Abstract
On the symposium of "Epidemiologic Study for Occurrence of Acute Hepatitis" in the 2006 annual meeting of Chugoku Branch of Japanese Association of Gastroenterology, a total of 1,815 cases of acute hepatitis occurred in recent 5 to 25 years were reported from 15 hospitals in all Chugoku area. As a result, the cause of acute hepatitis was virus in 52%, drug in 14%, autoimmune in 1% and unknown in 33%. In the recent 10 years, a total occurrence of acute hepatitis was reduced by about 15%. The major factor of this reduction was the reduction of hepatitis A. On the other hand, the number of acute hepatitis of unknown cause was increased and that of drug-induced hepatitis was also seen with a tendency of increase. Concerning to the occurrence of acute viral hepatitis in this area, the frequency of hepatitis B became the highest in replacement of hepatitis A, while the rate of hepatitis C remained unchanged. Then, the recent proportion of the cause of acute viral hepatitis was HBV in 45%, HAV in 25%, HCV in 15%, HEV in 1%, and EBV/CMV combined in 15%.
