Abstract
Introduction: Measles outbreak is still a public health problem in different Ethiopian regions.
Hulla district reported a measles out-break in February, 2015 to South Region Nation and
Nationality health office , despite vaccination coverage of the district 99% in 2013,105% in
2014 and 96% six month coverage of 2015. Therefore, I conducted the investigation to assess the
magnitude and determine contributing factors for the occurrence of measles outbreak.
Method: Descriptive epidemiologic study and A 1:1 unmatched case control with total of 50
cases and 50 control study was conducted. For the descriptive, a total of 307 cases were
participated based on the measles line listing records. . Discussed, interviewed and reviewed
with key informants about the cold chain management, EPI coverage, reporting system and EPI
data quality of the Hulla district.
Results: Majority of the cases, 184 (60%), were between 5-14years of children. The attack rate
became 452 per 100,000 populations with zero case fatality rate. The vaccination statuses from
the whole cases were, 44 (14%) were unknown case, 14(5%) were two dose, 53(17%) one dose
and 196(64%) zero dose. Contact history with sick and travel history two weeks prior to the
onset of symptoms were significantly associated with Odds ratio of 126(15.8, 1002), and 16(3.5,
73) respectively.
Conclusion: In order to reach the age group of 5-14 years, providing a second opportunity for
measles vaccination through supplementary immunization seems important. Additionally, early
notification and response, improving routine vaccination, strength surveillance system in all
levels could be an ideal approach to reduce measles outbreak and its complication.
