Newcastle disease (ND) is a highly contagious, generalized viral disease of domestic poultry, caged and aviary birds, and wild birds but also seen in domestic poultry when highly virulent as a rapidly fatal, high-mortality condition characterized by gastrointestinal, respiratory and/or nervous signs. ND viruses have a varying capability to produce clinical disease in domestic chickens, with some virus strains showing high levels of pathogenicity. The World Organization for Animal Health (OIE) has defined ND as the disease caused by Newcastle viruses whose high and moderate pathogenicity is demonstrated in tests on chickens. Vaccination and biosecurity are considered the best remedies in the prevention and control of the disease in domestic poultry.

WHAT YOU’LL LEARN:
1. Infection of domestic poultry with ND virus contributes to decreased productivity.
2. Infected birds shed virus in exhaled air, respiratory discharges, and feces.
3. Movement of infected birds transmits virus.
4. Monitoring the immune status of a poultry flock.
