During this Sars-CoV-2 pandemic, people may be concerned that their pets may spread the virus or become sick. It is not very common, but pets and other animals can transmit the virus and become sick. We knew animals can be infected when a tiger tested positive for Covid-19, and since then experts found that cats, dogs, and a few other types of animals can be infected as well. Despite this, the risk of animals transmitting the virus to humans is considered low by the CDC. Most animals with Covid-19 were in contact with an infected person, so the transmission risk between animals is also considered low. The number of confirmed cases among animals is small, but the US Department of Agriculture (USDA) maintains a list of all animals that have tested positive in the United States.
Because of the low risk for animals, there are no extra precautions pet owners must take to prevent their pets from being infected besides not bringing them in contact with a person that has tested positive for Covid-19. If your pet does happen to contract Covid-19 or you think that is a possibility, call your veterinarian before taking any further action. Many infected animals have shown no symptoms, but the ones showing symptoms so far have been mild. In most cases isolating your pet and limiting their exposure to people or other animals is enough unless your veterinarian says otherwise.
There is no evidence that animals play a significant role in spreading Sars-CoV-2, but pets with the virus do pose a small threat. Coronaviruses that infect animals can be spread to a human and then spread to other humans from there, but this is rare. Evidence shows that this outbreak was originally caused by this when an animal, most likely a bat, infected a person in a live animal market. From there the virus mostly spread from person to person. Person to person transmission is the main way this virus spreads so there is not a lot of risk for animals but talk to a veterinarian if you have any concerns.
