A tiger at the Bronx Zoo is believed to be the first animal in the U.S. and the first tiger in the world to test positive for the new coronavirus.
Nadia, a four-year-old Malayan tiger, was tested for the virus that causes COVID-19 after she developed a dry cough and began to lose her appetite, Reuters reported. Three other tigers and three lions have also developed a cough, though Nadia was the only one tested because she was the sickest and large cats have to be anesthetized for testing.
“I couldn’t believe it,” Zoo Director Jim Breheny told The Associated Press of the positive test result.
He said the zoo had only tested Nadia “out of an abundance of caution.”
Officials believe Nadia caught the disease from a zoo worker who was asymptomatic at the time. The worker had contact with all of the infected animals, who live in two separate areas, and the zoo has been closed to the public since March 16. The infected worker is now doing okay.
In addition to Nadia, her sister Azul, two Amur tigers and three African lions have shown symptoms. The first animal fell ill March 27.
“It’s the first time, to our knowledge, that a [wild] animal has gotten sick from COVID-19 from a person,” chief Bronx Zoo veterinarian Paul Calle told National Geographic.
