Title Hepatitis E, Helicobacter pylori and peptic ulcers in workers exposed to sewage: A prospective cohort study
Bibliographic information Jan. 2009, Vol.66, No.1, p.45-50. Illus. 34 ref.
Abstract Workers exposed to sewage may have an increased risk of infection by Helicobacter pylori and hepatitis E virus (HEV). To assess the incidence of clinical hepatitis E and peptic ulcers and the seroconversion rate of antibodies to H. pylori and HEV in workers with and without sewage exposure, 332 workers exposed to sewage and a control group of 446 municipal manual workers entered a study with clinical examination and determination of antibodies to H. pylori and HEV. Findings are discussed. Overall, sewage does not appear to be a source of occupational infection by H. pylori or HEV in trained sewage workers with personal protective equipment working in a region with good sanitation infrastructure.
