Abstract
Background: An estimated 10 million cases and 164,000 deaths from measles occur worldwide each year. On 25 September 2013 Welayita Zonal health department reported suspected measles outbreak. We investigated to verify the existence of the outbreak, identifypossible risk factors and recommend control measures. Method: We define a cases as any person with fever and rash (maculopapular) with any cough, coryza or conjunctivitis living in the affected communities from September 25 to October 30, 2013. We reviewed medical records of patient and active cases searched in the affected communities. Questionnaires were administered to care givers of 40 cases and 80 controls to obtain health and immunization status through immunization cards and/or care givers recall. Results: During the study period we identified 168 suspected cases and without death report. (AR=2.21/1000). The median age was 6 years (range 3 months to 18 years). 40% of the cases were under 5, followed by 27% of 5-9 years. The administrative coverage 98%. We compared 40 cases to 80 controls with median age 5.5 years(3 months-24 years) and found that prior vaccination (odds ratio (OR) =0.15, 95% confidence interval (CI): 0.06-0.36) and knowledge of measles transmission (OR= 0.13, 95%CI: 0.05-0.31) were protective of disease and recent travel to areas with active measles cases (OR=3.80, 95%CI: (1.53-9.74) were associated with higher rates of disease. Among five samples tested three positive for measles specific IgM. Conclusion: Low measles immunization, poor knowledge of transmission of measles, and recent travel to areas with active measles cases and accumulation of susptible groups in under 5 years age may be responsible for this epidemic. We recommend to improve routine and SIAs immunization to highly affected communities.
