  1. Molecular confirmation of hepatitis A virus from well water : Epidemiology and public health implications.

    Article - En anglais

    An outbreak of hepatitis A in a rural river-island community was found to be associated with consumption of contaminated well water.

    Specimens from case-patients, the implicated well, and a cesspool suspected to be the source of contamination were all positive for hepatitis A virus (HAV) RNA by immunocapture reverse-transcription polymerase chain reaction.

    All isolates were identical over about 400 bases from two capsid-encoding regions of the genome, identifying the chain of transmission.

    Other wells up to 60 m from the cesspool also contained HAV RNA.

    In addition, HAV RNA was detected in the contamination source well 6 months after the initial contamination, when fecal coliform bacteria were no longer present.

    These findings demonstrate the utility of viral detection techniques to evaluate contaminated ground water.
