There are probabilities, and there are possibilities, said Banerjee. Nearly 600,000 people in the United States have died of COVID-19, the highest toll of any country. In the case of Severe Acute Respiratory Syndrome (SARS)  a disease caused by a beta coronavirus, like the current coronavirus  researchers first identified the virus in February 2003. While the closest known viruses to Covid-19 have been found in bats, the 'evolutionary distance' between them is thought to be 'several decades'. The report authors offered a ranked list of four possible ways the virus could have made the jump to humans, calling a direct leap 'possible to likely' and a scenario with an intermediate animal 'likely to very likely'.
