Nadia, a tiger at the Bronx Zoo in New York, has become the first of her kind to test positive for the coronavirus.
“Though they have experienced some decrease in appetite, the cats at the Bronx Zoo are otherwise doing well under veterinary care and are bright, alert, and interactive with their keepers,” the zoo said.
“It is not known how this disease will develop in big cats since different species can react differently to novel infections, but we will continue to monitor them closely and anticipate full recoveries.”
The animals were infected by a zoo employee who was “asymptomatically infected with the virus” while caring for them, according to the zoo. The Bronx Zoo has been closed to the public since March 16.
Anyone sick with the coronavirus is being advised to minimize contact with animals, including pets, until more information is known about the virus, the USDA said.
