Background Measles is a highly contagious viral illness and globally, 142,300 people died from measles in 2018. On 25 March 2021, an outbreak of measles was reported from Guradamole district Bale Zone Southeast Ethiopia. Hence, we investigated to determine existence of the outbreak and to identify the associated factors. Method Descriptive and 1:2 unmatched case–control study was done in Guradamole district from March 25 to April 9/2021. For the descriptive study, a total of 98 cases were used. To identify the factor associated with the outbreak, 60 cases were selected by computer-generated simple random method by using line list as a sampling frame and 120 controls were studied. Active cases were identified through home-to-home searching in affected kebeles and controls were selected from neighbors of cases. Five serum samples were taken and an IgM test was done to confirm cases. Cases were any person who developed fever, maculopapular rash and cough, coryza or conjunctivitis while controls were without such diagnosis. We collected data by using a structured questionnaire, cases were described by time, place, and person; logistic regression was used to identify factors associated with measles. In the multivariable analysis P -value <0.05 was declared statistical significance. Results Overall, 98 cases were identified with an overall attack rate of 12/1000 population and a case fatality rate (CFR) of 7%. The highest attack rate (38/1000 population) and CFR (57%) were among children aged <59 months. Vaccination efficacy was calculated to be 82.6%. Being unvaccinated (adjusted odds ratio/AOR=5.66, 95% confidence interval, CI: 1.24–25.81), contact with patient (AOR=3.24, 95%CI: 1.03–10.17), moderate malnutrition (AOR=4.34, 95%CI: 2.14–8.814), distance from health facility (AOR=4.58, 95%CI: 1.39–15.19) and history of travel to affected area (AOR=3.99, 95%CI: 1.31–12.19) were shown significant associated with measles infection. Conclusion The attack and fatality rate of the investigation were high. Being unvaccinated, distant from the health facility, malnutrition, and history of contact with measles case were associated with the outbreak. We recommend conducting vaccination campaigns, interventions to malnutrition, and strengthening routine immunization programs to reduce future measles outbreaks.

Background Measles remains a cause of vaccine-preventable death in children worldwide. Reported cases in Ethiopiarepresent only a small proportion of expected cases, due to weak measles-based surveillance implementation. In this study, we aimed to analyze 7 years’ measles-surveillance data from Bale zone, in order to indicate measles epidemiology and surveillance-related gaps. Methods This cross-sectional study was conducted from May to June 2019. The study population was all measles cases reported to the Bale Zone Health Office from 2013 to 2019. Data were abstracted from 7 years’ measles line lists and case-based reports using a data-abstraction check-list. Data were analyzed using Microsoft Excel and Pivot software, and were presented in tables and graphs. Results Overall, 4,241 measles cases were reported from 2013 to 2019. Mean age was 7.15 years, and 50.6% were male. The most affected age-group was children <4 years of age. Analysis indicated that the case-fatality rate was 3.07/1,000 population. Of the total cases reported, 248 (5.8%) were IgM-confirmed. The highest prevalence of 141/100,000 population was reported in 2019. Unvaccinated cases and those with unknown vaccination status numbered 890 (21%) and 731 (17.2%), respectively. The highest number of cases was reported from Ginir and Gololcha districts. Cases increased in autumn each year and peaked in May. Conclusion Measles is a major cause of morbidity and mortality in Bale, due to poor immunization coverage. Its case fatality is also high, excluding community deaths. Of all the districts included, Ginir reported the highest number of cases. Improving vaccination coverage, early preparedness for the annual epidemic cycle, and strengthening case-based surveillance are important interventions to reduce measles morbidity and mortality.

Background: - Measles remains causes of vaccine preventable death in children worldwide. Cases comes to health facilities after complication developed, and miss diagnosed as the complication than measles, which is a reason for under reporting of measles cases and number of reported cases represents small proportion of expected cases. While aim of this study is to analyze seven years (2013-2019) measles surveillance data of Bale zone and to indicate measles surveillance related gaps. Method: - Cross sectional study conducted from May 25-June 25/2019. Study population and sample was all measles cases reported to bale zone from 2013-2019. Data abstracted by reviewing seven years measles line list and case-based report by investigator using data abstraction check list. Data entered and analyzed by Microsoft excel. Tables, graph and percent presented the data. Result: - Overall, 4241 measles cases were reported with a case fatality of 3.07/1000 population. About 248(5.8%) were measles IgM confirmed. Mean age of the case patients were 7.15 and 2147 (50.6%) were males. The most affected age group were <4 years, 1685 (39.7%) of cases. The highest prevalence rate 141 / 100,000 populations reported in 2019.Unvaccinated and unknown status were 890(21%) and 731(17.2%). The highest numbers of cases reported from Ginir and Gololcha. Measles cases increase in autumn season of the year and reaches peak in May. Conclusion: - Measles is the major causes of morbidity and Mortality in Bale zone due to poor immunization coverage, 890(21%) of case patients were un vaccinated. Though community death is not included case fatality is high. Ginir reported the highest number of cases. Increasing vaccine coverage of the zone, early preparedness before annual cycle and strengthening measles case-based surveillance is mandatory.
