Covid had natural origins, no lab leak detected

Sydney – An international team of scientists, which includes Australian Nobel laureate Professor Peter Doherty, also has scientists from the UK, the US, China, Canada, New Zealand, in a new study has claimed that evidence points to the natural origin of Covid, debunking the theory that Covid-19 leaked out of a Chinese laboratory. The scientists refuted the lab leak theory citing there is no evidence. They said: “Aside from the 1977 A/H1N1 influenza pandemic that likely originated from a large-scale vaccine challenge trial, there are no documented examples of human epidemics or pandemics resulting from research activity. No previous epidemic has been caused by the escape of a novel virus and there is no data to suggest that the Wuhan Institute of Virology (WIV) — or any other laboratory — were working on SARS-CoV-2, or any virus close enough to be the progenitor, prior to the Covid-19 pandemic. Viral genomic sequencing cell culture, which was routinely performed at the WIV, represents a negligible risk as viruses are inactivated during RNA extraction and no case of laboratory escape has been documented following the sequencing of viral samples. It displays clear similarities to SARS-CoV that spilled over into humans in Foshan, Guangdong province, China in November 2002, and again in Guangzhou, in 2003.” Both the events were linked with markets selling live animals and involved species, particularly civets and raccoon dogs, that were also sold live in Wuhan markets in 2019 and are known to be susceptible to SARS-CoV-2 infection.
