That suggests SARS-CoV-2 was being transmitted extensively around the world from early on in the epidemic, he said. But, publishing their analysis in the journal Virus Evolution, the Glasgow team said only one type of the virus was circulating. The World Health Organization said the French case was “not surprising” and urged countries to investigate any other early suspicious cases. Balloux’s team screened the genomes of more than 7,500 viruses from infected patients around the world. Their results add to a growing body of evidence that SARS-CoV-2 viruses share a common ancestor from late 2019, suggesting this was when the virus jumped from a previous animal host into people.
