The Wuhan Institute of Virology, which is at the heart of the lab-leak theory—which holds that Covid-19 was produced in a Chinese lab and unintentionally spilled to the public—conducted the study.
According to the most recent research, the Covid-19 pandemic is thought to have been caused by a zoonotic spillover since bats are thought to be coronavirus reservoirs and contain the largest concentration of coronaviruses.
However, there is a low level of confidence within the US intelligence community that Covid leaked from the WIV.
The current research claims that while there is proof of animal-to-human transmission for both SARS and MERS, the “intermediate hosts for SARS-CoV-2 remain unclear.”
