‘Overwhelming circumstantial evidence’ points to COVID-19 lab leak

The theory COVID-19 leaked from the Wuhan Institute of virology is possibly “more likely” than the current working hypothesis due to “overwhelming” circumstantial evidence, according to the WHO advisory committee’s Jamie Metzl. It comes after the World Health Organisation released its report into the origins of the deadly virus which placed zoonotic transmission to humans the most likely source of the pandemic. The report also ranked the likelihood of different hypotheses and claimed the virus most likely transferred from bats to humans via an intermediary zoonotic source, and that a direct transmission was the second most likely.
