Title Prevalence of antibody to hepatitis A virus in drinking water workers and wastewater workers in Texas from 1996 to 1997
Bibliographic information Aug. 2000, Vol.42, No.8, p.821-826. 18 ref.
Abstract To determine if wastewater workers had a higher prevalence of antibody to hepatitis A virus (anti-HAV) than drinking-water workers, 359 wastewater and 89 drinking-water workers were evaluated for risk factors by questionnaire and tested for anti-HAV. Anti-HAV positivity was 28.4% for wastewater and 23.6% for drinking-water workers. After adjustment for age, educational attainment and Hispanic ethnicity, the odds ratio for the association between anti-HAV positivity and wastewater industry employment was 2.0. Among wastewater workers, never eating in a lunchroom, ≥8 years in the waste water industry, never wearing face protection, and skin contact with sewage at least once per day were all significantly associated with anti-HAV positivity. Wastewater workers had a higher prevalence of anti-HAV than drinking-water workers, which suggested that wastewater workers may have been at increased risk of occupationally acquired hepatitis A.
