The Omicron variant may have come from mice, a Chinese study says

The Omicron variant has modified the state of the coronavirus pandemic. Transactions have been canceled. The number of cases is increasing. And we have only just moved to January.

However, researchers have wondered where the omicron variant comes from. Chinese researchers recently published a study suggesting that a variant of omicron may have been derived from mice.

  • A study published in the Journal of Genetics and Genomics, readable on the pre-surface server bioRxiv, examined why the omicron transform is so different from other COVID-19 variants.
  • A team of researchers at the Beijing Chinese Academy of Sciences found that the variant of the omicron “closely resembled mutations associated with the evolution of the virus in mouse cells,” according to IFL Science.
  • “In addition, they say the mutations show that the virus has adapted to infect mouse cells,” IFL Science reports.

Scientists suggest that a variant of omicron may have jumped from mice to humans at some point, affecting our entire lives.

  • “Our results suggest that the ancestor of Omicron jumped from humans to mice, quickly accumulated mutations that contribute to the infection of that host, then jumped back into humans, indicating an interplay evolutionary pathway to the Omicron epidemic,” the study authors wrote.

South African researchers discovered a variation of the omicron on Thanksgiving weekend and sounded the alarm of a rising new variant. However, it is unclear where the variant originally came from.

According to BBC News, some South African scientists have a “highly plausible hypothesis” that a variant of omicron was from an immunocompromised patient who had been infected with COVID-19.

  • “Usually, your immune system kicks out the virus pretty quickly if it were fully operational,” Linda-Gayle Bekker, a professor who runs the Desmond Tutu HIV Foundation in Cape Town, South Africa, told BBC News.
  • “In someone where immunity is suppressed, we see the virus going on. And it just doesn’t sit, it repeats. And when it replicates, it goes through possible mutations. And somewhere where the resistance is suppressed, the virus may be able to continue for several months – if the mutation continues.” , he added.
