The study, published in the peer-reviewed journal Cell on May 7, was led by the University of Edinburgh and involved researchers from 20 institutions across the US, Europe, and Asia, including China.
The team analysed 167 bat coronavirus genomes and traced the origins of the virus that causes Covid-19 to bat populations in northern Laos and southwest China’s Yunnan province, where its most recent ancestor circulated five to seven years before the pandemic emerged.
Lead author Jonathan Pekar said the study showed that the original Sars-CoV-1 was circulating in western China just a year or two before Sars emerged in the southern province of Guangdong in late 2002.
