White-tailed deer on Staten Island have been found carrying the highly transmissible Omicron variant of the coronavirus, marking the first time the variant has been reported in wild animals.

The findings add to a growing body of evidence that white-tailed deer are easily infected by the virus. The results are likely to intensify concerns that deer, which are widely distributed across the United States and live near humans, could become a reservoir for the virus and a potential source of new variants.
