An outbreak of AI could be primary (directly from the environment/wild animals) or secondary (from another outbreak) and we must start from here. So, it means that, by one side, it could be effective to avoid any direct or indirect contact of the poultry with wild animals, as, by the other side it could be effective to avoid any direct or indirect contact with other poultry farms. To go more into details I consider that to close poultry into the barn in cases of free range poultry farm, to use antibirds net on the window of the house, to mantein the doors/gates of the barn all time closed, to use properly the farm and the house hygiene lock, to limit the movements into the farm of any trucks or any other means of transport, strictly permitting the access when really necessary and only after an appropriate disinfection at the entrance, are very important measures to adopt. In addition I consider very important also to limit the access of any kind of visitors (vets, technicians, others).
