The naming of duck viral hepatitis (DVH) was not a problem when the causative virus has been firstly identified. However, during the past seventy years, there are 14 hepatotropic viruses among 10 different genera that are associated with the same disease name, DVH. This complexity largely challenged scientific communication of the disease, as well as the causative virus. In order to address this nomenclature problem, in this proposal, we revisited the problem and proposed an update to DVH disease classification. This new classification is based on the nomenclature of human viral hepatitis and the key principle of Koch's postulates. In total, we proposed 10 types of disease names which were literately matched with hepatitis-related viruses. We envision that this intuitive nomenclature system will facilitate scientific communication and consistent interpretation in this field, especially in the Asian veterinary community, where these diseases are most commonly reported.
