Results The positive rate of anti-HCV in anti-HCV was 5.72% in 2 849 ethnic minority blood donors. The positive rate of anti-HCV was 1.61%, the positive rate of anti-HIV was 0% and the positive rate of anti-TP was 0.84%. Conclusions According to the fourth census data, the population of blood donors in our province is 2.4 million. It can be estimated that there are 130,000 hepatitis B carriers, 37,000 hepatitis C carriers and 21,000 syphilis carriers, 8% of the total number of blood donors at the same age, further illustrating the lack of voluntary blood donation in our province, the precious blood resources.
