Wuhan lab had 3 live bat coronaviruses: Report

The Chinese virology institute in the city where Covid-19 first emerged has three live strains of bat coronavirus on-site, but none match the new contagion wreaking chaos across the world. Scientists think Covid-19 -- which first emerged in Wuhan and has killed some 340,000 people worldwide -- originated in bats and could have been transmitted to people via another mammal.
