Duck viral hepatitis (Duck Viral Hepatitis, DVH) is caused by duck hepatitis virus is an acute, highly lethal infectious disease. The classic type of duck hepatitis A virus can cause disease with symptoms such as duck, necropsy with hepatomegaly and bleeding as the main feature, pancreatitis type duck hepatitis A virus and found in recent years to cause disease in duck pancreatic yellow, bleeding and no obvious liver bleeding as the main feature. In this paper, we reviewed the progress in the study of two different pathogenic strains from the aspects of genome structure, clinical features, pathological changes and diagnostic methods.
