First cases of COVID-19 discovered in Canadian wildlife

OTTAWA — The first cases of COVID-19 in Canadian wildlife have been discovered in three white-tailed deer, a press release from Environment and Climate Change Canada reports.

The National Centre for Foreign Animal Disease confirmed the detections on Nov. 29 but the deer were sampled between Nov. 6 to 8 in the Estrie region of Quebec. The deer showed no evidence of clinical signs of disease and were “all apparently healthy.”

“As this is the first detection of SARS-CoV-2 in wildlife in Canada, information on the impacts and spread of the virus in wild deer populations is currently limited,” the press release states.

“The finding emphasizes the importance of ongoing surveillance for SARS-CoV-2 in wildlife to increase our understanding about SARS-CoV-2 on the human-animal interface.”

The World Organisation for Animal Health was notified about the discovery on Dec. 1.

The department is urging added precaution – like wearing a well-fitted mask – when exposed to “respiratory tissues and fluids from deer.”

The virus has been found in multiple animal species globally including farmed mink, cats, dogs, ferrets, and zoo animals such as tigers, lions, gorillas, cougars, otters and others.

“Recent reports in the United States have revealed evidence of spillover of SARS-CoV-2 from humans to wild white-tailed deer, with subsequent spread of the virus among deer. There has been no known transmission of SARS-CoV-2 from deer to humans at this time,” the release reads.
