Two gorillas at a California zoo have tested positive for COVID-19, which is believed to be the first known cases of the virus among great apes, officials said Monday.
The San Diego Zoo Zoo said gorillas began coughing Wednesday, prompting officials to test their fecal samples, which tested positive for coronavirus.
“Aside from some congestion and coughing, the gorillas are doing well,” zoo director Lisa Peterson said in a statement.
“The troops are still in quarantine together and eating and drinking,” Peterson said. “We look forward to a full recovery.”
Officials believe the primates caught 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 unknown if they will have any serious reaction,” the statement said.
California Gov. Gavin Newsom said Monday in an update to the coronavirus pandemic that a third gorilla was also showing symptoms of the disease.
“We are currently confirming the origin of the infection and the strain,” Newsom said.
“Are there any questions about whether it came from man to animal? That is being determined … “, he added.
The virus has also been found in cats, dogs, a lion and a tiger, as well as in minks, according to officials who appear to be the most susceptible animal to date.
