A tiger at the Bronx Zoo has been infected with the coronavirus, in what is believed to be a case of what one official called “human-to-cat transmission.”

“This is the first instance of a tiger being infected with Covid-19,” according to the federal Agriculture Department, which noted that although only one tiger was tested, the virus appeared to have infected other animals as well.

“Several lions and tigers at the zoo showed symptoms of respiratory illness,” according to a statement by the department. They are expected to recover.

Public health officials believe that the large cats caught Covid-19, the disease caused by the coronavirus, from a zoo employee.
