Objective To investigate transfusion transmitted virus (TTV) infection among population of different groups in Shaanxi Province.Methods A nested polymerase chain reaction (PCR) with primers from ORF1 of TTV genome was established to detect TTV DNA in serum of the patients.Results TTV DAN was detected in the sera of 3 of 50 cases of general population(6%), 2 of 30 cases of vocational blood donors(6.7%),21 of 97 cases with Type B hepatitis(21.6%),9 of 35 cases of Type C hepatitis (25.7%),and 23 of 40 cases with non A~non G hepatitis(57 5%).Conclusion There is TTV infection among general population in Shaanxi Province.TTV may be an important agent to cause non A~non G hepatitis .And the patients with HBV or HCV can have overlapping TTV infection.
