Risk of airborne transmission of avian influenza from wild waterfowl to poultry negligible


Recommended Posts

Research by Wageningen Bioveterinary Research (WBVR) has shown that the risk of airborne transmission of high pathogenic avian influenza virus from infected wild birds is negligible. The research looked specifically at the airborne movement of particles from wild waterfowl droppings in the vicinity of poultry farms during the risk season for avian influenza (October to March). It also considered transmission via aerosolization, with the exhalations or coughs of wild waterfowl infected with avian influenza virus finding their way into the ventilation systems of poultry farms. As a precaution, it's important that the carcasses of wild waterfowl or other wild birds that have died of high pathogenic avian influenza are removed from their habitat as soon as possible. If not, scavengers eating the carcasses could cause feathers to become distributed. Feathers of wild birds that died of, and if the wild bird died of high pathogenic avian influenza contain the virus, which can then the virus can survive for a long time in those feathers.
