To compare the infection rates and gene subtypes of TTV between Japanese and Chinese. TTV was detected by a semi-nested PCR. The positive samples were sequenced directly. Infection rate of T'TV in normal Chinese was 64%, but in the patients suffered from chronic C hepatitis, the infection rates were 68% in Chinese and 49.1% in Japanese The gene subtype of TTV Gla + 1b in Chinese was 40%, G2a+ 2b 60%; in Japanese TTV Gla+ 1b was 78.6%, G2a+ 2b 21.4%. There were high infection rates of TTV in Chinese and Japanese. The gene subtype distribution of TTV had some difference between Chinese and Japanese.
