Objective: To better understand and measure the status of hepatitis C virus (HCV) infection, we conducted a sero-epidemiological study using the remaining blood samples and data of the nationwide survey of hepatitis B in Chinese residents which was carried out in 2006.
Methods: The anti-HCV reagent was screened out from the reagents by the HCV infection blood serum plate with anti-HCV positives or negatives. This plate recognized the Murex 3.0 and Ortho 3.0 reagents as gold standards. Anti-HCV in the blood samples were tested using this reagent and confirmed by Chiron HCV RIBA 3.0 reagents.
Results: Among the population aged 1 year to 59 year-olds, the overall prevalence rate of anti-HCV was 0.43% (95%CI: 0.33% - 0.53%), with the rates of anti-HCV among males and females as 0.46% and 0.40%, respectively. The prevalence rate of anti-HCV in urban area was 0.43%, and in rural area it was 0.43%. The prevalence rate of anti-HCV in the Eastern, Middle and Western areas were 0.37% (95%CI: 0.21% - 0.53%), 0.67% (95%CI: 0.40% - 0.94%) and 0.31% (95%CI: 0.20% - 0.42%) respectively. The prevalence rates of anti-HCV for the three areas did not show significant differences, statistically. The prevalence rate of anti-HCV in the South and North areas were 0.29% (95%CI: 0.21% - 0.52%) and 0.53% (95%CI: 0.38% - 0.64%) respectively.
Conclusion: Our data revealed that China was in the low prevalence area for hepatitis C infection and the results also suggested that the comprehensive measures for HCV control and prevention had been successfully achieved in the country.
