Apr 4, 2020 · The genome of the new coronavirus shows similarities to other β-CoV found in bats. 20 SARS-CoV-2 is 96.2% identical to a bat CoV RaTG13, whereas it shares 79.5% identity to SARS-CoV. It can therefore be assumed that the virus originally came from bats and has been transmitted over time to other animal hosts and ultimately to humans.
Feb 6, 2023 · The SARS-CoV-2 virus can be mapped out similar to a family tree. All lineages have names to help scientists talk about them.
