Scientists exploring the origins of Covid-19 are warning that time may be running out. The truth is we may never know for sure where the pandemic came from. Via WIREDUK
In 1977, an outbreak of H1N1 influenza began in the Soviet Union. It spread rapidly through schools and military camps, particularly afflicting those under 25, before becoming a global pandemic which lasted two years, reaching the UK, and eventually the US. In total, it is thought to have killed around 700,000 people around the globe.
Over the past year, Wertheim’s work on the Russian flu has been the subject of renewed interest. While the initial scientific consensus was that the Covid-19 pandemic had a natural origin, speculation has grown over the past year regarding whether the Sars-CoV-2 virus could possibly have escaped from the Wuhan Institute of Virology, a lab which was studying nine of its closest viral relatives at the time.
Chan’s own scientific detective work has provided increasing traction to the theory that Covid-19 might have had a non-natural origin. In May 2020, she published, based on early genetic sequences of people infected with the virus. It claimed that SARS-CoV-2 was unusually well placed to invade the human body when it first came to attention in December 2019.
For scientists to be really convinced that the pandemic was started by a lab leak, Wertheim says there would need to be concrete evidence that the Wuhan lab had been holding a virus which matched the genetic sequence of Sars-CoV-2 partially or in full, or epidemiological data connecting some of the earliest transmission clusters to the institute.
