“…Compared with the prevalence in other Brazilian populations, the prevalence determined in this study was within the confi dence interval range recorded for patients attending an STD clinic (13%; 95% CI: 10.0-16.5) 20 , non-injection drug users (14%; 95% CI: 11.7-16.5) 21 and individuals reporting to an HIV testing and counseling center (14.6%; 95% CI: 11.2-18.0) 22 . Nevertheless, relative to other reported data on recyclable waste collectors, the prevalence found in the present study was lower than that observed in Santos, Brazil (34.4%; 95% CI: 28.5-40.2) 14,15 . This difference may refl ect differences in the rates of risky behaviors between the studied groups in Goiânia and Santos.…”

introduction:The collection of recyclable waste materials is a widespread activity among the urban poor. Today, this occupation attracts an increasingly large number of individuals. Despite its economic and environmental importance, this activity is associated with unsafe and unhealthy working conditions. The aim of this study was to investigate the seroepidemiological profi le of hepatitis B virus (HBV) infection in a population of recyclable waste collectors in central Brazil. Methods: Recyclable waste collectors from all 15 recycling cooperatives in Goiânia City were invited to participate in the study. The participants (n = 431) were interviewed and screened for hepatitis B surface antigen (HBsAg) and antibodies against HBsAg (anti-HBs) and hepatitis B core antigen (anti-HBc) by enzyme-linked immunosorbent assay (ELISA). HBsAg-and anti-HBc-positive samples were tested for HBV DNA and genotyped. Results: The overall prevalence of HBV infection (HBsAg-and/or anti-HBc-positive) was 12.8%. An age over 40 years and illicit drug use were associated with HBV infection. HBV DNA was detected in 2/3 HBsAg-positive samples and in 1/52 anti-HBc-positive/HBsAg-negative samples (an occult HBV infection rate of 1.9%), in which the genotypes/subgenotypes A/A1, D/D3 and F/F2 were identifi ed. Only 12.3% of the recyclable waste collectors had serological evidence of previous HBV vaccination. Conclusions: These fi ndings highlight the vulnerability of recyclable waste collectors to HBV infection and reinforce the importance of public health policies that address the health and safety of this socially vulnerable population.

“…In addition, unprotected sex with multiple partners was associated with HCV infection according to the univariate analysis of data obtained from the study population. These sexually risky behaviours have been reported by other authors (Terrault 2002, Wang et al 2007, Alter 2011) and appear to be common in this population (Rozman et al 2007, 2008). It should be stressed that most preventative policies related to STIs are aimed at groups with higher exposure risks and do not include recyclable waste collectors.…”

“…The 1.6% prevalence rate of HCV infection found in these individuals in Goiânia was similar to that observed in a multicentric population-based study in the capital cities of Brazil (1.38%; 95% CI: 1.12-1.64) (MS/SVS 2011). Nevertheless, relative to other Brazilian recyclable waste collector populations, this prevalence was lower than the prevalence reported in Santos (12.4%) (Rozman et al 2007, 2008). This difference may reflect differences in the rates of parenteral and sexually risky behaviours between these populations in Goiânia and Santos.…”

The prevalence of hepatitis C virus (HCV) in a population of recyclable waste collectors (n = 431) was assessed using a cross-sectional survey in all 15 cooperatives in the city of Goiânia, Central-West Brazil. The HCV prevalence was 1.6% (95% confidence interval: 0.6-3.6) and a history of sexually transmitted infections was independently associated with this infection. HCV RNA (corresponding to genotype 1; subtypes 1a and 1b) was detected in five/seven anti-HCV-positive samples. Although the study population reported a high rate (47.3%) of sharps and needle accidents, HCV infection was not more frequent in recyclable waste collectors than in the general Brazilian population.

Objectives:Work-related health and safety risks are common among waste management workers (WMWs). This study investigated the level of compliance with safety measures in relation to levels of inflammatory markers among WMWs in Sagamu, South-West Nigeria.Materials and Methods:WMWs comprising 30 cart pushers (CPs) and 50 truck users (TUs) were recruited alongside 45 people from the normal population as control. Data on health complaints were obtained from questionnaire surveys. Inflammation was assessed by measuring plasma ceruloplasmin (Cp), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and albumin.Results:WMWs exhibited a significantly higher prevalence of respiratory and gastrointestinal symptoms and poor compliance with health and safety measures. Significant (P < 0.001) differences were observed in the use of masks, hand gloves, protective clothing, and footwear between TUs and CPs. ESR, Cp, and CRP increased significantly (P < 0.001) by 145, 28.7, and 42.5% in TUs and by 164, 50.5, and 74.3% in CPs, respectively, relative to control. Negative correlation was observed between use of mask (r = -0.225, P < 0.01), use of gloves (r = -0.184, P < 0.05), and Cp and between ESR and washing of hands with soap (r = -0.185, P < 0.05). The use of goggles (r = +0.285, P < 0.001), washing of hands with soap (r = +0.203; P < 0.01), use of masks (r = +0.317, P < 0.001), and use of gloves correlated positively in WMWs.Conclusions:A higher prevalence of work-related symptoms and elevated inflammatory markers in WMWs was related to poor compliance with safety measures. ESR and Cp may be useful predictors of occupational hygiene and compliance with safety measures among Nigerian WMWs.
