Abstract:
Objective: To analyze the changing trend and distribution characteristics of hepatitis C virus (HCV) infection among blood donors in Hebei, thereby providing data to support strategy and procedure adjustment for blood collection and supply institutions. Methods: Data from 12 blood stations in Hebei Province from 2012 to 2021 were collected. These data were analyzed to determine trends in anti-HCV antibody double reagent reactive rate and to characterize its distribution among different donor categories, genders and birth cohorts. Results: During the period from 2012 to 2021, a total of 7.4576 million samples were tested at 12 blood stations in Hebei Province, with 3.4659 million (46.47%) from first-time donors, and 3.9917 million (53.53%) from repeat donors. The number (of anti-HCV double reagent reactive samples was 7167 (9.61/10 000). The anti-HCV double reagent reactive rate showed a annual downward trend (P<0.05), from 17.40/10 000 at the beginning to 4.95/10 000 at the end of the study period. Additionally, the double reagent reactive rate of repeat blood donors had remained below 1/10 000 since 2017. The double reagent reactive rate of first-time blood donors (19.42/10 000) was higher than in repeat donors (1.09/10 000) (P<0.05), and the double-reagent reactive rate of female first-time blood donors (20.98/10 000) was higher than that of male first-time blood donors (18.49/10 000) (P<0.05). The anti-HCV double reagent reactive rate among first-time donors exhibited two distinct peaks within the pre-1976 and 1989-1994 birth cohorts, with notable gender differences observed in both peak periods. The rate of double reagent reactive in females born before 1976 (52.22/10 000) was higher than that in males (32.28/10 000) (P<0.05), while that of males born in 1989-1994 was higher (25.75/10 000) than that of females (14.28/10 000) (P<0.05). Conclusion: The prevalenc of HCV infection among blood donors in Hebei Province has shown a consistent year-over-year decline over the study period. The majority of infected individuals are found among the first-time blood donors born before 1995. These trends and characteristics provide valuable insights for developing pre-blood collection screening strategies, analyzing nucleic acid test data in blood screening, adjusting blood screening procedures, and provide evidence for targeted screening of high-risk populations as part of public health initiatives to eliminate hepatitis C.
