Abstract Objective To understand the prevalence of hepatitis C virus ( HCV ) infection in sentinel surveillance in Liaoning Province from 2015 to 2019, in order to provide evidence for the precise prevention and control of HCV. Methods The HCV sentinel surveillance data of 5 kinds of populations, including dialyzed patients, patients receiving invasive diagnosis and treatment, family planning outpatients, people receiving physical examination and unpaid blood donators in Liaoning Province from 2015 to 2019 were retrieved, and the HCV positive rates of different years, gender and age groups in the five populations were analyzed. Results There were 26 000 persons surveyed and 61 HCV positive cases were detected from 2015 to 2019. The HCV positive rate was 0.23%. The HCV positive rates of dialyzed patients, patients receiving invasive diagnosis and treatment, family planning outpatients, people receiving physical examination and unpaid blood donators were 0.40%, 0.70%, 0.25%, 0.24% and 0.14%, respectively. The HCV positive rates of dialyzed patients, patients receiving invasive diagnosis and treatment, and unpaid blood donators had significant downward trends ( P<0.05 ). The HCV positive rates of males and females were 0.22% and 0.26%, without any significant difference ( P>0.05 ). The HCV positive rate of people aged above 70 years old was 1.15%, the highest among different age groups. Conclusions The prevalence of HCV infection among the patients with hemodialysis and with invasive diagnosis and treatment is relatively high. The level of HCV antibody of older age groups should be monitored regularly.
