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with pertussis outbreak., Methods: This study conducted a systematic review and meta-analysis of published and unpublished studies on pertussis outbreaks in Ethiopia from 2009 to 2023, using observational study designs, using the guideline Preferred Reporting Items for Systematic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).)

Background: The magnitude of on-time appointment keeping among HIV-positive adult patients was not identified in Ethiopia. Hence, this study aimed to assess on-time appointment keeping and associated factors among human immunodeficiency virus-positive patients accessing antiretroviral therapy in the East Gojjam Zone, Northwest Ethiopia., Methods: A community-based cross-sectional study was performed on 830 HIV-positive patients from April 1 to May 10, 2019, in East Gojjam Zone. A systematic random sampling technique was used to include study subjects, and data were collected through face-to-face interviews. Bivariable and multivariable binary logistic regression analyses were performed. Independent variables with a P value of <0.05 were considered statistically significant cut points., Results: The prevalence of on-time appointment keeping was 62.1%. Being >24 years old (adjusted odds ratio (AOR) = 2.13; 95% confidence interval (CI) = 1.54-4.25), being unmarried (AOR = 0.59; 95% CI = 0.45-0.82), taking a drug regimen of tenofovir + lamivudine (3TC) + efavirenz (EFV) (AOR = 2.11; 95% CI = 1.84-3.62), taking ART ≥12 months (AOR = 4.32; 95% CI = 2.22-8.40), having a mobile (AOR = 2.22; 95% CI = 1.44-3.64), and getting adherence support (AOR = 1.83; 95% CI = 1.16; 95% 1.16-3.50) were significant factors., Conclusion: On-time appointment keeping was low. Adherence support and appointment reminders should be strengthened., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2023 Mengistie Kassahun Tariku et al.)

Background: Although Ethiopia is working towards measles elimination, a recurrent measles outbreak has occurred. To take appropriate measures, previously, many fragmented and inconsistent outbreak investigations were done, but there is no consolidated evidence on attack rate, case fatality rate, and determinants of measles infection during the measles outbreak. This systematic review and meta-analysis aimed to identify cumulative evidence on attack rate, case fatality rate, and determinants of measles infection during the outbreak., Methods: A systematic literature review and Meta-analysis was used. We searched Google Scholar, Medline/PubMed, Cochrane/Wiley Library, EMBASE, Science Direct, and African Journals Online databases using different terms. Investigations that applied any study design, data collection- and analysis methods related to the measles outbreak investigation were included. Data were extracted in an Excel spreadsheet and imported into STATA version 17 software for meta-analysis. The I 2 statistics were used to test heterogeneity, and 'Begg's and 'Egger's tests were used to assess publication bias. The odds ratio (OR) with a 95% confidence interval (CI) was presented using forest plots., Results: Eight measles outbreak investigations with 3004 measles cases and 33 deaths were included in this study. The pooled attack rate (A.R.) and case fatality rate were 34.51/10,000 [95% CI; 21.33-47.70/10,000] population and 2.21% [95% CI; 0.07-2.08%], respectively. Subgroup analysis revealed the highest attack rate of outbreaks in the Oromia region (63.05 per 10,000 population) and the lowest in the Amhara region (17.77 per 10,000 population). Associated factors with the measles outbreak were being unvaccinated (OR = 5.96; 95% CI: 3.28-10.82) and contact history (OR = 3.90; 95% CI: 2.47-6.15)., Conclusion: Our analysis revealed compelling evidence within the outbreak descriptions, highlighting elevated attack and case fatality rates. Measles infection was notably linked to being unvaccinated and having a contact history. Strengthening routine vaccination practices and enhancing contact tracing measures are vital strategies moving forward., (© 2023. The Author(s).)

Background: Hookworm infection is a major public health problem in developing countries. The main way people become infected with hookworm's larva is through direct skin contact with contaminated soil when walking on barefoot. It is one of a major cause of anemia in pregnant women. The objective was to assess the prevalence and associated factors of hookworm infection among pregnant women who attended antenatal care at governmental health centers in Dembecha district, Ethiopia, 2017., Methods: Institutional based cross sectional study was conducted on 306 pregnant women. Study participants were selected by systematic random sampling technique from February 1 to March 30, 2017. Data collectors and supervisors were trained. Semi-structured Amharic version questionnaire was used to collect data using face to face interview technique and stool sample was examined. Collected data were entered by using Epi data version 3.1 and exported to SPSS. The exported data was analyzed and presented by using descriptive summary statistics and tables. After bivariate logistic regression analysis, all variables with a p-value < 0.25 were entered into multivariate logistic regression and p value < 0.05 considered as significantly associated with the outcome variable., Results: Prevalence of hookworm infection was 32.0%. There was a positive association of hookworm infection with living in single room [AOR =2.8; 95% CI; 1.32-5.81], living with domestic animals [AOR = 3.4; 95% CI; 1.35-8.76], monthly income ≤1500 Ethiopian birr [AOR = 3.7; 95% CI; 1.76-7.64], unavailability of latrine [AOR = 2.2; 95% CI; 1.03-4.55], habit of walking on barefoot [AOR = 4.3; 95% CI; 2.17-8.48] and not habit of hand washing before meal [AOR = 3.4; 95 CI; 1.14-10.12]., Conclusion: This study showed high prevalence of hookworm infection among pregnant women in the study area. Living in single room, living with domestic animals, monthly income ≤1500 Ethiopian birr, unavailability of latrine, habit of walking on barefoot and not habit of hand washing before meal had positive association with hookworm infection. Public health measure should focus on availability latrine and separation of humans and domestic animals room to decrease prevalence of hookworm infection among pregnant women.

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.
