Background: Municipal solid waste workers (MSWWs) are potentially exposed to diverse hazards that are not merely a consequence of their occupation. Of particular concern are infectious diseases. The endemicity of hepatitis B virus (HBV) infection in Egypt suggests the possibility of disease transmission in MSWWs from improperly disposed hazardous materials found in the solid waste stream. To date, such transmission has not adequately been epidemiologically studied in Egypt. Objective: To explore the seroprevalence of HBV among MSWWs in Egypt. Methods: We conducted a descriptive cross-sectional study that included 1467 MSWWs recruited from the main municipality company in Alexandria, Egypt, in February 2018. The enrolled participants were categorized into two occupational groups (exposed; n = 1361 and non-exposed; n = 115) on the basis of their direct exposure to solid waste. The study procedure involved interviews using a predesigned questionnaire that covered general demographic information. Blood samples from all participants were tested for the hepatitis B surface antigen (HBsAg), a marker of active HBV infection, using a third-generation enzyme linked immunosorbent assay (ELISA). Results: All MSWWs were male and had a mean age of 39.8 (±7.9) years. The majority were urban residents (72.8%) and engaged in solid waste collection (63.8%) or sorting (13.6%). The overall seroprevalence of active HBV infection was 1.5%. In total, 3.8% of the workers received the compulsory HBV vaccine during their infancy, meaning approximately 96.2% of the participants were at risk for HBV infection. Evaluating the availability and use of personal protective equipment revealed that most of the workers were provided with and wore overalls but not safety shoes, protective gloves, face masks, or helmets. Conclusion: The present work suggests the possible transmission of HBV in workers exposed to municipal solid waste. This result necessitates the initiation of prophylactic HBV immunizations and the consideration of safer techniques for waste management. |
