NAVLE Ferrets

Ferret Canine Distemper Study Guide

Canine distemper virus (CDV) is the most devastating viral disease affecting ferrets, with mortality rates approaching 100% in unvaccinated animals.

Overview and Clinical Importance

Canine distemper virus (CDV) is the most devastating viral disease affecting ferrets, with mortality rates approaching 100% in unvaccinated animals. Despite its name, CDV affects a wide range of carnivores beyond dogs, with ferrets being exquisitely susceptible due to their membership in the Mustelidae family.

This multisystemic disease is characterized by its biphasic presentation, progressing from catarrhal signs (respiratory and dermatologic) to severe neurological manifestations. For the NAVLE, understanding CDV in ferrets is essential as it represents a high-yield topic combining virology, immunology, clinical medicine, and preventive care.
