    Author: Daniel HD, Warier A, Abraham P, Sridharan G.
    Journal: Am J Trop Med Hyg; 2004 Nov; 71(5):675-8. PubMed ID: 15569803.
    Abstract:
    To determine the age-stratified exposure to hepatitis E virus (HEV) in patients attending a tertiary care hospital in southern India, serum samples from 600 individuals were tested using a commercial HEV IgG enzyme-linked immunosorbent assay. Subjects were composed of blood donors, antenatal women, and pre-operative individuals who were negative for hepatitis B surface antigen and antibody to hepatitis C virus with no evidence of liver disease; 200 each were 1-5 and 6-15 years old and 100 each were 16-40 and > or = 41 years old. One (0.5%) sample was positive in those 1-5 years old, two (1.0%) in those 6-15 years old, eight (8%) in those 16-40 years old, and 13 (13%) in those > or = 41 years old. The overall seropositivity rate was 4%. However, there was an age-related increase in exposure to HEV that was statistically significant (P < 0.001), with a higher HEV seropositivity in urban individuals.
