In early January, several gorillas at this southern California zoo, one of the largest in the world, had tested positive for the new coronavirus and placed in quarantine after showing symptoms. This was the first known case of natural transmission of the virus to great apes. They have since recovered.
The following month, four orangutans and five bonobos at the San Diego Zoo each received two doses of an experimental vaccine developed by the specialist firm Zoetis.
