what is distemper in raccoons

Distemper in raccoons is a viral disease caused by the canine distemper virus (CDV) , which also affects dogs, foxes, skunks, and other mammals. It attacks the respiratory, gastrointestinal, and nervous systems, often leading to severe neurologic signs and death in raccoons.

What CDV is in raccoons

Canine distemper virus is a highly contagious paramyxovirus that circulates in wild raccoon populations and can spill over to unvaccinated dogs (and vice versa).

It is considered one of the leading causes of death in raccoons and may cause localized outbreaks when many animals are crowded together.

How it spreads

CDV spreads mainly through inhalation of infected droplets (sneezing, coughing) and contact with contaminated saliva, urine, feces, or surfaces.

The virus can survive for days to weeks in cool, shady environments , making it easy to transmit in shared dens or feeding areas.

Common signs in raccoons

Symptoms can vary, but many sick raccoons show:

• Neurologic issues: circling, stumbling, seizures, “walking on hot stones,” or partial paralysis.

• Behavior changes: disorientation, lethargy, fearlessness (approaching people), or lying in open, exposed areas instead of hiding.

• Respiratory / systemic signs: nasal and eye discharge, fever, coughing, vomiting, diarrhea, unkempt fur, and weight loss.

Human and pet risks

• Humans are not infected by canine distemper, so direct health risk to people is very low.

• Unvaccinated dogs and other canids can be infected, so pets should be up‑to‑date on their distemper‑containing vaccines if raccoons are common in your area.

Outbreaks and “trending” cases

Recent years and early 2026 have seen several local reports of raccoon distemper outbreaks in places like the Greater Toronto Area and parts of the U.S., often linked to unusually bold or sick‑acting raccoons in yards or streets.

These outbreaks usually burn out on their own but can be concerning because they may coincide with seasonal changes and high raccoon density , prompting more public questions and wildlife‑control activity.

What to do if you see a sick raccoon

• Do not touch or feed it ; keep pets and children away.

• Report it to local animal control, wildlife rescue, or a conservation agency , which can safely capture and test the animal.

• If you suspect exposure between a wild raccoon and your unvaccinated dog , contact your veterinarian promptly for advice and possible testing.
