First Case of COVID-19 in Mule Deer Confirmed in Utah
SALT LAKE CITY — While COVID-19 was confirmed in white-tailed deer in parts of the U.S. last year, the virus was recently confirmed in Utah mule deer for the first time after the Utah Division of Wildlife Resources submitted samples taken from deer during winter health assessments.
The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service has been collaborating on a research study to test various wildlife species for the presence of SARS-CoV-2 (COVID-19). As part of the study, DWR biologists collected nasal swab samples and blood samples from deer during the annual helicopter captures where biologists perform a health check and place GPS collars on the animals. From November to December, samples were taken from roughly 280 deer statewide and were sent to two USDA labs in other states for testing.
On March 22, the APHIS’ National Veterinary Services Lab in Ames, Iowa confirmed a case of the SARS-CoV-2 delta variant in one of the samples submitted from a female mule deer in Morgan County. Only one deer tested positive for the virus from the nasal samples, but several other Utah deer had the antibodies in their blood samples, indicating the virus had been in the deer population prior to the capture.
