Three gorillas have tested positive for the novel coronavirus, according to a recent U.S. Animal and Plant Health Inspection Service announcement. Two of the primates began coughing, prompting testing for all eight gorillas at the San Diego Zoo. Three of the primates tested positive for SARS-CoV-2, the disease that causes COVID-19 in humans. Authorities suspect the animals contracted the disease from an asymptomatic staff member even though the zoo took safety precautions. All three gorillas are expected to fully recover, APHIS said. The gorillas add to a growing list of zoo animals that have now contracted SARS-CoV-, including tigers (Panthera tigris), lions (Panthera leo) and snow leopards (Panther uncia).
