Key result
TT virus DNA positivity was 6.7% in chronic hepatitis patients, 24.4% in hemophiliacs, and 7.4% in blood donors, indicating it is not an important cause of chronic liver diseases in India.

In India, TTV is transmitted mainly by nonparenteral routes and does not appear to be an important cause of chronic liver diseases.
In western India, TT virus (TTV) DNA positivity varied from 6.7% (5 of 75) in chronic hepatitis patients to 24.4% (10 of 41) in hemophiliacs; 7.4% (4 of 54) of voluntary blood donors had circulating TTV DNA. Phylogenetic analysis revealed a predominance of genotype 1a. In India, TTV is transmitted mainly by nonparenteral routes and is not an important cause of chronic liver diseases.
