Title Comparative study of the HAV seroprevalence among water purification station workers, sewage workers and administration workers
Original title Enquête comparative de séro-prévalence de l'hépatite A entre les professionnels d'une station d'épuration, de l'assainissement et administratifs [in French]

Abstract An HAV seroprevalence study was conducted among 390 water-purification station workers, 201 sewage workers, and 643 non-occupationally exposed administrative workers. All workers were male, with similar age and socio-educational characteristics. After correcting for age, the rate of hepatitis A seroconversion for all populations was about 69%. Occupational exposure to sludge and sewage were the most important transmission risk factors for hepatitis A. Water-purification station workers exposed to soiled earth polluted with sludge were subject to major risk of hepatitis A transmission with an odds ratio of 1.85. For sewage workers, contact with floating corpses appeared to be an increasing occupational risk for hepatitis A, with an odds ratio of 1.59. A multivariate analysis was also performed to determine the characteristics of the exposed groups and evidence certain patterns of hepatitis A exposure. Vaccination against hepatitis A appears to be the best way to fight against this biological risk, although hygiene and safety measures must not be overlooked.
