Abstract

Present study reports the etiological spectrum of viral hepatitis in different types of liver diseases in north India.
Sera from a total number of 370 adult patients belonging to various liver diseases were analysed for different
markers of hepatitis virus A, B, C, D and E infections. These sera were also tested to detect Torque Teno Virus
(TTV) infection in them. The results of analysis show hepatitis A virus (HAV) infection to be rare with hepatitis
B virus (HBV) and hepatitis C virus (HCV) as the predominant cause of acute and chronic liver diseases.
Similarly, hepatitis E virus (HEV) infection is quite common in acute viral hepatitis (AVH) and fulminant
hepatic failure (FHF) patients. Hepatitis D virus (HDV) infection could not be detected in these patients.
TTV-DNA was detected in high proportions in all the disease groups. All types of viral hepatitis in these liver
diseases have been discussed for various aspects.
