To compare the application of nucleic acid and enzyme immunoassay adopted in HCV screening of volunteer blood donors in Qingyang City. The characteristics of positive population and the status of co-infection were studied. From 2015 to 2020, the positive rate of HCV detection among blood donors in Qingyang City was 3.2‰. Among the HCV positive co-infections, treponema pallidum (TP) accounted for the largest proportion, followed by alanine aminotransferase (ALT) and HBsAg. Blood donation was mainly based on individual voluntariness, and the main age group was 26-45 years old.

Qingcheng County was higher than Huachi County and other places, while Ning County, Heshui County, Zhenyuan County and Huan County were close. The occupation was dominated by unemployed. Their nationalities were all Han. The overall awareness rate of HCV knowledge in young volunteers was 67.2%. There are more HCV infected people with TP infection in voluntary blood donors, and the cognitive level of HCV knowledge in young volunteers needs to be improved.
