The second wave of Covid-19 is sweeping through India, and we are expecting a third wave. More than 3.5 million people on the globe have perished in the pandemic. Yet, no one knows how exactly the deadly virus, Sars-CoV-2, emerged and spread to humans.
We need to know how it happened, so as to prevent the next pandemic. But, even a year after the outbreak, no robust process has been established for examining the origin of the virus.
Until last month, the possibility that the virus escaped from a lab was treated as a conspiracy theory. Today, things have changed, and a lab origin of the virus remains a possible theory. The US president and the former director of the Centers for Disease Control, besides many renowned scientists, have called for a proper investigation of the origin.
As a scientific couple, we were intrigued by the virus and started an online expedition at the end of March 2020. The journey led us to discover the link between a copper mine and the nearest relative of the virus.
