Coronavirus and Pets

According to the American Veterinary Medical Association, “pets do not appear to be easily infected with SARS CoV-2” and there is no evidence that they can transmit the virus to people under natural conditions. Indeed, as of June 1, 2020, there are fewer than 25 reports of SARS CoV-2 infection in cats and dogs worldwide, in spite of the number of infected people exceeding 6.2 million globally and 1.8 million in the US. Accordingly, routine testing of animals for COVID-19 is not recommended by the AVMA, CDC, USDA, American Association of Veterinary Laboratory Diagnosticians, National Association of State Public Health Veterinarians, or the National Assembly of State Animal Health Officials. For more information, 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.
