OBJECTIVE: To investigate the seroprevalence of hepatitis viruses in Mianyang of the Sichuan province. METHODS: EIISA was used for detecting anti-HAV IgG, HBsAg/HBsAb, anti-HCV IgG and anti-HEV IgG of the serum samples. All sample were collected in Mianyang areas in 2007. RESULTS: 1352 samples were detected. The positive rates of anti-HAV, HBsAg/HBsAb, anti-HCV,and anti-HEV are 81.07% (1096/1352), 5.40% (73/1352) and 61.32% (829/1352), 0.37% (5/1352) and 49.26% (666/1352), respectively. The positive rate at different age group, for anti-HAV was 38.21% of 10-19 years old, 83% of 20-29 years old, 88% of 30-39 years old, 95.03% of 40-49 years old, 97% of 50-59 years old, 97.77% of 60-69 years old, 97.52% of > or =70 years old. For HBsAg/HBsAb were 5.65% or 50.83%, 10.0% or 68.0%, 5.20% or 78.80%, 5.97% or 78.11%, 6.50% or 62.50%, 1.12% or 51.40%, 4.96% or 30.58% at the same age group, respectively,for anti-HCV, was 0.33% of 10-19 years old, 0.80% of 30-39 years, 0.56% of 60-69 years old, 0.83% of > or =70 years old.For HEV-IgG was 26.58% of 10-19 years old, 42.0% of 20-29 years old, 55.22%-61.0% of 30-> or =70 years old, for anti-HEV IgM, was 10.06% (53/527) in the positive samples of HEV-IgG. CONCLUSION: The inoculation againt HAV and HBV is enhanced in the young population. HBsAg carrier and HCV infection is decreasing. The HEV infection is actually increasing.
