Washington, D.C., February 10, 2021 -- The United States Department of Agriculture’s (USDA) National Veterinary Services Laboratories (NVSL) today announced confirmation of SARS-CoV-2 (the virus that causes COVID-19) in a cougar at a facility that exhibits wild animals in Texas. This is the first cougar in the United States to be confirmed positive for SARS-CoV-2. A tiger from the same facility was also confirmed positive for the virus.
Samples from several animals at the facility were taken after showing clinical signs including coughing and wheezing. The animals are expected to fully recover. It is suspected that the large cats acquired the infection from a person working as a team member or volunteer who was positive for COVID-19.
SARS-CoV-2 infections have been reported in a small number of animals worldwide, mostly in animals that had close contact with a person with COVID-19. At this time, routine testing of animals is not recommended. State and local animal health and public health officials will work with USDA and the U.S. Centers for Disease Control and Prevention (CDC) to make determinations about whether animals should be tested for SARS-CoV-2, using a One Health approach.
USDA will announce cases of confirmed SARS-CoV-2 in animals each time the virus is found in a new species. Confirmed cases in animals are updated weekly and are posted at https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/sa_one_health/sars-cov-2-animals-us.
All testing on the samples was conducted at NVSL. NVSL serves as an international reference laboratory and provides expertise and guidance on diagnostic techniques, as well as confirmatory testing for foreign and emerging animal diseases. Such testing is required for certain animal diseases in the U.S. in order to comply with national and international reporting procedures. The World Organisation for Animal Health (OIE) considers SARS-CoV-2 an emerging disease, and therefore USDA must report confirmed U.S. animal infections to the OIE.
While additional animals may test positive as infections continue in people, it is important to note that performing this animal testing does not reduce the availability of tests for humans.
We are still learning about SARS-CoV-2 in animals, but there is currently no evidence that animals play a significant role in spreading the virus to people. Based on the information available, the risk of animals spreading the virus to people is considered to be low.
People with COVID-19 can spread the virus to some animals during close contact. It is important for people with suspected or confirmed COVID-19 to avoid contact with pets and other animals to protect them from possible infection.
