Two gorillas at a California zoo have tested positive for COVID-19, in what is believed to be the first known cases of the virus among great apes, officials said Monday.
The San Diego Zoo Safari Park said the gorillas started coughing on Wednesday, prompting officials to test their stool samples, which came back positive for the coronavirus.
“Aside from some congestion and coughing, the gorillas are doing fine,” Lisa Peterson, the zoo’s director, said in a statement.
“The troop stays together in quarantine and eat and drink,” said Peterson. “We hope for a full recovery.”
Officials believe the primates contracted the virus from an asymptomatic staff member, “despite following all recommended precautions,” the zoo said in a press release.
“This is the first known case of natural transmission to great apes and it is not known if they will have a serious response,” the statement said.
In an update on the coronavirus pandemic Monday, California Governor Gavin Newsom said a third gorilla was also showing symptoms of the disease.
“We are currently confirming the source of the infection and the strain,” Newsom said.
‘There is a question as to whether it has gone from human to animal. That is determined…, ”he added.
The virus has also been found in cats, dogs, a lion and a tiger, as well as mink, which officials say appears to be the most sensitive animal to date.
