Several gorillas at the San Diego Zoo Safari Park have tested positive for the coronavirus in what is believed to be the first known cases among such primates in the United States and possibly the world. The park’s executive director, Lisa Peterson, told The Associated Press that eight gorillas that live together at the park are believed to have the virus and several have been coughing. It appears the infection came from a member of the park’s wildlife care team who also tested positive for the virus but has been asymptomatic and wore a mask at all times around the gorillas.
