<p>We conducted 1:2 unmatched case-control studies in the Ebinat district, Northwest Ethiopia, 2021. We recruited all cases (55) found in the line list and 110 neighborhood controls. Cases are those either suspected or laboratory-confirmed or epidemiologically linked to confirmed cases and identified by case search and controls were selected randomly from neighbors of cases. We used a structured questionnaire prepared and loaded to Epicollect5. Data were cleaned in Excel and exported to SPSS version 21 for analysis. Variables in the bivariable model at p-value ≤ 0.20 were entered into the multivariable model, and p-value ≤ 0.05 were identified as statistically significant risk factors.&nbsp;</p>
