The joint WHO-China study into the origins of COVID-19 says it is an “extremely unlikely” scenario that the virus leaked from a laboratory in Wuhan but Secretary of State Antony Blinken has “real concerns” about the research. “We’ve got real concerns about the methodology and the process that went into that report – including the fact that the government in Beijing apparently helped to write it,” Mr Blinken said. In the report, researchers offered four possible scenarios that caused the virus to infect humans. According to several media outlets that obtained a copy ahead of its release, due within hours, the most likely scenario was that the virus jumped from bats into another animal before making the leap to humans. The second most likely scenario was direct transmission from bats to humans, considered a “possible to likely” scenario Third was transmission from cold food, considered “possible”, followed by a lab leak.
