Joining the global rise in coronavirus cases is a female tiger at the Bronx Zoo in New York City. Nadia, a four-year-old Malayan tiger, worried her zookeepers when she began exhibiting a dry cough and a loss of appetite on 27 Mar 2020.
After the zoo employees sent her samples to Cornell University, the University of Illinois, and the USDA National Veterinary Services Laboratory, Nadia was confirmed to be the first non-domesticated animal in the world to test positive for COVID-19.

Six other large cats at the zoo showed similar signs of respiratory illness as well. Nadia’s sister Azul, two Siberian tigers, and three African lions also suffered a loss of appetite and a dry cough, leading the zookeepers to suspect that they, too, have the coronavirus.
Since the Bronx Zoo closed its doors to visitors starting 16 Mar 2020, Dr. Paul Calle, chief veterinarian for the Wildlife Conservation Society, believes that the animals contracted the virus from an asymptomatic caretaker.
