The COVID-19 pandemic was not directly linked to an incident at China's Wuhan Institute of Virology, according to a paper that was disclosed by US intelligence services.

However, it was noted in the four-page report by the Office of the Director of National Intelligence (ODNI) that the US intelligence community was still unable to completely rule out the idea that the virus originated in a lab and had been unable to identify the pandemic's origins.

“The Central Intelligence Agency and another agency remain unable to determine the precise origin of the COVID-19 pandemic, as both (natural and lab) hypotheses rely on significant assumptions or face challenges with conflicting reporting,” the ODNI report said.

The report said that while “extensive work” had been conducted on coronaviruses at the Wuhan institute (WIV), the agencies had not found evidence of a specific incident that could have caused the outbreak.

“We continue to have no indication that the WIV’s pre-pandemic research holdings included SARSCoV-2 or a close progenitor, nor any direct evidence that a specific research-related incident occurred involving WIV personnel before the pandemic that could have caused the COVID pandemic,” the report said.

The origins of the coronavirus pandemic have been a matter of furious debate in the United States almost since the first human cases were reported in Wuhan in late 2019.
