Seroepidemiology and role of polymerase chain reaction to detect viremia in an epidemic of hepatitis E in Western India.

Aim: In an outbreak of hepatitis E affecting 859 individuals, we evaluated the titres of serological markers (IgM anti-HEV and IgG anti-HEV) and hepatitis E virus (HEV) RNA by reverse transcriptase polymerase chain reaction.

Methods: Serological markers for acute hepatitis were evaluated in 294 icteric patients (Group A) and 300 apparently healthy controls (Group B). HEV RNA was measured by RT nPCR in 19 patients in the first week of illness in patients with negative IgM anti-HEV.
