Summary:This study was conducted to determine the exposure rate of Hepatitis A and Hepatitis E viruses in urban solid waste collectors/sweepers in the south of Iran. The 385 samples (serums) were collected from Shiraz Municipality waste sweepers.. A questionnaire was used to gather data on their demographic and occupational characteristics, as well as their awareness of viral hepatitis disease. The viral seroprevalence was determined by commercial IgG ELISA kit. All participants were male, mean age of 41 ± 8 years. ELISA assay showed that all of them were positive for anti-HAV IgG. Also, 62 out of 385 individuals were positive for anti-HEV IgG. The statistical analysis showed that the frequency of HEV IgG antibody among age groups 20-30, 31-40, 41-50 and >50 years old had an increasing trend, 4.5%, 10.1%, 17.4%, and 36.7%, respectively, indicating age factor significance (p = .001). Based on some investigated factors including the duration of work experience, current and previous jobs, habitation, personal hygiene status, and knowledge on viral hepatitis diseasees/their transmission, there was no statistically significant difference between anti-HEV IgG positive versus negative sweepers. The results indicated a slighty higher frequency of anti-HAV and anti-HEV IgG among sweepers compared to other pre-investigated population. It doesn't seem that garbage collecting/sweeping could be a significant risk factor for HAV and HEV infection.
