Abstract
Background
Measles is an acute viral illness caused by a virus in the family paramyxo virus, genus Morbilli
virus. It is characterized by a prodrome of fever (as high as 105°F) and malaise, cough, coryza,
and conjunctivitis, followed by a maculopapular rash. Sidama zone Chire woreda reported
measles cases since 26 Dec 2015. And the investigation was conducted to identify the magnitude
of the outbreak and to undertake prevention and control interventions [1]. Laboratory
investigation was done for five cases and five cases were found to be positive for measles.
Methods
A case was defined as any person with fever and maculopapular rash and cough, coryza, or
conjunctivitis or any person in whom a clinician had suspected measles. And controls defined as
any person without sign and symptom of the disease. Structured questioner was used to collect
data from 40 cases and 80 controls. Patient observation was made at health centers and active
cases were searched house to house from 18 Jan 2016 to 19 Jan 2016. Five samples were
confirmed by laboratory investigation. Descriptive and case control analysis was conducted
using Epi-Info7 and Ms-Excel 2007.
Results
A total of 439 cases (Attack Rate: 1.00%) with 2 deaths case fatality rate (CFR: 0.5%) were
reported and the mean age of the cases is 7 years among all identified cases 229(52.2%) were
male. Compared to those who had no measles cases in the family, those who had measles cases
were more likely to develop measles adjusted odds ratio (AOR= 20.2; 95%CI: 6.69, 61.24).
Those cases with moderate malnutrition were more likely to develop measles compared to
normal nutritional status (AOR= 4.5; 95%CI: 1.08, 18.70) (Table 6).meaning those who have
measles cases in the family has 20times chance of developing measles than those who do not
have measles cases in the family on the other hand those who have moderate malnutrition have
4.5 times chance of developing measles
Conclusion
2
According to the analysis in this investigation shows that having sick person with measles in the
family and being moderately malnourished are associated with measles both sexes are almost
equally affected and age >15 are not affected by measles compared to the other age groups.
