Measles outbreak investigation in Tocha district, southwestern Ethiopia: an unmatched case-control study.

Background: Measles continues to be a public health challenge in Ethiopia. Rumors of suspected measles were notified on April 8, 2023 from Tocha district. We conducted an assessment to describe measles outbreak and determine risk factors for measles infection in the Tocha district of the Dawuro zone, Southwest Ethiopia. Methods: We conducted a 1:2 unmatched case-control studies from April to May 2023. We took all 147 cases registered on line list for descriptive analyses. We used a total of 74 randomly selected cases and 147 controls for case-control part. Any person in Tocha district with laboratory-confirmed measles IgM antibody; or any suspected person epidemiologically linked to confirmed measles cases from March 23 to April 26 2023, were included in the case. Neighborhood who did not fulfill this standard case definition were included in controls. Data were collected using standardized questionnaires deployed on Kobo Collect. Descriptive analyses were conducted using Epi info version 7.2.5.0. The analyses were performed using Statistical Package for Social Science (SPSS) version 26. Binary logistic regression analyses were utilized to select candidate variables. We conducted multiple logistic regression analysis to identify determinants of measles infection at a p value ≤0.05 with 95% confidence interval. Results: The overall attack rate of 22.64/10,000 for general population and 104.59/10,000 among under-five children were attributed to the outbreak with a case fatality rate of 2.72%. Vaccine coverage in the last year and this year were 73.52 and 53.88%, respectively, while vaccine effectiveness in the district was 79%. Poor house ventilation (AOR = 3.540, 95% CI: 1.663-7.535) and having contact history with the case (AOR = 2.528, 95% CI: 1.180-4.557) were positively related to measles infection while being previously vaccinated for measles (AOR = 0.209, 95% CI: 0.180-4.577) reduce risk of measles infections. Conclusion: The highest attack rate was observed among children under 5 years of age, with a case fatality rate of 2.72%. Vaccination coverage was less than what expected to develop herd immunity. Strategies to increase vaccination coverage and strengthening surveillance systems for rumor identification and early responses to prevent person to person transmission are recommended.

Mean difference in timing of first antenatal checks across regions and associated factors among pregnant women attending health facilities in Ethiopia: evidence from Ethiopian demographic health survey, 2019.

INTRODUCTION: Early initiation of antenatal care visits is an essential component of services to improve maternal health. Conducting a detailed study about the mean difference in timing at first antenatal checks across regions and factors associated with timing at first antenatal checks among women attending antenatal in Ethiopia is essential to ensure maternal and newborn health. Therefore, this study aimed to describe the mean difference in timing at first antenatal visits and associated factors among pregnant women attending different health facilities across regions in Ethiopia. METHOD: The Ethiopian Demographic and Health Survey (EDHS) conducted a community-based cross-sectional study in 2019. In this study, data about the timing of the first antenatal check-ups were requested from the Demographic Health Survey in February 2023, and the required variables were downloaded in SAS and SPSS formats from the data set. A total of 2935 women from nine regional states and two city administrations with an age range of 15 to 49 years were included in the study. The mean difference in timing at first antenatal check-ups, its correlation and various factors were estimated using multiple linear regressions to identify factors. RESULT: The majority of the 2034 (69.3%) of pregnant women who participated in the study were rural residents. The mean (± SD) age of the pregnant women was 29 (± 6.5) years. Approximately 32.5% of pregnant women visited their first antenatal check after 4 months of pregnancy. The results showed that counselling by health workers during a previous pregnancy (p < 0.01) significantly predicts timing at first antenatal checks in months holding previous delivery, previous antenatal care at both government and private facilities, ever attended school, and highest educational level. Timing at the first antenatal check-in months is expected to decrease by 0.99 months for every counselling session at each pregnancy. The results of the analysis suggested that the regression model significantly predicted timing at the first antenatal check (p = 0.001). CONCLUSION: The mean difference in timing at the first antenatal check in months among Ethiopian pregnant women relatively significantly varies in two regions. Previous pregnancy counselling by health workers positively influences the timing of first antenatal check-ups for subsequent antenatal check follow-ups in Ethiopia.
