Four tigers and three lions have tested COVID-19 positive at the Bronx Zoo in New York, authorities announced, weeks after a Malayan tiger at the facility was confirmed positive and six other big cats were said to be exhibiting similar symptoms. On April 5, the Wildlife Conservation Society that runs the New York zoo, reported that one tiger had tested positive for the new coronavirus, the first known COVID-19 infection found in a big cat, reports Efe news.

The first big cat, a four-year-old Malayan tiger named Nadia, developed a dry cough and loss of appetite in late March, while Nadia's sister Azul, two Amur tigers, and three African lions also showed the same symptoms. "We can confirm that the three other tigers in Tiger Mountain and the three African lions that exhibited a cough have also tested positive for COVID-19," the zoo said in a statement on Wednesday.
