Transmitted from duckling to duckling and from infected environment to duckling. Spreads rapidly within the pen; the virus is excreted in feces. Most poultry species other than chickens and turkeys can be infected. Lesions are swollen mottled liver, enlargement of spleen or kidney, or both. Morbidity is 100%, while mortality is variable. In broods less than 1 wk old mortality can be 95%, 1-3 wks old mortality is 50% or less, and more than 4 wks old mortality is negligible. Diagnosis is by history, pattern of disease, and direct FA techniques. Can be treated by antiserum injection from immune ducks. Prevent by vaccination and by strict isolation, especially during the first 4-5 wks.
