Measles outbreak investigation in Artuma Fursi Woreda, Oromia Zone, Amhara Region, Ethiopia, 2018: a case control study

OBJECTIVE: To confirm the existence of Outbreak, describe cases in person, place and time, and identify determinants of the outbreak. Unmatched case control study in the ratio of 1:4 (38 cases and 152 controls) was conducted in Artuma Fursi Woreda from July 13 to August 1/2018. Data were collected with standard questionnaires. Collected data were entered into Epi Info version 7 and exported to Statistical package for social science (SPSS) version 23 for analysis. RESULTS: A total of 38 cases and 1 death with attack rate and case fatality rate 11.8/100,000 and 2.6%, respectively. All study participants had not vaccination history. Females and age group 5–14 were more affected. Being 5–14 years old versus (vs) ≥ 15 years [adjusted odd ratio (AOR) = 3.53; 95% CI 1.52–8.45)], contact with cases vs no contact with cases [AOR = 2.78; 95% CI 1.23–8.67] and travel history 7–18 days prior onset of illness vs no travel history [AOR = 2.53; 95% CI 1.31–7.24] were significantly associated with contracting measles. Routine and supplement immunization should be strengthened to reduce future occurrence of outbreak.
