What causes Newcastle Disease?
Newcastle Disease is caused by a Paramyxovirus. It is very resistant and survives a pH of 2 to 12, heating to 130° F (56° C) for 3 hours, and can survive freezing indefinitely. Extended drying and ultraviolet light will kill the virus. END virus can survive for several weeks in the warmth and humid environment of a poultry production unit on feathers, in manure, and other materials.
