A few days ago, the US Department of Energy said it had found the virus was most likely the result of a lab leak in Wuhan but could only reach that conclusion with "low confidence". In response to that, many scientists who have studied the virus said this week that there is no new scientific evidence pointing to a lab leak. A natural origin is still the more likely theory, said Professor David Robertson, head of viral genomics and bioinformatics at University of Glasgow. พนันบาคาร่า "There's been an accumulation of evidence (what we know about the viruses biology, the close variants circulating in bats and locations of early human cases) that firmly points to a natural origin centred on the Huanan market in Wuhan city," he said.
