Abstract
Background: Measles is an extremely contagious and remains a common disease and major contributor to child-mortality worldwide and kills approximately 1-3 of every 1000 infected individuals. An estimated 10 million cases and 164,000 deaths from measles occur worldwide each year. On January 17/2014 West Gojam zone, Amhara region reported suspected measles cases from Yilmana Denssa district. As part of it West Gojam zone has been reporting remarkable measles cases started On December 5/2013. An investigation was conducted to identify the cause of the outbreak and to undertake appropriate prevention and control interventions
Method: Unmatched Case control study design was used to investigate the outbreak and identify risk factors for the occurrences of the outbreak. We used a structured questionnaire to solicit information from cases and controls. Analysis was made using Epi Info version 7.1.3.3 and Microsoft Excel.
Result:Totally 292 cases and 5 deaths (4 facility and 1 community deaths) were identified. Sample was taken for seven cases and all of them found to be positive for measles IGM. . Out of 292 total cases 169 (58%) were females. The mean ages 13 years and overall attack rate (AR) of the case was 120/100,000 populations. 92.5% of affected cases were unvaccinated. Exposure to a measles cases was significantly associated with illness (OR= 6.3, CI (1.78-22.73) with p-value 0.001)
Conclusion: Unvaccinated children less than 15 years of age were primarily affected by the outbreak. Most of the cases were unvaccinated. So mass vaccination campaign from 6 months -14 years of age groups should be conducted to stop the transmission.
