| Alutian Disease |
| Aleutian disease (AD) is caused by a parovirus and is an immune deficiency disease, capable of being transmitted from infected parents to offspring and from infected ferrets to any other ferret via direct or indirect contact. |
| Symptoms vary tremendeously and may include black tarry faeces, weight loss, aggressiveness, recurrent fevers, thyroiditis, posterior paralysis and eventual death; in stressed animals death may occur extremely suddenly. |
| Veterinary advice should be sought for all ferrets thought to be infected or in contact with an infected ferret. |
