objective:to find out the problems in diagnosis and case report and to provide useful information for standardization of viral hepatitis diagnosis and report by analyzing the reported viral hepatitis cases in taixing. methods:the clinical and laboratory classification of the viral hepatitis patients reported in taixing during 2005~2009 were collected and analyzed with excel 2007 and spss 13.0 retrospectively. results:the reported incidence rate of viral hepatitis was 31.01/100 000~46.63/100 000 during 2005~2009,which showed an increased trend. the incidence of chronic hepatitis b in adult was obviously unstable;the incidence of hepatitis b without classification was 6.25/100 000~13.40/100 000,accounting for 31.0%~70.2% of total. compared to 2005,the incidence of hepatitis c increased(linear trend χ2=82.04,p < 0.01) while the hepatitis a decreased gradually(linear trend χ2=6.10,p < 0.05). the non-abc hepatitis accounted for 16.6%~23.0% of hepatitis. according to medical records and laboratory testing,the percentage of correct diagnosis of hepatitis a and e was 66.7%(12/18). the classification coincidence rate of hepatitis b was 51.35%(19/37). most hepatitis c patients[68.42%(13/19)] were anti-hcv positive without symptoms. more than half of non-abc hepatitis(53.97%) could be reclassified. conclusion:the reported incidence of chronic hepatitis b in taixing during 2005~2009 was unjustified,this point out that the reported incidence of hepatitis was inaccurate and the accuracy of categorization,classification of hepatitis should be improved.
