HCV Antibody Positive Rates of Blood Donors in Yamaguchi Prefecture / 日本農村医学会雑誌

The HCV antibody positive rates of blood donors were studied in Yamaguchi Prefecture. C100-3 antibody was examined by the method of the 1st generation. The subjects were 146, 792 people who donated blood from Nov. 1989 to Dec. 1990. The average positive rate was 1.01% in Yamaguchi Prefecture. The positive rates of more than 3% were registered in four towns. In one town out of these four, the average positive rate was 22.0% It was extremely higher than the other three towns. Further study will be required to elucidate such regional differences in the HCV positive rate in the prefecture.
