Adding to the confusion of coronavirus is the weekend revelation that a tiger at the Bronx Zoo has tested positive. This development now has many wondering about their pets.

“I couldn’t believe it,” zoo director Jim Breheny said in an Associated Press article about the tiger. “Any kind of knowledge that we get on how it’s transmitted, how different species react to it, that knowledge somehow is going to provide a greater base resource for people.”

What steps do pet owners take? Both the American Veterinary Medical Association and the federal Centers for Disease Control and Prevention have been recommending that out of an abundance of caution, people ill with the coronavirus should limit contact with animals — advice that the veterinary group reiterated after learning of the tiger’s test result. In general, the CDC also advises people to wash their hands after handling animals and do other things to keep pets and their homes clean.

There’s still a lot for us all to learn about COVID-19. This is yet one more example.
