Abstract
Introduction:
Measles is a leading vaccine preventable contagious disease caused by a virus genus Morbilli.
According to the official report, an outbreak of measles is occurring throughout the regions of
Ethiopia. Didesa was one of the measles outbreak affected woreda in Oromia Region in 2014.
We conducted this study to determine the magnitude of morbidity and mortality due to measles
infection and risk factors associated with outbreak.
Methods:
We used descriptive cross-sectional followed by unmatched case-control study, 50 cases with
100 controls. We collected the data using measles line lists, observation of cold chain, key
informant interviews and using structured questionnaires.
Results:
A total of 84 measles cases with no death were reported during the outbreak. The outbreak was
confirmed for measles IgM antibody. The index case was in Mede-Misoma Kebele. Age specific
attack rate was higher in age groups of 5-14 year (9.9/1000person). The overall attack rate was
5.8/1000person. Seventy percent of the cases were unvaccinated. Being vaccinated and having
awareness on the mode of transmission for measles infection were protective factor for
developing the disease and statically significant with OR 0.13 [95% CI = 0.05-0.37] and OR 0.33
[95%= 0.12-0.89] respectively. Case management, active case searching and health education
was conducted during the outbreak.
Recommendations:
Improved routine and campaign measles immunization targeting less than 15 years, and health
education on means of transmissions, treatment and prevention of measles infection should be
enhanced.
