Objectives Anemia remains a major public health problem in Ethiopia, which causes maternal and fetal severe consequences. In Tigrai, there are limited literatures on prevalence of anemia and associated factors among pregnant women. Thus, a hospital based cross-sectional study was conducted to determine the prevalence and associated factors of anemia in Adigrat General Hospital. Data was analyzed and computed using SPSS version 22. p value = 0.05 at 95% confidence interval was considered statistically significant. Results Overall prevalence of Anemia among the pregnant women attending Adigrat General Hospital was 7.9%. About 62.5% and 37.5% of the anemic women were with mild (Hgb: 10.0–10.9 g/d1) and moderate (Hgb: 7–9.9 g/dl) type respectively. Factors like, residing in rural areas increases risk of anemia by 6 times (AOR = 6, 95% CI 1.34, 27.6, p = 0.019), participants having current blood loss (AOR = 3.4, 95% CI 1.16, 10.2, p = 0.026), having history of recent abortion (AOR = 7.9, 95% CI 2.23, 28.1, p = 0.001) and gestational age in the third trimester (AOR = 4.9, 95% CI 1.39, 17.6, p = 0.013) were statistically associated with anemia. Generally, prevalence of anemia is found to be low in the study area. However, it should be given due attention. Therefore, strong endeavor is needed to control anemia among pregnant women by assessing different micronutrient deficiencies for further prevention.

Background: In Ethiopia, despite the integrated implementation of antiretroviral therapy since 2005, the human immunodeficiency virus remains a public health concern. Managing and detecting antiretroviral treatment response is important to monitor the effectiveness of the therapy for individuals who experience failed virological response. An increased viral load indicating drug resistance or rapid progression of viral replication needs early detection. Hence, we aimed to assess the prevalence and determinants of virological response among human immunodeficiency virus-infected patients on highly active antiretroviral therapy. Methods: A hospital-based cross-sectional study was conducted in Adigrat General Hospital from September to December, 2019, on a total of 422 participants. An interviewerbased questionnaire was used for data collection. About 4 mL of venous blood was collected for viral load determination. Patient records were reviewed for the previous results of CD4+ T cell counts. STATA 14 software was used to analyze the data. Descriptive data were presented using tables and figures. Bivariate and multivariate analyses were performed. A p-value < 0.05 was considered a statistically significant association. Results: The mean age of study participants was 39 years (SD ±12.2 years), of which 66.7% of them were females. The overall prevalence of virological failure was 12.47% (49/393). Moreover, the prevalence of virological failure was observed to be higher among tuberculosis co-infected individuals (26%) compared with the mono-infected HIV patients (6.3%). The odds of virological failure were higher among obese and undernourished individuals, tuberculosis co-infected, and individuals with the failure of immune reconstitution. Conclusion: There was a high rate of virological failure among the study participants. Tuberculosis infection increased the rate of failure. There should be consistent assessment of viral load testing to determine the status of virological response for appropriate drug switching to clients. HIV patients with virological failure are recommended for switching of the antiretroviral therapy.

Background: Access to safe drinking water is one of the basic human rights and is critical to health. 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 using World Health Organization guidelines for drinking water quality. Data was collected using laboratory checklist and sanitary inspection check list. It was entered, cleared and analyzed using SPSS version 21.0 and a variable having a P < 0.05 was considered as statistically significant in all tests. Results: A total of 290 drinking water samples were analyzed for bacteriological quality. A total of 32.4% (n = 94) of water sources showed contamination with faecal and total coliforms. Of these 3.4% (n = 10) samples were contaminated with total coliforms and 29% (n = 84) contaminated with faecal coliforms. The leading water contaminant organisms were Escherichia coli (62.4%), Legionella species (8.5%), and Shigella species (7.5%) respectively. Based on WHO criteria, 15% of water sources were grouped in the very high risk group. Animal excreta and inadequate fencing of water sources were significantly associated with water contamination rate. Conclusion: Our findings suggest that most water sources in woredas of Eastern Tigrai are contaminated by faecal coliforms. Therefore, regular sanitary inspection, bacteriological analysis, and adequate fencing should be mandatory to protect drinking water sources from faecal contamination.

Background Globally, the novel coronavirus is a public health problem causing respiratory infections. Since the outbreak of severe acute and Middle East respiratory syndromes coronavirus was not reported to cause human infections. Now, it becomes an epidemic proportion with growing number of cases and deaths.Methods A scoping review was conducted following the methodological framework. In this scoping review, 50 records published before 28 March, 2020 were included and discussed to better understand the current epidemiology, pathogenesis, immunological response, diagnosis, evasion mechanisms and suggested strategies to boost immune system, challenges, treatment, and future preventions of the virus. PubMed, BioRxiv, MedRxiv, Global Health and google scholars were searched comprehensively for articles, preprints, grey literatures, reports, websites, conference proceedings and expert information. Studies conducted in human and published in English language were included in the analysis. All the findings and statements of the review regarding the outbreak are based on published information as listed in citations.Results We identified 360 records, of which 50 studies met the inclusion criteria. We synthesized the data from the included records and dig out the deep insights of them and pooled in to this review. The burden of the outbreak is worsening due to overcrowding, presence of asymptomatic carriers, scarcity of test kits, immune escaping ability of the virus and lack of awareness.Conclusions and recommendations: Due to the fast spreading nature of COVID-19 the prevention and control strategies become challenging. It is imposing social, psychological, and socio-economic impacts. We recommended that following social distancing, isolation suspects, using personal protective equipment, health education and introducing hand washing practices, avoiding contact with animals, vaccine development and treatment for controlling and prevention.

Background Isoniazid prophylaxis therapy is a significant public health intervention to prevent the progression of latent tuberculosis to active tuberculosis disease among people living with HIV. Those with HIV are at high risk to develop active Tuberculosis from latent Tuberculosis than those without HIV. Even though there is strong evidence supporting Isoniazid Prophylaxis therapy for Tuberculosis prevention, there is limited information about the implementation of isoniazid prophylaxis therapy in Ethiopia as well as in the study area. Objective To determine the effects of Isoniazid Prophylaxis therapy and its associated factors among HIV positive clients taking antiretroviral therapy at Fre Semaetat primary Hospital, Hawzien districts, Tigray, northern Ethiopia. Method Institutional based cross-sectional study design was conducted from April to August 2019 among HIV positive clients who came to Fre Semaetat primary Hospital. Data related to socio-demographic characteristics and associated risk factors were taken from 372 HIV positive clients who were selected by a simple random sampling method. Data was coded and cleaned by using SPSS version 23.0 for the final analysis. Results A total of 372 HIV positive clients taking antiretroviral therapy were included in the study. Of those, the overall prevalence that took and completed their Isoniazid Prophylaxis therapy for 6 months was found to be 231(62.1%). From those who completed Isoniazid Prophylaxis therapy (IPT), 13(3.5%) was developed active Tuberculosis (TB) incidence. Gender, co-trimexazol Prophylaxis therapy users, HIV positive clients who took Anti-pain and married clients were the predictor among statistically significant variables of Isoniazid Prophylaxis therapy. Conclusions Isoniazid Prophylaxis therapy utilization found to below. Therefore, health education and counseling of patients who are in their first 2 months of therapy should be strengthened further. Prophylaxis should be given by service providers, medication side effects should be addressed rapidly.

BackgroundEthiopia initiated antiretroviral therapy early in 2005. 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. A p-value ≤0.05 was considered a statistically significant association.ResultsThe mean age of study participants was 39.2 years (SD: + 12.2 years) with 8.32 mean years of follow up. The overall prevalence of immune reconstitution failure was 24.7% (97/393). Highest failure rate occurred within the first year of follow up time, 15.7 per 100 Person-year. Failure of CD4+ T cells reconstitution was higher among tuberculosis coinfected patients (48.8%) than mono-infected patients (13.7%). Living in an urban residence, baseline CD4+ T cell count ≤250 cells/mm3, poor treatment adherence and tuberculosis infection were significantly associated with the immunological failure.ConclusionsThere was a high rate of CD4+ T cells reconstitution failure among our study participants. Tuberculosis infection increased the rate of failure. Factors like low CD4+ T cell baseline count, poor adherence and urban residence were associated with the immunological failure. There should be strict monitoring of CD4+ T cell counts among individuals with tuberculosis coinfection.

Background Food handlers play a significant role in the transmission of foodborne infections. 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 colonization 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 where a corresponding 95% confidence interval was considered statistically significant. 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 fingernails were significant associated factors identified. None of the Salmonella and Shigella isolates were sensitive to ampicillin, yet low resistance against chloramphenicol, ceftriaxone, and ciprofloxacin 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, and drinks and could serve as a source of infection to consumers. This indicates that there is a need for strengthened infection control measures to prevent Salmonella and Shigella transmission in the students’ cafeteria.
