From it being no worse than the flu to the vaccine conspiracy theories, Tanya Lewis has rounded up the most insidious false claims about the pandemic

This article first appeared in the Scientific American.


Because the pathogen first emerged in Wuhan, China, President Donald Trump and others have claimed, without evidence, that it started in a lab there, and some conspiracy theorists believe it was engineered as a bioweapon.

Why It’s False: U.S. intelligence agencies have categorically denied the possibility that the virus was engineered in a lab, stating that “the Intelligence Community … concurs with the wide scientific consensus that the COVID-19 virus was not man-made or genetically modified.” Chinese virologist Shi Zhengli—who studies bat coronaviruses and whose lab Trump and others have suggested was the source of COVID-19—compared the pathogen’s sequence with those of other coronaviruses her team had sampled from bat caves and found that it did not match any of them. In response to calls for an independent, international investigation into how the virus originated, China has invited researchers from the World Health Organization to discuss the scope of such a mission.

Why People Believe It: People want a scapegoat for the immense suffering and economic fallout caused by COVID-19, and China—a foreign country and a competitor of the U.S.—is an easy target. Accidental lab releases of pathogens do sometimes occur, and although many scientists say this possibility is unlikely, it provides just enough legitimacy to support a narrative in which China intentionally engineered the virus to unleash it on the world.


Since the beginning of the pandemic, Trump has lied about the disease’s severity, saying it is no more dangerous than seasonal influenzaTrump himself admitted to journalist and author Bob Woodward in recorded interviews in early February and late March that he knew COVID-19 was more deadly than the flu and that he wanted to play down its severity.

Why It’s False: The precise infection fatality rate of COVID-19 is hard to measure, but epidemiologists suspect that it is far higher than that of the flu—somewhere between 0.5 and 1 percent, compared with 0.1 percent for influenza. The Centers for Disease Control and Prevention estimates that the latter causes roughly 12,000 to 61,000 deaths per year in the U.S. In contrast, COVID-19 had caused 200,000 deaths in the country as of mid-September. Many people also have partial immunity to the flu because of vaccination or prior infection, whereas most of the world has not yet encountered COVID-19. So no, coronavirus is not “just the flu.”

Why People Believe It: Their leaders keep saying it. In addition to his repeated false claims that COVID-19 is no worse than the flu, Trump has also said—falsely—that the numbers of deaths from COVID-19 are exaggerated. In fact, reported deaths from COVID-19 are likely an undercount.


Despite a strong consensus among public health authorities that masks limit transmission of coronavirus, many people (the president included) have refused to wear one. Georgia’s governor Brian Kemp went so far as to sign an executive order banning city governments from implementing mask mandates. He even sued Atlanta’s mayor Keisha Lance Bottoms when she instituted one, although he has since dropped the lawsuit. Nevertheless, as coronavirus cases spiked around the U.S. during the summer, even states that were once staunch holdouts implemented mask orders.

Why It’s False: Masks have long been known to be an effective means of what epidemiologists call source control (preventing a sick patient from spreading a disease to others). A recent analysis published in the Lancet looked at more than 170 studies and found that face masks can prevent COVID-19 infection. It has also been widely established that people can be infected with and spread COVID-19 without ever developing symptoms, which is why everyone should wear a mask to prevent asymptomatic people from spreading the virus.

Why People Believe It: Early guidance on masks from the CDC and the WHO was confusing and inconsistent, suggesting that members of the general public did not need to wear masks unless they had symptoms of an infection. The guidance was in part driven by a shortage of high-quality surgical and N95 masks, which the agencies said should be reserved for health care workers. Even though face coverings are now mandated or recommended in many states, some people refuse to wear one because they consider it emasculating or a violation of their civil liberties.


In a book and in the conspiracy theory film Plandemic, Judy Mikovits, who once published a high-profile but eventually retracted study on chronic fatigue syndrome, makes the unsubstantiated claim that National Institute of Allergy and Infectious Diseases director Anthony Fauci and Microsoft co-founder Bill Gates could be using their power to profit from a COVID-19 vaccine. She also asserts without evidence that the virus came from a lab and that wearing masks “activates your own virus.” An excerpt from the film was widely shared by anti-vaxxers and the conspiracy theory group QAnon. The video was viewed more than eight million times on YouTube, Facebook, Twitter and Instagram before it was taken down.

Why It’s False: There is no evidence that Fauci or Gates has benefited from the pandemic or profited from a vaccine. In fact, Fauci has sounded alarms throughout the pandemic about the risks of the virus, and Gates has a long history of philanthropy geared toward eliminating communicable diseases. Mikovits’s claims about the virus’s origin and the efficacy of masks also have no scientific support.

Why People Believe It: Wealthy or influential figures such as Gates and Fauci are often the target of conspiracy theories. Trump has at times attacked Fauci, a member of his own coronavirus task force, calling him an “alarmist.” Some of the president’s followers may find it more palatable to believe that Fauci is exaggerating the severity of the outbreak than to acknowledge the Trump administration’s failure to contain it.


When a small study in France suggested the malaria drug hydroxychloroquine might be effective at treating the disease, Trump and others seized on it. The study is now widely criticized, but some people have continued to tout the medication despite growing evidence that it does not benefit COVID-19 patients. In a tweet, Trump called the hydroxychloroquine treatment “one of the biggest game changers in the history of medicine,” and he has mentioned it repeatedly in his public coronavirus briefings, continuing to hype the drug. In late July he retweeted a video featuring Stella Immanuel, a Houston, Tex.–based physician (who has made questionable assertions in the past, including that doctors had used alien DNA in treatments and that demons cause certain medical conditions by having sex with people in their dreams), claiming that hydroxychloroquine is an effective treatment for COVID-19. The video was viewed tens of millions of times before social media companies took it down.

Why It’s False: Several studies have shown that hydroxychloroquine does not protect against COVID-19 in those who are exposed. The Food and Drug Administration initially issued an emergency use authorization for the drug, but the agency later warned against its use because of the risk of heart problems and ultimately revoked its authorization. And in June the National Institutes of Health halted its clinical trial of the medication, stating that although it was not harmful to patients, it did not provide any benefit.

Why People Believe It: Initial reports suggested hydroxychloroquine might be a potentially promising drug, and people are most likely to believe the first things they learn about a topic, a phenomenon called anchoring bias. And because Trump has repeatedly claimed that the drug is effective, his supporters may be more likely to believe reports that confirm their views rather than those that challenge them.

All the myths are damaging but I would say the most damaging is probably number 7 and the whole herd immunity thing. We have never developed herd immunity to any of the commonly circulating Human corona virus types and we all get the same ones every year. There is every realistic likelihood that SARS-Cov-2 will interact with the human immune system in the same way as every other human Coronavirus. If you follow this through and consider it as a risk manager would this is the most troubling problem to consider and manage. We always planned for a flu pandemic… Read more »


Jonathan – Fascinating post. I agree with your overall approach but would add a couple of other things… 4) Test, trace isolate as a strategic competence. The test bit is tricky because we don’t know what the next pandemic will be so can’t develop tests until we know what we need to test for but we can’t have this contact tracing farce again. Work out ahead of time how to do it better next time (computer systems already in place, decide what is national and what is local, etc). Maybe we need to run it like the military and maintain… Read more »


Yes very much agree on the who test, track and trace. To be honest the art contact tracing is not really hard but to do it well you need a core of competent public health professionals who can burn shoe leather and talk to people as part of a well integrated healthcare system… All this bizarre stuff the government has been playing around with is trying to hide the basic fact that this county does not have a public health system capable of the job any more…..We then employed someone whose experience is in selling mobile phones to plug the… Read more »


Thank you for this.


Missed out the myth that the BLAME community are more prone to it. Ive been following this from day one and a little unknown source of information is the weekly NHS C19 website which lists the death rate from C19. It exemplifies the British penchant for attention to detail and categorises the facts by age, gender, ethnicity and by condition and what do I find, that the BLAME community are less prone to becoming brown bread than white people. Gravitate to Data and the weekly link

Why is this article an attack on Trump?


Because it’s an older article that’s been copied wholesale from Scientific American.

It would have been better if UK Defence Journal had written an article debunking the conspiracy myths that are currently circulating in the U.K. – predominantly around the vaccine.

George Allison

It hasn’t been copied, it’s been sent to us to also publish. That’s normal.

John Clark

Very interesting conversation George, thanks for posting and many thanks to Jonathan for his in depth breakdown.

His response lays out a clear path for the future, better than any official release U have read in fact!
