A four-year-old tiger at the Bronx Zoo has tested positive for the coronavirus, according to the Wildlife Conservation Society.
OFFICIAL PRESS RELEASE
Bronx NY, April 5, 2020 — The following information was released today by the Wildlife Conservation Society’s Bronx Zoo:
Nadia, a 4-year-old female Malayan tiger at the Bronx Zoo, has tested positive for COVID-19. She, her sister Azul, two Amur tigers, and three African lions had developed a dry cough and all are expected to recover.
This positive COVID-19 test for the tiger was confirmed by USDA’s National Veterinary Services Laboratory, based in Ames, Iowa.
We tested the cat out of an abundance of caution and will ensure any knowledge we gain about COVID-19 will contribute to the world’s continuing understanding of this novel 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. 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 four affected tigers live in the zoo’s Tiger Mountain exhibit. One male Amur tiger that also lives at Tiger Mountain has not exhibited any clinical signs, and a Malayan tiger and two Amur tigers at the zoo’s Wild Asia exhibit have also not exhibited any clinical signs.
None of the zoo’s snow leopards, cheetahs, clouded leopard, Amur leopard, puma or serval are showing any signs of illness. Our cats were infected by a person caring for them who was asymptomatically infected with the virus or before that person developed symptoms. Appropriate preventive measures are now in place for all staff who are caring for them, and the other cats in our four WCS zoos, to prevent further exposure of any other of our zoo cats.
We are grateful for the cooperation and support of the New York State Diagnostic Laboratory at Cornell University and the University of Illinois College of Veterinary Medicine Veterinary Diagnostic Laboratory, where the initial COVID-19 testing of samples from the tiger were performed; the USDA National Veterinary Services Laboratory where confirmatory testing was conducted; USDA Animal and Plant Health Inspection Service; and the New York and Illinois State Veterinarians and the New York City Department of Health and Mental Hygiene for their assistance.
COVID-19 is a disease caused by the coronavirus known as SARS-CoV-2. It is believed that the virus was first transferred to people at a food market that trades in wildlife in Wuhan, China. There is no evidence that animals play a role in the transmission of COVID-19 to people other than the initial event in the Wuhan market, and no evidence that any person has been infected with COVID-19 in the US by animals, including by pet dogs or cats.
We will issue additional information as warranted. Our four zoos and aquarium have been temporarily closed since March 16.
