Two hyenas at the Denver Zoo have tested positive for the coronavirus, the first confirmed cases among the animals worldwide, a national veterinary lab announced Friday, reports U.S.News.
Hyenas tested positive
Samples from a variety of animals at the zoo, including the spotted hyenas, were tested after several lions at the facility became ill, according to the National Veterinary Services Laboratories. The hyena samples tested presumptive positive at a lab at Colorado State University, and the cases were confirmed by the national lab.
Hyenas are famously tough, resilient animals that are known to be highly tolerant to anthrax, rabies and distemper.
Symptoms
Zoo officials said the hyenas — 22-year-old Ngozi and 23-year-old Kibo — are experiencing mild symptoms, including slight lethargy, some nasal discharge and an occasional cough.
Other animal’s condition
The other animals that tested positive in recent weeks have either fully recovered or are on the path to a full recovery. 11 lions and two tigers at the zoo tested positive for the virus.
“We now know that many other species may be susceptible to COVID-19 based on multiple reports, and we continue to use the highest level of care and precaution when working with all of our 3,000 animals and 450 different species,” the statement said.
Infections have been reported in multiple species worldwide, mostly in animals that had close contact with a person with COVID-19, according the the United States Department of Agriculture, which oversees the NVSL.
Not much information available about coronavirus infections in animals
A news release Friday said scientists are still learning about coronavirus infections in animals, but based on the information available, the risk of animals spreading the virus to people is low.
