| Epidemiological comments |
Five tigers and three lions were housed in two enclosures at a zoo. The first tiger showed clinical signs of disease on March 27. By April 3, three additional tigers and all lions were showing clinical signs. Clinical signs consisted of a dry cough and some wheezing; one animal had inappetence. None of the animals were in respiratory distress. The lions and tigers were isolated and no other animals at the zoo have shown any signs of respiratory disease. Samples were collected from the first affected tiger and it was confirmed positive for SARS-CoV-2/COVID-19. The other animals with clinical signs are also presumed to be infected. All animals are stable and are recovering. It is assumed that an asymptomatic zoo employee infected the animals. |
