Virulent Newcastle Disease (VND), also known as Exotic Newcastle Disease, is a deadly viral disease that affects all species of birds, domestic and wild. VND spreads quickly and can infect and kill poultry. Chickens are the most susceptible poultry; ducks and geese are the least. Bird owners should be aware of the basics, how to help prevent the disease and what to do if an outbreak is suspected.

Virulent Newcastle Disease was discovered in 2018, in a backyard flock on the west coast. The last time it was seen in the United States was in 2003.
