In recent years, in the study of prevention and treatment of hepatitis B, some animal models similar to HBV have been found in foreign countries: groundhog hepatitis virus (WHV), ground squirrel hepatitis virus (GSHV) and duck hepatitis virus (DHBV) Viroid viruses, represented by HBV to form a new family of viruses, called Hepadnaviridae, have similar structural and biological properties to HBV and are used as animal models of viral hepatitis to be studied.
