A member of the gorilla troop at the San Diego Zoo Safari Park in Escondido, Calif., soaks in the sun at his habitat on Sunday, Jan. 10, 2021. Several gorillas at the zoo 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. 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.
