Recently, American researchers found a mutant strain of Omicron in New York white-tailed deer.
Researchers are concerned that the species could be a host for a new strain of the new coronavirus.
The United States is home to as many as 30 million white-tailed deer.
This is the first time researchers have detected a mutant strain of Omicron in a wild animal, which is now circulating in the United States and has led to a surge in confirmed cases.
