Background: Between 2000 and 2018, global measles deaths decreased by 73%, but the disease remains prevalent in many developing countries, especially in Africa and Asia. Although Ethiopia was attempting to eliminate the measles, it still ranks fourth in the world in terms of the number of cases. The aim of the investigation was to describe the outbreak and identify its determinants in the Aneded district., Methods: Between March 3, 2020, and April 2, 2020, the 89 patients and 178 controls participated in a case-control study. Data were gathered by means of in-person interviews with household leaders. The attack and case fatality rates were determined. In multivariable logistic regression analysis, variables having a p-value of less than 0.05 were considered statistically significant cut-off points., Results: An investigation was conducted on a total of 89 measles cases, with 3 deaths and 178 controls. In total, there were 1.65 attacks per 1000 people, or 3.4% of the case fatality rate. There were 155 days of outbreak duration. The disease was significantly associated with being female [adjusted odds ratios (AOR) = 2.66; 95% confidence interval (CI) = 1.38-5.11], under 5 years old [AOR = 7.24; 95% CI = 2.58-20.31], positive in attitude [AOR = 0.22; 95% CI = 0.11-0.42], and having a contact history [AOR = 3.19; 95% CI = 1.67-6.10]., Conclusion: The measles outbreak, with its higher attack and case fatality rate, has been influenced by factors like household attitudes, age, sex, contact and travel history and needs to be reduced through early detection, active surveillance, and fostering favorable attitudes towards disease prevention and control., (© 2024.

Background: Pertussis, a highly contagious, vaccine-preventable respiratory infection caused by Bordetella pertussis, is a leading global public health issue. Ethiopia is currently conducting multiple pertussis outbreak investigations, but there is a lack of comprehensive information on attack rate, case fatality rate, and infection predictors. This study aimed to measure attack rates, case fatality rates, and factors associated with pertussis outbreak., Methods: This study conducted a systematic review and meta-analysis of published and unpublished studies on pertussis outbreaks in Ethiopia from 2009 to 2023, using observational study designs, using the guideline Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The study utilized databases like Science Direct, MEDLINE/PubMed, African Journals Online, Google Scholar and registers. The data were collected using an Excel Spreadsheet and then exported to STATA version 17 for analysis. Subgroup analysis was conducted to identify potential disparities. A random effects model was used to consider heterogeneity among studies. I 2 -squared test statistics were used to assess heterogeneity. The attack rate, case fatality rate, and odds ratio (OR) were presented using forest plots with a 95% confidence interval. Egger's and Begg's tests were used to evaluate the publication bias., Results: Seven pertussis outbreak investigations with a total of 2824 cases and 18 deaths were incorporated. The pooled attack and case fatality rates were 10.78 (95% CI: 8.1-13.5) per 1000 population and 0.8% (95% CI: 0.01-1.58%), respectively. The highest and lowest attack rates were in Oromia (5.57 per 1000 population and in the Amhara region (2.61 per 1000 population), respectively. Predictor of pertussis outbreak were being unvaccinated [odds ratio (OR) = 3.05, 95% CI: 1.83-4.27] and contact history [OR = 3.44, 95% CI: 1.69-5.19]., Conclusion: Higher and notable variations in attack and case fatality rates were reported. Being unvaccinated and having contact history were the predictors of contracting pertussis disease in Ethiopia. Enhancing routine vaccination and contact tracing efforts should be strengthened., (© 2024. The Author(s).)
