COVID-19 and Pets

According to the One Health Federal Interagency COVID-19 Coordination Group (OH-FICC), as of Aug. 11, 2020:

  • There are currently 31 confirmed cases of SARS-CoV-2 infection in animals in the United States.
  • Of these animals, some have shown signs of illness while others have not appeared sick.
  • There is no evidence that animals, including pets, are playing a significant role in the spread of COVID-19.
  • Based on the limited information available to date, the risk of animals, including pets, spreading COVID-19 to people is considered to be low.
  • If you are sick with COVID-19 (either suspected or confirmed by a test), you should restrict contact with your pets and other animals, just as you would with people.
  • Talk to your veterinarian if your pet gets sick or if you have any concerns about your pet’s health

For more information, read the complete OH-FICC report or visit the AVMA’s COVID-19 in Pet Animals webpage.

If you need to test a pet for COVID-19, please follow the Oklahoma State Veterinarian’s Guidelines for testing companion animals for COVID-19.
