What are the signs a duck infected with this virus might display?
• There is no prolonged illness associated with DVE and sick birds may not often be seen. The disease progresses very quickly and birds that appear healthy one day may be very sick or deceased the next. A susceptible duck will begin to show signs of DVE three to seven days after they are exposed. Infected birds may exhibit no outward signs or may become lethargic, lose their appetites, become unable to fly, and may have a bloody or foamy discharge from their beak or vent.
