"We're continuing to work with health experts to keep pace with the evolving nature of the pandemic and regularly update our policies as new facts and trends emerge".
In February, Facebook announced that it had expanded the list of "false claims" it would remove from its platforms to include "additional debunked" statements about COVID-19 - including that COVID is "man-made or manufactured".
After the report's release, the US along with 13 other countries including Australia, Japan and South Korea issued a joint statement voicing "concerns regarding the recent WHO-convened study in China", saying the delegation lacked access to complete original data and samples.
However, the Chinese foreign ministry denied the report claiming that no one at the Wuhan lab had fallen ill before the outbreak of the virus asserting that the United States was "hyping the lab leak theory".
In April a year ago, he said he had a "high degree of confidence" that the novel coronavirus came from a lab and claimed to have seen evidence to support his certainty.More news: Biden orders intelligence agencies to investigate origins of Covid-19
"We are not saying that a lab origin is more likely than a natural one, but only that in a situation where a very unlikely event indeed has occurred, the worst pandemic in a century, we should investigate causes that seem unlikely as well as those that, to some, seem more likely".
The Wall Street Journal was first to report the intelligence surrounding the earlier hospitalizations.
The president said he has asked the intelligence community to redouble their efforts to collect and analyze information and to report back in 90 days.
In May 2020, ABC journalist Dr Norman Swan said the theory, which was backed by then US President Donald Trump, was "so unlikely" and favoured the idea that the virus jumped to humans from an animal host in the wild.
On Thursday morning Foreign Minister Marise Payne welcomed President Biden's move to increase investigations but said: 'I do note the report saying that [the virus leaked from the lab] is contested within the U.S. intelligence community'. "Here is their current position: 'while two elements in the IC leans toward the former scenario and one leans more toward the latter - each with low or moderate confidence - the majority of elements do not believe there is sufficient information to assess one to be more likely than the other'".More news: San Jose shooting: Employees among 'multiple casualties', sheriff says
Recently, well-known journalists, notably former The New York Times writers Nicholas Wade and Donald McNeil, and prominent scientists, including several who had previously expressed doubts about the lab-leak idea, have endorsed closer scrutiny of the idea, in part because of the apparent lack of serious attention it was given by the World Health Organization mission.
But the report was widely criticized, and World Health Organization chief Tedros Adhanom Ghebreyesus also said that data had been withheld from his investigators, who were only given highly restricted access to Chinese resources. The lab-leak theory, which experts have said in the past was not likely, has come under increasing scrutiny.
The Senate passed a bill to declassify what the USA government knows about the origins of Covid-19. "I'm not going to make a statement until, you know, until we know what happens after this 90-day review", Jean-Pierre replied.
Dr. Anthony Fauci, the director of the U.S. National Institute of Allergy and Infectious Diseases, was asked whether he believed COVID-19 was a "natural occurrence" at a Senate hearing on Wednesday. "And since there's a lot of concern, a lot of speculation, and since no one absolutely knows that, I believe we do need the kind of investigation where there's open transparency and all the information available to be made available to scrutinize".More news: Blinken arrives in Israel to try to bolster Gaza ceasefire
