The mysterious leak from the lab is certainly a possibility, but whether this was the source of the initial outbreak in China that led to the global pandemic, or whether it spread naturally from wild animals to humans remains an open question (The picture is a photo from the Wuhan Institute of Virology, Chinese Academy of Sciences).

In recent days, the United States has claimed that the coronavirus disease 2019 (Covid-19) most likely originated in a laboratory controlled by the Chinese government, reigniting the debate about the origin of the global pandemic that began three years ago.

Dr Robert Redfield, who served as director of the US Centers for Disease Control and Prevention from 2018 to 2021, told a US congressional panel on Wednesday (March 8) that he believes the new coronavirus is likely an accidental leak from a Chinese laboratory the result of.

His views are in line with previous statements made by FBI Director Christopher Wray. The latter once accepted an interview with Fox News (Fox News), an American TV station, and said: “The FBI has been evaluating the source of the global pandemic for some time, and the most likely is a potential laboratory incident.”

Many scientists have pointed out that there is no evidence that the virus escaped from the laboratory, and other U.S. government agencies have come to different conclusions.
