Aviadenoviruses are adenoviruses that affect birds—particularly chickens, ducks, geese, turkeys and pheasants. One of these viruses, EDS ’76 causes important disease in birds, notably chickens, ducks, geese and swans. It is characterised by a sudden drop in production of eggs as well as its eggshell quality in apparent healthy laying birds.
The natural host of Duck atadenovirus A are wild and/or domestic waterfowls such as ducks and geese. However, the virus can also infect other bird species through contaminated vaccines, and contaminated drinking water by droppings.
