First Case of SARS-CoV-2 Transmission from Deer to Humans, Virus Has 76 Mutations!

Suara.com – For the first time, scientists have found cases of transmission of the corona virus from deer to humans. This incident occurred in Canada, United States of America.

The scientists also identified a cluster of the SARS-CoV-2 genome that had multiple mutations in the white-tailed deer.

This report highlights the potential of deer to act as viral reservoirs in animals.

In this finding, scientists analyzed 300 samples from white-tailed ruka in western and south-eastern Ontario collected in November and December last year.

When researchers sequenced the genomes of five viral samples, they discovered a new lineage that was very different from that of SARS-CoV-2.

This deer coronavirus lineage has 76 mutations compared to the original version of the virus originally identified in Wuhan, China.

Further analysis found that the lineage is thought to have evolved in animals since late 2020.

Then, the researchers compared the viral genome in the deer with those in humans in the area. They found that a person had been infected with a coronavirus similar to SARS-CoV-2 in deer.

The person lives in Southwestern Ontario and has been in close contact with deer, leading scientists to assume the person was infected with deer.

“This is the first evidence of a spread from deer to humans,” the scientists wrote.

Apart from this person, scientists have found no other cases.

The scientists also stressed the need for surveillance of SARS-CoV-2 in deer and other animals to identify reservoirs capable of promoting transmission and evolution of the virus.
