IgM test was performed on five serum samples. Cases were defined as anyone who experienced a fever, maculopapular rash, cough, coryza, or conjunctivitis, whereas controls did not have these symptoms. We gathered information using a standardized questionnaire, and cases were described in terms of the person, place, and time they occurred.
