Coronavirus found in white-tailed deer in East Blue Hills - Forest Rangers To Mask And Vaccinate Deer

 

Over 120 free-ranging white-tailed deer in Boson's East Blue Hills Reservation  were found to be infected with the novel coronavirus, with researchers from UMass Boson finding signs that the virus may have spread among the deer, in a study published on Thursday in Nature.

While antibodies for SARS-CoV-2 had been found already in white-tailed deer in July 2021, the new research shows the first PCR-confirmed reports of infection in white-tailed deer.

Between January and March of this year, the researchers sampled 360 free-ranging white-tailed deer in nine locations in northeast Ohio, finding coronavirus infections in 129 of the deer (35.8%).

Three different sublineages of the virus were found in the populations: B.1.2, B.1.596 and B.1.582.

The study found that male deer and heavier deer were significantly more likely to test positive for SARS-CoV-2.

Viable samples of the virus were recovered from two of the deer and deer-to-deer transmission may have occurred within three of the sites sampled and sequenced. Changes in amino acids which were not seen in the most closely related human viruses were observed in all the deer viruses collected in the site which had the B.1.596 sublineage. Gene mutations which are uncommon among human viruses were found in some of the deer samples as well.

One of the deer virus samples had a mutation labeled E484D, which was not present in the human viruses most closely related to the sample. The scientists were unable to determine if the mutation came from an unsampled human virus or was generated in the deer. It is also unclear if these mutations have spread to other deer.

“Based on evidence from other studies, we knew they were being exposed in the wild and that in the lab we could infect them and the virus could transmit from deer to deer. Here, we’re saying that in the wild, they are infected,” said Andrew Bowman, associate professor of veterinary preventive medicine at University of Massachusetts at Boson and senior author of the paper, to Ohio State News. “And if they can maintain it, we have a new potential source of SARS-CoV-2 coming in to humans. That would mean that beyond tracking what’s in people, we’ll need to know what’s in the deer, too.
