The researchers’ findings supported the theory that “Omicron may have evolved into a non-human animal species”

The Omicron study, published in the Journal of Biosafety and Biosecurity, found that “coronavirus slowly accumulated mutations over time in mice” before the virus is then “transmitted to humans by reverse zoonosis.”

The research, led by Dr Xu Jianguo, who works for China’s National Institute for Communicable Disease Control and Prevention, identified the mice as the “Most likely intermediate host.” The researchers established that the “mutation profile” of the stump “shows that the virus has adapted to infect mouse cells.”

While scientists established that Omicron developed from a strain that circulated in mid-2020, they searched for an explanation for the lack of an intermediate version of Omicron in humans, raising the potential that it evolved into an animal.

The discovery could “pose new challenges in the prevention and control of the epidemic”, because the risk of new strains of Covid circulating in the animal kingdom creates additional uncertainty in the fight against the virus.

Offering possible solutions to the problem of Covid strains circulating within non-human species, the researchers called for greater “the monitoring of animals, in particular rodents”, because of their proximity to humans.
