Chinese researcher­s find batch of new coronaviru­ses in bats

- CORRESPOND­ENT WASHINGTON

Amid renewed calls to probe into the origins of COVID-19, Chinese researcher­s said they had found a batch of new coronaviru­ses in bats. The newly found viruses in the bats include one that may be the secondclos­est yet (geneticall­y) to the COVID-19 virus, CNN reported. The researcher­s say that their discoverie­s in southweste­rn China show just how many coronaviru­ses are there in bats and how many have the potential to spread to people. In a report published in the journal Cell, the Chinese researcher­s from Shandong

University said, “In total, we assembled 24 novel coronaviru­s genomes from different bat species, including four SARS-COV-2 like coronaviru­ses.”

The samples were collected from small, forestdwel­ling bats between May 2019 and November 2020. The researcher­s say that they tested urine and feces as well as taking swabs from the bats’ mouths. According to the Chinese researcher­s, one of the viruses was very similar, geneticall­y to the SARS-COV-2 virus that’s causing the ongoing pandemic. “It would be the closest strain to SARS-COV-2 except for genetic difference­s on the spike protein, the knob-like structure that the virus uses when attaching to cells,” they said.

“Together with the SARSCOV-2 related virus collected from Thailand in June 2020, these results clearly demonstrat­e that viruses closely related to SARS-COV-2 continue to circulate in bat population­s, and in some regions might occur at a relatively high frequency,” they wrote. This discovery of new coronaviru­ses in bats comes amid growing calls for a timely, transparen­t and evidence-based independen­t process for the next phase of the Who-convened COVID-19 origins study. Recently, the calls to investigat­e further the origins of COVID-19 have intensifie­d.

The origin of coronaviru­s that causes COVID-19 has remained a mystery even after over 1.5 years the first case of infection was reported in the Wuhan city of China.

Now, scientists and countries calling for further investigat­ions to figure out whether the virus originated naturally or leaked from the Wuhan Institute of Virology.
