Scientists: revealed the “closest ancestors” of SARS-CoV-2

Scientists: the & quot; closest ancestors & quot; SARS-CoV-2

The COVID-19 coronavirus pandemic most likely originated from bats.

This is the conclusion the researchers from The Pasteur Institute and the University of Laos.

Scientists have found horseshoe bats in caves in Laos, which carry coronaviruses, similar to SARS-CoV-2.

According to researchers, bats Receptor-binding domains have been identified that are part of the spike protein that allows the virus to attach to the human ACE-2 enzyme. Scientists have named the pathogens BANAL-52, BANAL-103, and BANAL-236.

The findings support the theory that bats caused the COVID-19 pandemic.

According to Bloomberg, one of the study's authors, Mark Eloit, said that the detected coronaviruses are “ the closest ancestors of SARS-CoV-2 known today. ''

“ These viruses may have contributed to the emergence SARS-CoV-2 and, in fact, may pose a future risk of direct transmission to humans '', & ndash; he warned.
