Title Increased risk of hepatitis E in sewage workers from India
Bibliographic information Nov. 2003, Vol.45, No.11, p.1167-1170. 20 ref.
Abstract Considering faeco-oral transmission of hepatitis E virus (HEV), the risk of infection was assessed among sewage workers. The study involved 147 sewage workers and age-matched controls without exposure to sewage. IgG-anti-HEV positivity in enzyme-linked immunosorbent assay was significantly higher among sewage workers (56.5%) than among controls (19%). Furthermore, a significant rise in anti-HEV positivity was observed among sewage workers working for over five years. Multivariate regression analysis identified contact with sewage as the independent variable associated with anti-HEV positivity. Strict adherence to good working practices must take the top priority for the protection of these workers from sewage pathogens.
