Covid-19 likely emerged from laboratory leak, US energy department says

The virus which drove the Covid-19 pandemic most likely emerged from a laboratory leak but not as part of a weapons program, according to an updated and classified 2021 US energy department study provided to the White House and senior American lawmakers, the Wall Street Journal reported on Sunday.

Conflicting hypotheses on the origins of Covid-19 have centered either on an unidentified animal transmitting the virus to humans or its accidental leak from a Chinese research laboratory in Wuhan.

The spread of Covid-19, just one in a line of infectious coronoviruses to emerge, caught global health bodies unawares in early 2020. It has since caused close to 7 million deaths worldwide, according to the World Health Organization, and disrupted trade as well as travel.

US officials, the Journal said, also declined to expand on new intelligence or analysis that led the energy department to change its position. They also noted that the energy department and FBI arrived at the same conclusion for different reasons.

The CIA remains undecided between leak and natural transmission theories, according to the National Intelligence Council study. But while the initial 2021 report did not reach a conclusion, it did offer a consensus view that Covid-19 was not part of a Chinese biological weapons program.

Chinese officials have disputed that Covid-19 could have leaked from its labs, among them the Wuhan Institute of Virology, the Chinese Center for Disease Control and Prevention, (CDC) and the Wuhan Institute of Biological Products.
