The aim of this study was to determine the prevalence of hepatitis B surface antigen (HBsAg) and associated risk factors among pregnant women attending antenatal clinics in Adigrat General Hospital in Northern Ethiopia. METHODS An institutional-based cross-sectional study was conducted from January to March, 2024, among 385 pregnant women. Participants were selected through a systematic random sampling method. Sociodemographic and associated factor data were collected using a structured questionnaire, and 5 mL blood samples were collected. The data were subsequently entered into EPI Info and analyzed using SPSS version 25. Descriptive statistics were computed. Bivariate and multivariate regression analyses were employed to measure associations, and values < 0.05 were considered to indicate statistical signi cance. RESULTS The overall seroprevalence of HBsAg among the 385 study subjects enrolled was 10.4% (n = 40). HBsAg was common in all age groups. The prevalence of infection was greater in those who had a history of multiple sexual partners (22.7%), early piercing (13.4%), or abortion (27.6%), as was the history of delivery (26.3%) and genital mutilation (35.7%). According to multivariate logistic regression, patients

Salmonella and Shigella are the most common foodborne pathogens and their infections are a major public health problem globally. Thus, this study aimed to determine the prevalence, antimicrobial susceptibility patterns, and associated factors of Salmonella and Shigella among food handlers. Methodology: A cross-sectional study was conducted from March to August 2018 at Adigrat University student cafeteria, Northern Ethiopia. Data on socio-demographic and associated factors were collected using a structured questionnaire. Fresh stool samples were collected from 301 food handlers and transported to Adigrat University Microbiology Laboratory. Bacterial isolation and antimicrobial susceptibility test were performed using standard bacteriological methods. Data analysis was performed using SPSS version 22 and P < 0.05 with a corresponding 95% con dence interval was considered statistically signi cant. Results: A total of 301 food handlers were included in this study. The majority of study participants were females 265 (88.0 %). About 22 (7.3%) and 11 (3.7%) of food handlers were found to be positive for Salmonella and Shigella respectively. Hand washing after using a bathroom with water only,no hand washing after using the bathroom,no hand washing after touching dirty materials, no hand washing before food handling, and untrimmed ngernails were signi cant associated factors identi ed. None of the Salmonella and Shigella isolates were sensitive to ampicillin. On the other hand, low resistance against chloramphenicol, ceftriaxone, and cipro oxacin was found. Conclusion: The present study revealed that the prevalence of Salmonella and Shigella among food handlers was 22 (7.3%) and 11 (3.7%) respectively. Such colonized food handlers can contaminate food, drinks and could serve as a source of infection to consumers via the food chain. This indicates that there is a need for strengthened infection control measures to prevent Salmonella and Shigella transmission in the students' cafeteria.

In Ethiopia, despite the high prevalence, morbidity, and socioeconomic impacts, little information is available about the disease. Thus, this review aimed to assess the effect of sex differences and pooled prevalence of podoconiosis in Ethiopia. Study setting: Ethiopia is a country located in East Africa. Methods: Published literature on the prevalence of podoconiosis in Ethiopia was searched through MEDLINE/ PubMed, Cochrane Library, Goggle scholar, and Global Health. Studies conducted in humans, open access, and met 50% threshold on the quality assessment checklist score adopted from Joanna Briggs Institute were eligible for inclusion. Data were extracted using first author, year of publication, participants' population, setting (urban/ rural), study design, podoconiosis infection among males, the total number of males, podoconiosis infection among females, the total number of females, and context using Microsoft™ Excel. R statistical software version 3.6.1 was utilized to carry out the meta-analysis. The protocol of this review is registered in the PROSPERO international prospective register of systematic reviews and assigned a registration number of CRD 42020154697. Results: We performed heterogeneity, sensitivity, and publication bias analysis for the included articles. We identified 229 records, of which 11 studies met the inclusion criteria. The pooled prevalence of podoconiosis in Ethiopia was 6% [95% CI: 5%; 6%]. Subgroup analysis by setting indicated slightly higher prevalence in rural settings. The odds of podoconiosis infection among female is 1.15 times that of males" The effect of sex on podoconiosis was sub-grouped by study setting and the odds of females were 1.29 times at increased risk of acquiring podoconiosis than males (p < 0.01) in rural settings. Conclusions: The prevalence of podoconiosis in Ethiopia is high. This review suggested that females are at higher risk of developing podoconiosis than males, particularly in rural communities which has health promotion and awareness implications regarding protective wear.

Managing and detecting antiretroviral treatment response is important to monitor the effectiveness of medication and possible drug switching for low immune reconstitution. There is less recovery of CD4+ T cells among human immunodeficiency virus patients infected with tuberculosis. Hence, we aimed to assess the effect of tuberculosis and other determinant factors of immunological response among human immunodeficiency virus patients on highly active antiretroviral therapy. A retrospective follow up study was conducted from October to July 2019. A total of 393 participants were enrolled. An interviewer based questionnaire was used for data collection. Patient charts were used to extract clinical data and follow up results of the CD4+ T cell. Current CD4+ T cell counts of patients were performed. STATA 13 software was used to analyze the data. Ap-value ≤0.05 was considered a statistically significant association.Results...

The two hepatotropic viruses share common modes of transmission and their co-infection is common. Despite the provision of an effective prevention mechanism, the infections caused by these viruses remain a significant problem worldwide, particularly among developing countries like Ethiopia. Methods This institutional-based retrospective study was conducted between January 2014 December and December 2019 from documented laboratory logbooks of Adigrat general hospital serology laboratory, Tigrai, Ethiopia. data were collected and checked for completeness on a daily based, coded, entered, and cleaned using Epinfo version 7.1, exported and analyzed using SPSS version 23. Binary logistic regression analysis and Chi-square test (X 2) assessed the association between dependent and independent variables. The corresponding variables with a P-value (P < 0.05) and 95% confidence interval were considered statistically significant. Results Out of 20,935 clinically suspected individuals, 20,622 were given specimens and tested for hepatitis B and C viruses with total completeness of 98.5%. The overall prevalence of hepatitis B and hepatitis C virus was found to be 3.57% (689/19,273) and 2.13% (30/1,405), respectively. The positivity rate of the hepatitis B virus was 8.0% (106/1317) and 3.24% (583/17,956) among males and females, respectively. Additionally, 2.49%(12/481) of males and 1.94% (18/924) of females were positive for hepatitis C virus infection. The overall prevalence of co-infection for both hepatitis B and hepatitis C virus was 7.4% (4/54). Sex and age were significantly associated with hepatitis B and C virus infection. Conclusions The overall prevalence of hepatitis B and C is low intermediate according to the WHO criteria. Although there was a fluctuating trend of hepatitis B and C through the years 2014-2019, the result shows moreover declining trend. Both hepatitis B and C share similar routes of transmission and affect all age categories but males were more highly affected than females. Therefore, awareness creation of the community about the methods of transmission, education about prevention, and control of hepatitis B and C virus infection, and improving coverage of youthfriendly services in health facilities should be strengthened.

However, much of the world’s population lacks access to adequate and safe water. Approximately 884,000, 000 people in the world still do not get their drinking water from safe sources; Sub-Saharan Africa accounts for over one third of this number. It is estimated that 80% of all illnesses in the world are related to use of unsafe and contaminated water. Methods A cross-sectional study was conducted from August 1st 2017 to July 30th 2018 in three randomly selected woreda (districts) of Eastern Zone Tigrai. Water samples were examined for total coliforms and thermotelorant coliforms using the most probable number method. Standard biochemical testing was performed on samples that tested positive to identify the genus of bacteria. The contaminant risk of water sources were assessed using the sanitary inspection checklist of the World Health Organization. The results were interpreted usin...
