Signs of infections include periorbital swelling, respiratory signs such as gasping (difficulty in breathing), rales may also be observed. More often, greenish diarrhea is present. Mortality can reach up to 100% Other sings include depression and drooping of the wings, torticollis or twisting of the neck.

Disease Transmission

ND is transmitted through infected or contaminated feces. Bird to bird transmission is often observed. Mechanical vectors can also carry the virus such as farm personnel/ visitors, vehicle, other animals within the farm.
