Abstract
Background: Measles is a highly infectious viral disease that can cause permanent disabilities
and death. We investigated measles outbreak to identify the magnitude and factors associated
with measles in Cheta woreda, Kefa Zone, SNNPR 2016.
Methods: We investigated 50 cases and 100 controls. We used a descriptive study followed by
un-matched 1:2 cases to controls were conducted from February to March 2016. We defined a
suspected measles case as any person with fever, rash, cough, and coryza or a person suspected
of measles by a clinician. Four blood specimens were collected for laboratory confirmation. Data
collection instrument was prepared. Multivariate logistic regression analysis was conducted by
using Epinfo 7.
Result: A total of 136 cases with AR 10.6/1000 and five deaths (CFR 3.6%) were identified.
The median age of the cases was 3 years and IQR age was between 2 and 5years. Thirty-five of
the cases (70%) and thirty-four (34%) of the controls were not vaccinated. Twenty-nine (58%)
cases and 45 (45%) controls were males. The risk factors for contracting measles are - history of
contact with suspected or confirmed cases (AOR=18.00 CI 4.31-80.46). Family size peoples
living in one house more than five (AOR= 4.00 CI 1.34-11.98), Being vaccinated was protective
effect from acquiring measles (AOR= 0.30 CI 0.10-0.78), Knowledge about measles disease is
vaccine preventable (AOR= 0.27 CI 0.10-0.73).
Conclusion: The most affected age group under five (54%) years followed by 5-14 (32%) years
of age. History of contact with suspected or confirmed cases, Un-vaccination, living people more
than five members and Lack of knowledge of mother or caretaker were associated risk factors.
We recommended supplementary measles vaccination for under 15 children, strengthening of
routine immunization defaulter tracing, strengthening of cold chain management and awareness
creation in the community.
