Abstract
Background: Measles is respiratory disease caused by measles virus and spread through droplets of patients. Approximately 20 million people are affected by measles every year worldwide with the highest numbers in Africa. According to World Health Organization’ report 14,100 confirmed cases have been reported from Ethiopia in 2014. According to national guideline on Measles, approximately 15% of vaccinated children at nine months of age fail to seroconvert, and are thus not protected after vaccination. In February 2016, Telo district reported increased number of persons with fever, and generalized maculopapular rash. We investigated to confirm the outbreak, identify risk factors and implement control measures. Methods: We employed 1:2 unmatched case-control study designs. We collected data by interviewing using questionnaire. We interviewed parents behalf of patients & controls whose age was not appropriate for enquiring. We used case definition as per stated in national Measles guideline. We collected specimens and tested at regional laboratory. We analyzed the data using Epi-Info & ArcGIS. Results: Three kebeles were affected. A total of 68 Measles cases, 30 (44%) male and 38 (56%) female identified. All patients were under 15 years and 58(85%) of them were under 5 years of age. Attack Rate was 1.3%, of this 2.5% was among less than one year old, 27 (40%) of patients were not vaccinated with measles. A measles vaccination dropout rate in affected kebeles was high (44, 13 & -23 of the three kebeles). Three Tested samples are all positive for measles (IgM). Travel history to affected areas (AOR 9.7; 95%CI: 1.7 – 55) and unvaccinated (AOR 4.4; 95%CI: 1.6 – 11.6) were statistically significantly associated risk factors for the infection and age group greater than five years was protective factor(AOR=0.18, 95%CI: 0.05 – 0.66). Conclusion: This investigation confirmed an outbreak of measles and unvaccinated against measles and travel history to affected area were significant risk factors for contracting measles. We recommended supplementary immunization and strengthening the routine vaccination.
