Infection with the hepatitis B and C viruses may occur through parenteral contact associated with infected body fluids, including injury with infected sharps. Collectors of domestic or healthcare wastes are potentially exposed to these infections. The aim of this paper is to investigate the risk factors associated with the prevalence of hepatitis B and C (HBV and HCV) infection of domestic and healthcare waste workers in Belo Horizonte, Brazil. A cross-sectional study of hepatitis B and C infection was conducted from November 2014 to January 2015, through blood sample collection and interviews about socio-demographic factors with 61 workers exposed to healthcare waste ("exposed") and 461 exposed only to domestic wastes ("unexposed"). The prevalence of Anti-HCV antibodies was 3.3% in "exposed" workers and 0.9% in "unexposed", and of AntiHBc was 9.8% and 5.6% in "exposed" and "unexposed" workers, respectively. Only 207 (44.9%) of those exposed to domestic waste and 45 (73.8%) of those handling healthcare waste were higher among healthcare waste workers compared to domestic waste workers, probably because of needlestick accidents due to deficient sharps management systems. Immunization against hepatitis B and screening test to ensure the success of vaccination should be a condition for recruitment for both groups of waste workers.

“…The fl ow diagram and other details about the systematic search were published prevoiusly 13 . A total of 35 articles were selected for full-text screening; of these, 17 were excluded as the study populations did additional work besides waste collection (typically, they were healthcare staff such as physicians and nurses working at hospitals).…”

This meta-analysis, which is based on a previously published systematic review, aims to contribute to the scientifi c discussion on hepatitis B virus (HBV) infection in workers who are exposed to domestic and healthcare wastes. Publications were sought which had been made available on the data used by December 2013 and updated to December 2016. The quality of the included studies was assessed according to the guidelines of Loney et al. for the critical appraisal of studies on the prevalence or incidence of a health problem. To verify the presence of heterogeneity between the papers, we used the Chi-squared test based on a Q statistic. A funnel plot was used to test for publication bias. All included studies had across-sectional study design. The association between exposure to waste and positive serology for the HBV surface antigen (HBsAg) showed a signifi cant association [odds ratio (OR) 1.89, 95% confi dence interval (CI) 1.27-2.86; p = 0.0019]. The prevalence rates of HBsAg and anti-HBc seropositivity was 0.04 (95% CI 0.03-0.05) and 0.21 (95% CI 0.14-0.28), respectively (p <0.0001). We found no evidence of publication bias. The results of this meta-analysis indicate a statistically signifi cant association between exposure to solid waste, whether healthcare or domestic, and positive HBV infection markers. Therefore, the working conditions of waste collectors should be analyzed more closely. Immunization against HBV is recommended as the chief preventive measure for all solid waste workers.

Municipal solid waste could potentially transmit human pathogens during the collection, transport, handling, and disposal of waste. Workers and residents living in the vicinity of municipal solid waste collection or disposal sites are particularly susceptible, especially unprotected workers and waste pickers. Recent evidence suggests that municipal solid waste-mediated transmission can spread the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to humans. Such risks, however, have received little attention from public health authorities so far and may present an under-investigated transmission route for SARS-CoV-2 and other infectious agents during pandemics. In this review, we provide a retrospective analysis of the challenges, practices, and policies on municipal solid waste management during the current pandemic, and scrutinize the recent case reports on the municipal solid waste-mediated transmission of the coronavirus disease 2019 (COVID-19). We found abrupt changes in quantity and composition of municipal solid wastes during the COVID-19. We detail pathways of exposure to SARS-CoV-2 and other pathogens carried on municipal solid wastes. We disclose evidence of pathogenic transmission by municipal solid waste to humans and animals. Assessments of current policies, gaps, and voluntary actions taken on municipal solid waste handling and disposal in the current pandemic are presented. We propose risk mitigation strategies and research priorities to alleviate the risk for humans and vectors exposed to municipal solid wastes.
