[Hepatitis C viruses infection situation in the human population of six provinces in China].
OBJECTIVE
To investigate the seroprevalence of hepatitis C viruse infection in the human population in six regions of Beijing, Heilongjiang, Shandong, Ningxia, Gansu and Sichuan in China.


METHODS
ELISA was used for detecting anti-HCV IgG of the serum samples. All sample were collected in 2006-2008 in six areas.


RESULTS
9538 samples were detected. The total positive rate of anti-HCV was 0.39% (37), 0.23% (3/1328) in Beijing, 0.74% (12/1629) in Heilongjiang, 0.26% (5/1962) in Shandong, 0.1% (1/1000) in Ningxia, 0.44% in Gansu (9/2 037) and Sichuan (7/1582), respectively. The 37 positive samples at the sex were 19 (51.35%) of man and 18 (48.65%) of female. At the age group were 1 (2.70%) of < 10 years old, 5 (13.51%) of 10-19 years old, 4 (10.81%) of 20-29 years old, 6 (16.22% ) of 30-39 years old, 9 (24.32%) of 4049 years old, 12 (32.43%) of > or = 50 years old. The positive samples were detected anti-HAV-IgG, anti-HEV-IgG and HBsAg/ HBcAb /HBeAb. The positive Number was 35 (94.59%), 10 (27.03%) and 2 (5.41%) respectively.


CONCLUSIONS
HCV infection rate in the population was 0.1% -0.74%, 1/3 of > or = 50 years old in HCV positive. Hepatitis C virus co-infection with HAV, HEV and HBV.
