Today, the Bronx Zoo revealed she has tested positive for coronavirus, but is expected to recover. https://t.co/glzce4VvTU — Animal Planet (@AnimalPlanet) April 5, 2020 Samples from Nadia were taken and tested after the tiger -- and five other tigers and lions at the zoo -- began showing symptoms of respiratory illness, according to the United States Department of Agriculture (USDA). No other animals at the zoo are showing symptoms. 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 Covid-19 testing that was performed on Nadia was performed in a veterinary school laboratory and is not the same test used for people.
