| molecular confirmation of hepatitis a virus from well water: epidemiology and public health implications. | 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 ... | 1999 | 9841820 |
