A gorilla at the San Diego Zoo Safari Park in Escondido, Calif., underwent monoclonal antibody therapy after contracting COVID-19 this month.
Winston, an elderly silverback gorilla, and two other troop members tested positive for the coronavirus after they had symptoms such as mild coughing. "The virus was confirmed in 3 gorillas and we assume they all were exposed," Nadine Lamberski, the zoo's chief conservation and wildlife health officer, told NPR in an email. She said all the troop members were managed accordingly.
