COVID-19 misinformation
, including disinformation and conspiracy theories about the scale of the COVID-19 pandemic and the origin, prevention, diagnosis, and treatment of the disease has been spread through social media, text messaging, and mass media. False information has been propagated by celebrities, politicians, and other prominent public figures. Many countries have passed laws against "fake news", and thousands of people have been arrested for spreading COVID-19 misinformation. The spread of COVID-19 misinformation by governments has also been significant.
Commercial scams have claimed to offer at-home tests, supposed preventives, and "miracle" cures. Several religious groups have claimed their faith will protect them from the virus. Without evidence, some people have claimed the virus is a bioweapon accidentally or deliberately leaked from a laboratory, a population control scheme, the result of a spy operation, or the side effect of 5G upgrades to cellular networks.
The World Health Organization declared an "infodemic" of incorrect information about the virus that poses risks to global health. While belief in conspiracy theories is not a new phenomenon, in the context of the COVID-19 pandemic, this can lead to adverse health effects. Cognitive biases, such as jumping to conclusions and confirmation bias, may be linked to the occurrence of conspiracy beliefs. Uncertainty among experts, when combined with a lack of understanding of the scientific process by laypeople, has likewise been a factor amplifying conspiracy theories about the COVID-19 pandemic. In addition to health effects, harms resulting from the spread of misinformation and endorsement of conspiracy theories include increasing distrust of news organizations and medical authorities as well as divisiveness and political fragmentation.
Overview
In January 2020, the BBC reported on the developing issue of conspiracy theories and bad health advice regarding COVID-19. Examples at the time included false health advice shared on social media and private chats, as well as conspiracy theories such as the outbreak being planned with the participation of the Pirbright Institute. In January, The Guardian listed seven instances of misinformation, adding the conspiracy theories about bioweapons and the link to 5G technology, and including varied false health advice.In an attempt to speed up research sharing, many researchers have turned to preprint servers such as arXiv, bioRxiv, medRxiv, and SSRN. Papers are uploaded to these servers without peer review or any other editorial process that ensures research quality. Some of these papers have contributed to the spread of conspiracy theories. Preprints about COVID-19 have been extensively shared online and some data suggest that they have been used by the media almost 10 times more than preprints on other topics.
According to a study published by the Reuters Institute for the Study of Journalism, most misinformation related to COVID-19 involves "various forms of reconfiguration, where existing and often true information is spun, twisted, recontextualised, or reworked"; less misinformation "was completely fabricated". The study also found that "top-down misinformation from politicians, celebrities, and other prominent public figures", while accounting for a minority of the samples, captured a majority of the social media engagement. According to their classification, the largest category of misinformation was "misleading or false claims about the actions or policies of public authorities, including government and international bodies like the WHO or the UN".
In addition to social media, television and radio have been perceived as sources of misinformation. In the early stages of the COVID-19 pandemic in the United States, Fox News adopted an editorial line that the emergency response to the pandemic was politically motivated or otherwise unwarranted, and presenter Sean Hannity claimed on-air that the pandemic was a "hoax". When evaluated by media analysts, the effect of broadcast misinformation has been found to influence health outcomes in the population. In a natural experiment, two similar television news programs that were shown on the Fox News network in February–March 2020 were compared. One program reported the effects of COVID-19 more seriously, while a second program downplayed the threat of COVID-19. The study found that audiences who were exposed to the news downplaying the threat were statistically more susceptible to increased COVID-19 infection rates and death. In August 2021, television broadcaster Sky News Australia was criticised for posting videos on YouTube containing misleading medical claims about COVID-19. Conservative talk radio in the US has also been perceived as a source of inaccurate or misleading commentary on COVID-19. In August and September 2021, several radio hosts who had discouraged COVID-19 vaccination, or expressed skepticism toward the COVID-19 vaccine, subsequently died from COVID-19 complications, among them Dick Farrel, Phil Valentine and Bob Enyart.
Misinformation on the subject of COVID-19 has been used by politicians, interest groups, and state actors in many countries for political purposes: to avoid responsibility, scapegoat other countries, and avoid criticism of their earlier decisions. Sometimes there is a financial motive as well. Multiple countries have been accused of spreading disinformation with state-backed operations in the social media in other countries to generate panic, sow distrust, and undermine democratic debate in other countries, or to promote their models of government.
A Cornell University study of 38 million articles in English-language media around the world found that US President Donald Trump was the single largest driver of the misinformation. Analysis published by National Public Radio in December 2021 found that as American counties showed higher vote shares for Trump in 2020, COVID-19 vaccination rates significantly decreased and death rates significantly increased. NPR attributed the findings to misinformation.
Virus origin
The consensus among virologists is that the most likely origin of the SARS-CoV-2 virus to be natural crossover from animals, having spilled-over into the human population from bats, possibly through an intermediate animal host, although the exact transmission pathway has not been determined. Genomic evidence suggests an ancestor virus of SARS-CoV-2 originated in horseshoe bats.An alternative hypothesis under investigation, deemed unlikely by the majority of virologists given a lack of evidence, is that the virus may have accidentally escaped from the Wuhan Institute of Virology in the course of standard research. A poll in July 2021 found that 52% of US adults believe COVID-19 escaped from a lab.
Unsubstantiated speculation and conspiracy theories related to this topic have gained popularity during the pandemic. Common conspiracy theories state that the virus was intentionally engineered, either as a bio-weapon or to profit from the sale of vaccines. According to the World Health Organization, genetic manipulation has been ruled out by genomic analysis. Many other origin stories have also been told, ranging from claims of secret plots by political opponents to a conspiracy theory about mobile phones. In March 2020, the Pew Research Center found that a third of Americans believed COVID-19 had been created in a lab, and a quarter thought it had been engineered intentionally. The spread of these conspiracy theories is magnified through mutual distrust and animosity, as well as nationalism and the use of propaganda campaigns for political purposes.
The promotion of misinformation has been used by American far-right groups such as QAnon, by rightwing outlets such as Fox News, by US President Donald Trump and also other prominent Republicans to stoke anti-China sentiments, and has led to increased anti-Asian activity on social media and in the real world. This has also resulted in the bullying of scientists and public health officials, both online and in-person, fueled by a highly political and oftentimes toxic debate on many issues. Such spread of misinformation and conspiracy theories has the potential to negatively affect public health and diminish trust in governments and medical professionals.
The resurgence of the lab leak and other theories was fueled in part by the publication, in May 2021, of early emails between National Institute of Allergy and Infectious Diseases director Anthony Fauci and scientists discussing the issue. Per the emails in question, Kristian Andersen had heavily considered the possibility, and emailed Fauci proposing possible mechanisms, before ruling out deliberate manipulation with deeper technical analysis. These emails were later misconstrued and used by critics to claim a conspiracy was occurring. The ensuing controversy became known as the "Proximal Origin". However, despite claims to the contrary in some US newspapers, no new evidence has surfaced to support any theory of a laboratory accident, and the majority of peer-reviewed research points to a natural origin. This parallels previous outbreaks of novel diseases, such as HIV, SARS and H1N1, which have also been the subject of allegations of laboratory origin.
Wuhan lab origin
Bio-weapon
One early source of the bio-weapon origin theory was former Israeli secret service officer Dany Shoham, who gave an interview to The Washington Times about the biosafety level 4 laboratory at the Wuhan Institute of Virology. A scientist from Hong Kong, Li-Meng Yan, fled China and released a preprint stating the virus was modified in a lab rather than having a natural evolution. In an ad hoc peer-review, her claims were labelled as misleading, unscientific, and an unethical promotion of "essentially conspiracy theories that are not founded in fact". Yan's paper was funded by the Rule of Law Society and the Rule of Law Foundation, two non-profits linked to Steve Bannon, a former Trump strategist, and Guo Wengui, an expatriate Chinese billionaire. This misinformation was further seized on by the American far-right, who have been known to promote distrust of China. In effect, this formed "a fast-growing echo chamber for misinformation". The idea of SARS-CoV-2 as a lab-engineered weapon is an element of the Plandemic conspiracy theory, which proposes that it was deliberately released by China.The Epoch Times, an anti-Chinese Communist Party newspaper affiliated with Falun Gong, has spread misinformation related to the COVID-19 pandemic in print and via social media including Facebook and YouTube. It has promoted anti-CCP rhetoric and conspiracy theories around the coronavirus outbreak, for example through an 8-page special edition called "How the Chinese Communist Party Endangered the World", which was distributed unsolicited in April 2020 to mail customers in areas of the United States, Canada, and Australia. In the newspaper, the SARS-CoV-2 virus is known as the "Chinese Communist Party| virus", and a commentary in the newspaper posed the question, "is the novel coronavirus outbreak in Wuhan an accident occasioned by weaponizing the virus at that lab?" The paper's editorial board suggested that COVID-19 patients cure themselves by "condemning the " and "maybe a miracle will happen".
In response to the propagation of theories in the US of a Wuhan lab origin, the Chinese government promulgated the conspiracy theory that the virus was developed by the United States army at Fort Detrick. The conspiracy theory was also promoted by British MP Andrew Bridgen in March 2023.
In 2025, the official White House website under the Donald Trump administration claimed that the COVID-19 virus emerged as a result of a leak in a Chinese laboratory.
