Three years after the start of the pandemic, gray areas persist, particularly around the origins of Covid-19. Determined to shed light on this virus, which appeared in China, the President of the United States, Joe Biden, announced on Tuesday March 21 that he had enacted a transparency law on the origins of this pandemic. This makes it possible to declassify all documents relating to this subject.

“We need to get to the bottom of the origins of the Covid-19 pandemic to ensure we can better prevent future pandemics,” Joe Biden said. “My administration will declassify and release as much information as possible,” while respecting “national security,” the president pledged.

Supported initially by the Republican opposition, this text was finally the subject of a massive consensus with the Democrats, since it was voted unanimously by the House of Representatives – with a conservative majority. This is all the more notable since the pandemic has created particularly deep partisan divisions in the United States, whether on vaccination for example or preventive measures.

Federal Police Director Christopher Wray recently said a lab accident in Wuhan, China was “very likely” to be the cause of the Covid-19 pandemic, soon after a similar hypothesis put forward by the US Department of Energy. This has led the World Health Organization in particular to ask Americans to share their information.

The scientific community remains divided between supporters of the hypothesis of transmission by intermediate animal and those who defend the thesis of the escape from a laboratory in Wuhan.
