“…The pooled prevalence of HBV infection among waste handlers was 5.07%, with great heterogeneity between its regional states in Ethiopia. The finding of this meta-analysis was lower than the previous findings reported from studies conducted in Nigeria, 36 Brazil, 37 Pakistan, 38 and Central Greece, 39 which showed HBV prevalence rates in waste handlers of 14%, 17.4%, 18.8%, and 23.0%, respectively. The lower prevalence rate of HBV in this study might be explained by differences in the behavioral characteristics of waste handlers recruited in the primary studies.…”

Objective: Hepatitis B virus and hepatitis C virus are the leading causes of global liver-related morbidity and mortality. Waste handlers are one of the high-risk groups for hepatitis B virus and hepatitis C virus acquisition. Thus, the aim of this study was to assess the pooled prevalence of hepatitis B virus and hepatitis C virus among waste handlers in Ethiopia. Methods: Articles were extensively searched in bibliographic databases and gray literature using entry terms or phrases. Studies meeting eligibility criteria were extracted in MS Excel and exported to STATA version 14 software for statistical analysis. A random-effects model was used to compute the pooled magnitude of hepatitis B virus and hepatitis C virus. Heterogeneity was quantified by using the I2 value. Publication bias was assessed using a funnel plot and Egger’s test. Sensitivity analysis was performed to assess the impact of a single study on pooled effect size. Result: Of the 116 studies identified, 8 studies were selected for meta-analysis. All studies reported hepatitis B virus, while 5 studies reported hepatitis C virus infection among waste handlers. The overall pooled prevalence of hepatitis B virus and hepatitis C virus infection among waste handlers in Ethiopia was 5.07% (2.0–8.15) and 1.46% (0.52–2.4), respectively. Moreover, the pooled prevalence of lifetime hepatitis B virus exposure among Ethiopian waste handlers was 33.98% (95% CI: 21.24–46.72). Hepatitis B virus and hepatitis C virus infection were not statistically associated with the type of waste handlers, that is, there was no difference between medical and nonmedical waste handlers. PROSPERO registration: CRD42023398686. Conclusion: The pooled prevalence of hepatitis B virus and hepatitis C virus infection among waste handlers in Ethiopia was intermediate and moderate, respectively. This showed that there is a strong need to scale up preventive efforts and strategic policy directions to limit the spread of these viruses. Moreover, we also conclude that handling healthcare and domestic waste is associated with a similar risk of hepatitis B virus and hepatitis C virus infection.

Background Healthcare workers (HCWs) are at higher risk of contracting hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. Currently, there is no estimate of pooled data on the prevalence of HBV and HCV infections among HCWs in the country. Thus, this review aimed to determine the pooled prevalence of hepatitis B and C infections among HCWs in Ethiopia. Materials and methods A comprehensive literature search was conducted using electronic databases, including PubMed, Cochrane Library, Science Direct, Hinari, and African Journals Online to identify pertinent articles from the inception to April 2024. The protocol has been registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42024527940) and conducted per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data were extracted independently by two authors and analyzed using STATA version 11 software. A random-effect model and Egger’s test were computed to estimate the pooled prevalence and assess publication bias, respectively. Results A total of 18 studies involving4,948 healthcare workers were included in this review to estimate the pooled prevalence of HBV and HCV infections among HCWs in Ethiopia. The overall prevalence of HBV was 5.93% (95% CI; 3.22–8.63). The sub-group analysis showed that the prevalence of HBV among medical waste handlers and health professionals was8.6% (95% CI; 3.01–14.13) and 4.98% (95% CI; 1.85–8.11), respectively. The combined prevalence of HCV was 1.12% (95% CI; -4.19–6.43). In the sub-group analysis, the prevalence of HCV among medical waste handlers and health professionals was1.44% (95% CI; -5.28–8.18) and 0.59% (95% CI; -8.09–9.27), respectively. Conclusion In this review, we found a higher (5.93%) and moderate (1.12%) prevalence of HBV and HCV infections, respectively among Ethiopian HCWs. Therefore, to reduce the infectious burden of HBV and HCV among HCWs; there is a need to strict adherence to infection prevention and control measures. In addition, adequate HBV vaccination coverage for HCWs is mandatory to reduce the burden of HBV infection in the country.
