<p>We conducted a mixed method descriptive cross-sectional study and interviewed the stakeholders and operators of the IDSR surveillance system using a structured questionnaire adapted from updated CDC guideline on surveillance system evaluation. Timeliness and completeness were evaluated using the measles case investigation forms (CIF). Cases reported within 72 hours of notification were classified as timely. Properly filled CIFs were classified as complete. A multiple outcome variable was created by categorizing the attribute scores: ≤ 50 (attributes not met) and &gt; 50 (attributes met). Data were analyzed using Microsoft Excel.</p>
