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 anal
ysis revealed a predominance of genotype la. In India, TTV is transmitted m
ainly by nonparenteral routes and is not an important cause of chronic live
r diseases.
