The prevalence of measles was 55% in Afar region. Measles vaccination coverage was more than 85% in most of district of the region. But Recurrent here & there measles outbreak was reported. This might be hypothesized that low herd immunity in the community. Expanded programme on immunization is one of systems involved in measles surveillance in Afar region. Thus, the aim of the study was to evaluate performance of measles surveillance systems in the Afarregion.. Descriptive evaluative study was conducted in Afar region from Feb 15-May 30/2017. A total of twenty three (n= 23): one region, three districts, ten health centers and nine health posts were included by purposive sampling technique based on their involvement in and relevance to the measles surveillance system. Data was collected by trained nurses (n= 12) using structured interviewer administered questionnaire adopted from “Centers of Disease Control (CDCs) Updated Guidelines for the Evaluation of Surveillance Systems. Data was analyzed by SPSS version 20 software. The study revealed that the Performance of surveillance systems core activities relatively were 100% at regional level. But, at district and health facility level were still far from the 80% target. Performance of surveillance systems supportive function at health facility levels were still far from the 80% target, but relatively 100% at regional and district level. Timelines & completeness both at regional and district level was low which was still far from the 80% target. So, the system found to be simple and flexible. It is inadequate completeness and timeliness. There were Poor mechanisms of feedback from central to peripheral health system. System has low stability, which led system to be not very useful and not representative. Predictive value positive found to be low. Surveillance system appears to be not meeting its objectives. Hence, the region should expand a web based reporting system.
