The COVID-19 lab leak theory, or lab leak hypothesis, is the idea that SARS-CoV-2, the virus that caused the COVID-19 pandemic, came from a laboratory. This claim is highly controversial; most scientists believe the virus spilled into human populations through natural zoonosis (transfer directly from an infected non-human animal), similar to ...
On 28 February 2023, the head of the Federal Bureau of Investigation Christopher Wray said the FBI believes Covid-19 most likely originated in the lab. [108] On 20 March 2023, the COVID-19 Origin Act of 2023 was signed into law. On June 23, 2023, the Biden administration released its report, as required by the Act. [109]
From the early outbreak of the COVID-19 pandemic, rumors and speculation arose about the possible lab origins of SARS-CoV-2, the causative agent of the COVID-19 disease.. Different versions of the lab origin hypothesis present different scenarios in which a bat-borne progenitor of SARS-CoV-2 may have spilled over to humans, including a laboratory-acquired infection of a natural or engineered vir
Maybe those experiments created COVID-19, and maybe they didn't. In any case, it's clearly not a conspiracy theory; good of Fauci to recognize the obvious, however belatedly it might be.
In the sciences, denialism is the rejection of basic facts and concepts that are undisputed, well-supported parts of the scientific consensus on a subject, in favor of ideas that are radical, controversial, or fabricated. [ 3] The terms Holocaust denial and AIDS denialism describe the denial of the facts and the reality of the subject matters ...
Shi Zhengli denied that there was a connection between the WIV and the emergence of COVID-19. [48] In February 2021, after investigations in Wuhan, the WHO team said a laboratory leak origin for COVID-19 was "extremely unlikely", [49] [50] confirming what experts expected about the likely origins and early transmission. [51]
The Lancet letter (also referred to as Calisher et al. 2020) was a statement made in support of scientists and medical professionals in China fighting the outbreak of COVID-19, and condemning theories suggesting that the virus does not have a natural origin, which it referred to as "conspiracy theories". [1] [2] The letter was published in The ...
COVID-19 pandemic. SARS-CoV-2, the causative agent of COVID-19, was first introduced to humans through zoonosis (transmission of a pathogen to a human from an animal), and a zoonotic spillover event is the origin of COVID-19 that is considered most plausible by the scientific community. [a] Human coronaviruses including SARS-CoV-2 are zoonotic ...
