[Typing on 5'-terminal noncoding region of hepatitis C virus genome with restrict endonuclease].

We reported typing of the 5'-terminal noncoding region of HepCV genome in 219 patients with hepatitis C using restrict endonuclease. These patients came from different areas of China. The infective percentage of HCV type II was 83%, type III 14%, and mixed type II and III (II/III) 2%. It is indicated that type III and II/III. The constituent rate of HCV subgenome type in different areas was not significantly different.
