Distemper in dogs and cats

What is distemper in dogs and cats?

Canine distemper is a highly contagious and often fatal disease that can affect dogs.  It is an airborne virus that is also spread through contact with items like clothing, dog brushes, shared food, shared water bowls or other utensils. It can also be passed on via fresh urine or blood. There is no known cure for distemper and young puppies that have not been vaccinated or older dogs who are unvaccinated are more susceptible to contracting the disease.

Feline distemper is also referred to as Feline Panleukopenia virus (FPV). It is a highly contagious and life threatening disease which affects the intestinal tract and bone marrow and leads to an anaemic condition that leaves the cat susceptible to other illnesses. Feline distemper is also spread through infected blood, faeces, urine or by fleas that are passed on from infected cats.  It can also be spread through water bowls, bedding and food bowls. Feline distemper can also be spread by humans handling infected cats.

There is no risk of cross contamination between dogs and cats in relation to the different strains of distemper, but animals and humans can carry the disease on their bodies and spread it that way.

Symptoms of distemper in dogs and cats

Symptoms in dogs include a high fever, lack of appetite and lack of energy.  The dog may lose weight and become dehydrated.  The disease also affects the respiratory and gastrointestinal organs, resulting in diarrhoea and vomiting.  The dog may also be coughing and sneezing with mucous coming from their nose and eyes.

The later stages of this disease affects the dog’s nervous system, resulting in convulsions and seizures.

Symptoms in cats include vomiting, dehydration, weight loss, high fever and diarrhoea.

Diagnosis of distemper in dogs and cats

Canine distemper may be diagnosed with the following tests:

• Biochemical tests and urine analysis may reveal a reduced number of lymphocytes, the white blood cells that function in the immune system in the initial stages of the disease (lymphopenia).
• A serology test may identify positive antibodies, but this test cannot distinguish between vaccination antibodies and an exposure to a virulent virus.
• Viral antigens may be detected in urine sediment or vaginal imprints.
• Haired skin, nasal mucous, and the footpad epithelium may be tested for antibodies as well.
• Radiographs can only be used to determine whether an infected animal has contracted pneumonia.
• Computed tomography (CT) and magnetic resonance imaging (MRI) scans can be used to examine the brain for any lesions that may have developed.

There are a number of ways that a vet may diagnose feline distemper including:

• Physical examination
• Blood tests
• Urine analysis
• Faecal sampling

Treatment of distemper in dogs and cats

There are currently no viral drugs that can cure canine distemper and sadly, even with symptomatic treatment, the condition may be fatal.  Symptoms of distemper may be treated with medication and antibiotics while dehydration can be treated by the introduction of fluids. The earlier this disease is medically managed the more effective the treatment will be. Sadly, once this disease impacts the nervous system there is no treatment at all.

Similarly, cats can be treated to ensure that their symptoms are alleviated.  This includes fluids for dehydration, medications to stop vomiting and antibiotics to help protect the cat from developing bacterial infections.

Prevalence and prevention

Distemper vaccinations have been available since the 1950s and today the illness has been somewhat contained due to the vaccination programs.

Incidence of canine distemper is highest in dogs that have not been vaccinated against the disease. Young and unvaccinated puppies and those that are not fully vaccinated are vulnerable. Older dogs that have not been vaccinated can also catch distemper if they come into contact with another dog with the disease or through the environment.

Cats are also vulnerable to infection if they have not been vaccinated against FPV.
