Epizootic Catarrhal Enteritis (ECE)

What is it?
ECE is a contagious intestinal infection caused by a ferret coronavirus. It often appears when a new ferret joins the household; young ferrets may carry it and show mild signs while older ferrets get sicker.
What signs should I watch for?
Signs to watch for include bright green, slimy diarrhea; vomiting; poor appetite and lethargy; dehydration and weight loss; and seedy-looking stools later on.
How is it diagnosed and treated?
Diagnosis is based on history and signs; lab tests can help. Treatment is supportive: fluids, nutrition, and medications to protect the gut and prevent secondary infection.
Can it be prevented, and what's the outlook?
- Most ferrets recover with care, though older ferrets are at greater risk.
- Quarantine new ferrets and practice good hygiene.
