Zoonotic Diseases

  • The Ebola virus is very contagious and is transmitted through blood, body fluids, and tissues, but not through air, water, or food. Ebola affects humans, non-human primates, and is carried by fruit bats. Other species do not appear to be affected, although there has been evidence of exposure to the disease in dogs, cats, and other domestic animals. Domestic animals are not believed to transmit the virus; however, there is a risk that they could transmit body fluids such as saliva on their fur to other humans. Any potential exposure to Ebola should be reported to your veterinarian who will contact the Center for Disease Control (CDC).

  • H1N1 influenza virus emerged in pigs as a genetic sharing of DNA from both human and swine influenza viruses. It caused a deadly pandemic in 2009 and continues to be an important cause of illness today. Pets including cats and dogs can be infected from their owners and become ill. It is not yet known to transfer from pets to humans. Good hygiene and restricted exposure should be taken immediately if there is any sign of influenza-like infection to restrict spread between humans, and between humans and their pets or domestic animals.

  • Tularemia is an infection of the bacteria Francisella tularensis and is most common in rabbits and rodents. Infection in cats occurs from ingestion of an infected animal, drinking contaminated water, or getting bitten by a blood-sucking insect. Clinical signs include enlarged lymph nodes and draining abscesses. Treatment includes antibiotics, surgical removal of any draining abscesses, and any other supportive care warranted by the cat's condition. Tularemia is a reportable zoonotic disease.

  • Tularemia is an infection of the bacteria Francisella tularensis and is most common in rabbits and rodents. Infection in dogs occurs from ingestion of an infected animal, drinking contaminated water, or getting bitten by a blood-sucking insect. Tularemia causes mild illness in healthy dogs. More severe clinical signs include enlarged lymph nodes and draining abscesses. Treatment includes antibiotics, surgical removal of any draining abscesses, and any other supportive care warranted by the dog's condition. Tularemia is a reportable zoonotic disease.

  • The West Nile Virus (WNV) is transmitted by the bite of a mosquito (primarily Culex species) that is infected with the virus. Birds are both susceptible to the virus and can act as a host, though indigenous birds such as owls, hawks, eagles, crows, and jays appear to be most at risk in comparison to pet birds. There is no specific treatment once a bird is infected so prevention is of high importance.

  • Whipworms are intestinal parasites measuring about 1/4 inch (6 mm) in length. They live in the intestinal tract of cats where they can cause severe irritation. Whipworm infection results in watery diarrhea, weight loss, and general debilitation. Fecal testing will not detect every infection. Whipworm infection in cats is rare in North America but cases appear to be rising.
