Background: According to the literature analysis, the majority of the studies focused primarily on public health institutions. Although assessing the compliance of healthcare workers in private and public institutions would give comprehensive evidence on existing problems and appropriate prevention method, as a result, research on adherence to standard precautions are still required. Rely on existing research, to the best of the investigator’s knowledge, compliance with standard precautions in hospitals of Bahir Dar town has not been assessed. Therefore, this study will contribute to narrowing these gaps and determining the scope of problems with standard precautions. Methods: An institution-based cross-sectional study design was conducted among 442 healthcare workers working in hospitals from June 10 to 30, 2021. A stratified random sampling technique was employed to select the study participants. Pre-tested and structured questionnaires and an observational checklist were used to collect the required data. The data were entered into EpiData and analyzed using SPSS version 22. Bivariate and multivariable analyses were used to assess the association between independent and outcome variables. Odd ratios at 95% CI were used to measure the strength of the association between the outcome and explanatory variables. Finally, a P-value of <.05 was considered as a cut-off point for statistical significance. Results: Of the 442 healthcare workers who participated in the study, 41% were compliant with standard precautions. Furthermore, 68.1% and 51.8% of the respondents had good knowledge and a positive attitude toward infection prevention, respectively. Consistent water supply availability (AOR = 1.92 and 95% CI = 1.63, 6.27), and access to infection prevention guidelines (AOR = 1.73 and 95% CI = 1.08, 2.77), and availability of personal protective equipment (AOR = 2.32 and 95% CI = 1.35, 3.98) were some of the factors significantly associated with health care workers’ compliance. Conclusions: The current study found that only about two-fifths of the healthcare workers complied with standard precautions. The study suggests that there is a significant risk of developing an infection. Therefore, the concerned organizations; Bahir Dar Zonal Health Office, and respective sectors including Amhara Regional Health Office and the Federal Ministry of Health must take appropriate measures to improve the implementation of safety practices.

Metals and metalloids pollution of Ethiopian surface water is becoming an environmental issue. Bioaccumulation and Biota-Sediment Accumulation Factor (BAF and BSAF) are used to quantify the bioaccumulation of contaminants from water and sediment to biota. The present study aimed to determine the BAF and BSAF of metals and metalloids in different surface waters of Ethiopia. Furthermore, the ecological and human health risks were also examined. Generally, 902 peer-reviewed papers from 2005 to 2022 were searched using search engines. The most common types of edible fish species in studied surface waters of Ethiopia were Oreochromis niloticus, Clarias gariepinus, and Barbus intermedius. The concentration of metals and metalloids were higher in sediment than in water and in carnivorous fish than in herbivorous fish. The BSAF of Se in all fish species was greater than 1. Oreochromis niloticus was a bio-concentrator of As and Se. The dissolved concentration of Cu, Cd, Pb, and Ni were higher compared to the Ethiopian Environmental Protection Authority and the European Union; Organization of Economic and Co-Operation Development environmental water quality standard guidelines for inland surface freshwater bodies. Likewise, in sediment, the concentration of Cu, Pb, Ni, Zn, and Cr were above Tolerable Effect Concentration values and Cd, Ni, and Cr were above Probable Effect Concentration levels when compared to the United States Consensus-Based Sediment Quality Guidelines for freshwater which indicates that these metals may pose risk to aquatic organisms. Consumption of raw water and fish contaminated with the detected metals and metalloids is not associated with any diseases. However, local consumers who live close to each freshwater ecosystem may become more exposed to health risk hazards. The findings of this study will provide baseline information on BAF and BSAF of metals and metalloids in surface waters and will contribute to the effective monitoring of environmental quality.
