The conspiracy theories about the origins of the coronavirus, debunked

Rumor is the coronavirus started in a Chinese lab. 

Here’s how we know it didn’t.

The signs that the small, scattered coronavirus outbreak in the United States could spiral into a larger-scale problem are growing. A new analysis, first reported by STAT, found there are likely now 500 to 600 (mostly undetected) cases of Covid-19, the disease caused by the coronavirus, in Washington state alone. “January 1 in Wuhan was March 1 in Seattle,” computational biologist Trevor Bedford, who did the analysis, told STAT, referring to the Chinese city where the virus emerged and began rapidly infecting humans.

The decisions federal and local public health officials make this week — to test more people with symptoms, inform the public about the risk, isolate the sick, and institute other measures — will be crucial. So will the speed at which they execute them.

This could be a make-or-break moment where US cases remain relatively low and dispersed, or explode in the coming weeks, like they did in Wuhan in January.

Meanwhile, on Fox News and social media, a dangerous conspiracy theory about the origin of the health crisis won’t die.

There are two main versions of the rumor, and they have one common thread: that the coronavirus, SARS-CoV-2, originated in a level 4 (the highest biosafety level) research laboratory in Wuhan.

In one version of the rumor, the virus was engineered in the lab by humans as a bioweapon. In another version, the virus was being studied in the lab (after being isolated from animals) and then “escaped” or “leaked” because of poor safety protocol.

The Wuhan Institute of Virology is a real place, and the exact origin of the novel coronavirus is still a mystery, with researchers racing since the outbreak began to figure it out. But already, virologists who’ve parsed the genome and infectious disease experts who study coronaviruses have more than enough evidence to show that the virus is brand new and came from nature, not the Wuhan lab. A large group of them, citing genome analyses from multiple countries, recently affirmed in The Lancet that the virus originated in wildlife.

The emergence of the virus in the same city as China’s only level 4 biosafety lab, it turns out, is pure coincidence.

Conspiratorial claims about the Wuhan lab are circulating on cable news and social media

Before we get to debunking, let’s note who is spreading rumors about the origins of the virus.

First, several prominent US conservative pundits and politicians — known to regularly spew nonsense (and bash China) — have been politicizing the bioweapon rumor for weeks.

“It probably is a ChiCom laboratory experiment that is in the process of being weaponized,” right-wing radio host and Presidential Medal of Freedom recipient Rush Limbaugh said of the virus on February 24. “All superpower nations weaponize bioweapons.”

Sen. Tom Cotton (R-AR) has repeatedly suggested before Congress and on Fox News that the virus could have come from the lab.

On Monday, former White House strategist Steve Bannon went on Fox News to defend Cotton and imply that the Chinese Communist Party was still hiding something about the origin of Covid-19. “The mainstream media and far left [are] saying, ‘Oh, he’s a conspiracy theorist,”’ Bannon said. ”All he’s saying: It’s incumbent upon the Chinese Communist Party and President Xi [Jinping] to come out and give all information ... this is all Cotton’s saying.”

In the New York Post, Steven Mosher, a regular critic of China’s population control measures, has stoked the leakage rumor, using an array of circumstantial clues that Chinese labs’ handling of deadly pathogens can’t be trusted.

Similar rumors have also been running rampant in online forums in China. The South China Morning Post on February 20 debunked yet another rumor of the virus escaping from the lab in China:

More rumours swirled online over the weekend, this time that [Wuhan Institute of Virology] researcher Chen Quanjiao had reported the head of the institute, Wang Yanyi, claiming she had “sold experimental animals” to the live animal and seafood market and “leaked the virus” from the lab.

But Chen denied the claim, saying she was angry that her name had been used to fabricate information. “The recent rumours about the institute have affected the researchers as they try to tackle key problems,” Chen said in a statement.

The scientific evidence disproving these rumors matters because the conspiracy theory could persist and undermine trust in public health authorities at this critical moment. As the Washington Post reported Sunday, the rumor that the virus came from a Chinese lab is one reason residents of one Alabama county are currently unnerved and distrustful of the response to Covid-19 in their state.

“Conspiracy theories about manmade viruses are not new. We saw this with HIV — the rumor that the US made it and introduced it into Africa. But they are really dangerous kinds of things to get spread around,” Gerald Keusch, a professor of medicine and international health and associate director of Boston University’s National Emerging Infectious Diseases Laboratories, told Vox.

So let’s walk through what we know about the virus, and why it’s time to put the lab rumor to rest.

The virus originated in bats and then jumped to humans, perhaps through other animals

Soon after the Chinese government acknowledged there was an outbreak of a mysterious new virus in late December in Wuhan, scientists raced to sequence its genome. By mid-January, they had it and shared it with the World Health Organization.

Soon after that, scientists saw that the virus closely resembled viruses that circulate in bats. “If you look at the genetic sequence of the virus, it’s closely related to a bat virus, about 96 percent the same,” Jim LeDuc, head of the Galveston National Laboratory, a level 4 biosafety lab in Texas, told Vox. “There’s been talk about a pangolin intermediate host; that’s probably not true.”

Chinese officials also reported that several of the first cluster of cases had ties to a live animal market where both seafood and other wildlife were sold as food. (The market has since been closed.) The market soon became the leading hypothesis for how the virus made the leap into humans, where it’s been able to spread efficiently ever since.

A simple guide to the vaccines and drugs that could fight coronavirus

The genetic evidence and epidemiological information, according to three esteemed infectious disease researchers writing in the New England Journal of Medicine, “implicates a bat-origin virus infecting unidentified animal species sold in China’s live-animal markets.”

According to a genome analysis by Tanja Stadler from the Department of Biosystems Science and Engineering at ETH Zurich in Basel, the virus first began transmitting in humans in China as early as the first half of November 2019.

“The widespread hypothesis that the first person was infected at an animal market in November is still plausible,” Stadler said in a statement. “Our data effectively rule out the scenario that the virus circulated in humans for a long time before that.”

LeDuc agrees with the hypothesis that the animal market played a role in the virus jumping to humans. “The linkage back to the market is pretty realistic, and consistent with what we saw with SARS,” said LeDuc. “It’s a perfectly plausible and logical explanation: The virus exists in nature and, jumping hosts, finds that it like humans just fine, thank you.“

Unfortunately, there’s a long history of these “spillover” events, where an emerging disease jumps from wildlife to humans, turning into a pandemic. And scientists say we should expect them with more travel, trade, connectivity, urbanization, climate change, and ecological destruction, if we don’t stop the drivers.

What researchers have to figure out now is how exactly the coronavirus jumped to humans: perhaps through a human eating an infected animal, or through humans being exposed to infected feces or urine. “All we know [is] its likely distant source was bats, but we don’t know who was between bats and people,” said Vincent Racaniello, a professor of microbiology and immunology at Columbia and host of the This Week in Virology podcast. “It could be a direct infection [between bats and humans] as well.”

A preliminary scientific paper shows this is a genuinely new virus, and there’s no way it could have been engineered by humans

In a recent podcast episode, Racaniello discussed with two other researchers a fascinating preprint paper (that’s currently under peer review, according to the authors) about the virus origin. The key finding: that SARS-CoV-2 is “not a laboratory construct nor a purposefully manipulated virus.”

The paper, which was uploaded onto Virological.org in February, is written by several leading microbiologists who closely examined the SARS-CoV-2 genome.

Specifically, they found the unusual biochemical features of the virus could only have come about two ways after the virus jumped from animal to humans, or what’s called zoonotic transfer. The ways, they write, are: “1) natural selection in a non-human animal host prior to zoonotic transfer, and 2) natural selection in humans following zoonotic transfer.”

In other words, nature came up with these weird characteristics in the genome, either in an intermediary animal between bats and people or in humans after the virus infected one. As Racaniello put it on his podcast: “Humans could never have dreamed this up.”

What’s more, he noted, no known lab anywhere in the world was working on a coronavirus like this one, and its closest relative is a bat virus found in a cave in 2013 in Yunnan, China, 1,000 miles from Wuhan.“Presumably there’s a common ancestor, most likely from a bat or an intermediary animal that was contaminated by that bat,” Racaniello says.
The coronavirus would be a bad bioweapon

Several experts told me the theory that the virus was meant to be a bioweapon doesn’t make sense, either. One big reason: Covid-19 isn’t all that deadly or transmissible, compared to other potential pathogens out there.

“To make it as a bioweapon, if that’s what you wanted to do, there are scarier and more virulent pathogens to work with,” said Keusch of Boston University.

For instance, Ebola and the West African Lassa virus are deadly threats that can only be studied in biosafety level 4 labs, like Wuhan. Crimean-Congo hemorrhagic fever is a tick-borne disease that has a death rate of 30 to 50 percent. The global death rate for Covid-19, meanwhile, is around 3 percent at the moment, but it’s expected to come down dramatically as more cases are discovered in the coming weeks. And even now, it varies widely by country and region.

Simply put, if you wanted to release a bioweapon to kill a lot of people, there are much deadlier pathogens you could use.
The Wuhan lab has the same safety protocols as top biosafety labs in the US and Europe

In his article in the New York Post, Mosher suggests that we shouldn’t trust the officials who ran the Wuhan lab. “It sure sounds like China has a problem keeping dangerous pathogens in test tubes where they belong, doesn’t it?” he says.

I asked LeDuc, who runs the Galveston biocontainment lab, if he has any experience with the Wuhan lab. Turns out he has a lot. He and his colleagues have worked for six years with the Chinese team there, both in advising them on building their lab and keeping it safe, and on scientific collaboration. “I can tell you that lab in Wuhan is equivalent to any lab here in the US and Europe,” he said.

For instance, many labs now use radio waves to track and inventory vials containing dangerous pathogens.

Keusch agrees. “I don’t think there’s any likelihood that the lab is less prepared in terms of protocol and capability than any lab in the US. It’s really good, though nothing is perfect,” he said.

The rumors have also reportedly hurt the lab’s ability to do its work.

“The rumours … have caused severe damage to our researchers who have been dedicated to working on the front line, and seriously interrupted the emergency research we are doing during the epidemic,” the lab said in a statement, according to the South China Morning Post.

Why we need to figure out all the details of where the virus came from

According to Bruce Aylward, an epidemiologist who led the World Health Organization’s recent mission to China to assess its Covid-19 response, the investigation into where and how the virus jumped to people is ongoing. The focus remains on the (now closed) Huanan Wholesale Seafood Market, the wildlife market inside it, and other area markets.

“Ever since SARS, the market authorities now have to record which animals are sold by whom and where they come from in these markets. So now there’s a list of 10 vendors from seven provinces,” he told my colleague Julia Belluz in a recent interview. “Then China’s CDC can do a case control study based on where in the market these animals were.”

The focus in the past month has been on saving lives, he said, but as new cases and deaths decline, the investigators will eventually be able to turn back to getting animal info from the market vendors and testing the animals.

Racaniello says it’s critical that the source is identified to eliminate the chance that the virus is introduced into people again.

For LeDuc, China’s experience with the coronavirus should be a clear message of the great public health threat live animal markets post.

“The reason we’re seeing [coronaviruses like SARS and SARS-CoV-2 emerge] in China is they have these live animal markets, where they bring in animals alive and co-house them, one cage on top of another, where there’s an opportunity for transmission between atypical hosts,” says LeDuc.

We’ll need to be patient for Chinese investigators to get to the bottom of how the virus made the jump from animals to humans. In the meantime, remember that in a public health crisis, conspiracy theories are a distraction. Rather, it’s our collective responsibility to stay focused on keeping each other safe.

Facebook doubles down on removing coronavirus conspiracy theories

Facebook, Twitter, YouTube, and TikTok are all battling misinformation related to the novel coronavirus.

Social media companies are increasing their vigilance about removing coronavirus conspiracies. Facebook, in particular, continues to update its policies as the outbreak — and corresponding disinformation — spreads.

On Tuesday, Mark Zuckerberg reiterated in a Facebook post that the platform was removing conspiracy theories related to the coronavirus that have been flagged by global health organizations, in addition to labeling coronavirus misinformation with “fact check” labels to let users know that such content had been rated false. Zuckerberg also said that Facebook is providing the World Health Organization (WHO) “as many free ads as they need.” At the same time, Zuckerberg said the company will block ads that try to exploit the situation, such as those that claim a product has a miracle cure for the Covid-19 disease.

It’s been more than two months since a novel strain of coronavirus popped up in Wuhan, China, and proceeded to spread to countries across the world. And as that’s happened, panic has continued to disseminate throughout social media, forcing tech platforms to grapple with what the World Health Organization is calling an “infodemic.”

As of March 4, the novel coronavirus linked to Wuhan, China, has infected nearly 95,000 people, mostly in mainland China, and there are cases popping up throughout the United States. More than 3,200 people have died, though researchers at Johns Hopkins tracking the disease also report more than 51,000 recoveries from the illness.

With more and more people searching online for information about the coronavirus outbreak, they can easily encounter a barrage of misleading and potentially dangerous information. And the WHO, which has also released its own “myth-busting” resources, is warning that misinformation about the novel coronavirus has caused harmful stigmatization and discrimination. In the US, for instance, there is a growing number of reports about misinformation fueling racism against Asian Americans.

Facebook, Twitter, YouTube, and TikTok have all told Recode that they’ve been working to promote factual content and some are limiting the reach of posts with misinformation on their platforms. Twitter, for instance, has put a warning label linking to the Centers for Disease Control and Prevention (CDC) when users search “coronavirus.” Meanwhile, the WHO has now joined TikTok in an effort to boost accurate information about the illness, and several of those companies met with the public health organization at Facebook back in February.


The CDC and the WHO recommend several basic measures to help prevent the spread of respiratory diseases such as Covid-19:

DO
Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.
Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
Stay home when you are sick; contact your health care provider immediately if you think you’ve been exposed to Covid-19.

DON’T
Touch your face, particularly your eyes, nose, or mouth.
Travel if you have a fever and cough.
Wear a face mask if you are well. Face masks should be used by people who show symptoms of Covid-19 to help prevent the spread of the disease to others.

Information on the coronavirus outbreak, including its severity, may change as it spreads. Find answers to common questions here, and stay up to date with Vox’s coverage here.

Still, efforts by these social media platforms have not managed to stop the spread of misleading or outright false hoaxes about the outbreak in the form of posts and videos that have racked up thousands of clicks, “Likes,” and shares. A significant amount of false information about the coronavirus is also spreading on private channels. Take WhatsApp, for instance. As the Washington Post reported, the encrypted platform has seen a flurry of wrong information about the coronavirus, creating panic among its users throughout the world.

Another problem involves politicians promoting the idea that the coronavirus is a hoax or spreading other conspiracy theories about the virus. A Facebook spokesperson confirmed to Recode that the company would remove false claims and conspiracy theories flagged by world health organizations that have been shared by politicians or elected officials.

While we’re seeing a wide variety of false coronavirus posts across these platforms, it’s still hard to say how widespread the misinformation problem is. But it’s significant enough that well-regarded institutions, including Johns Hopkins University, research centers in England, and even NASA have had to issue statements or comments debunking claims that have been floated online. Advocacy groups such as Media Matters have also been busy tracking down false and misleading posts.

Although there is a seemingly endless stream of sources spreading misinformation about the Wuhan coronavirus around the web, we’ve identified and debunked a few of the most pervasive hoaxes.
False: The novel coronavirus sickness is caused by 5G

On social media, some are pushing the idea that the novel coronavirus was caused by or can be linked to deployment of 5G technology in Wuhan, China. There are several “strains” of this theory floating around online. One premise is that 5G technology can weaken the immune system and make the common cold more virulent. Another promotes the idea that the 5G technology itself is causing the symptoms that have been attributed to the novel coronavirus. One version of the theory pushes the idea that the technology absorbs oxygen in the lungs, which “causes coronavirus.”

That idea has been flagged false by a UK-based third-party fact-checker, called Full Fact, that works with Facebook. There’s no evidence that 5G impacts the immune system, and no proof that it has any link to the novel coronavirus.
False: There’s a plot to “exterminate” people infected with the new coronavirus

On social media, some have floated the claim that China sought permission from the country’s Supreme Court to kill people infected with the novel coronavirus. Several fact-checkers, including Snopes, have determined these reports to be false and to have originated from a website with several “red flags.”
An account with more than 30,000 followers share this false theory.

Poynter observed that some social media accounts continue to push the idea that China is planning to kill people with the illness. Meanwhile, some accounts have floated that the idea that the incineration of human bodies is causing an excess of sulfur dioxide, which they imply can be seen from satellite images. There is no evidence that any of this is true, and a research meteorologist from NASA told the UK fact-checking organization Full Fact that the images these theories are based on aren’t live satellite data.

“Although satellite data has been used in the construction of the emission inventories, these emissions do not account for the day-to-day variations in SO2 emissions and as such cannot account for sudden changes in human activity,” Arlindo M. da Silva told the fact-checking organization.
False: Scientists have proven that humans got the novel coronavirus from eating bats

One prominent theory is that the coronavirus spread through human consumption of bats. BuzzFeed reported that a prominent video about the novel coronavirus in Hindi that’s attracted more than 13 million amplified the claim that eating bats caused the coronavirus outbreak. This theory, which has popped up throughout social media, is also linked to unfounded speculation that the coronavirus was started at the Wuhan Virology Institute.

Those claims have helped fuel racism against people of Chinese descent, and Asian people more broadly, throughout the world.

YouTube

It’s true that there has been research into a potential link between bats and the coronavirus, but it’s important to be very cautious in interpreting the findings. First, there is no evidence that eating bats caused the coronavirus outbreak. And Jonathan Epstein, a veterinarian and an epidemiologist EcoHealth Alliance, told Vox earlier this month that it’s “still not known” whether this outbreak started with bats at an animal market.

“It’s clear there was some environmental contamination in the market that includes this virus. And that’s what we know so far. So it’s likely that people were infected in that market,” Epstein told Vox. “But I think there is still some question about how the earlier cases may have been exposed.”

And here’s what the CDC reports: “Analysis of the genetic tree of this virus indicates it originated in bats, but whether the virus jumped directly from bats or whether there was an intermediary animal host is not, yet, known.”
False: Scientists predicted the virus will kill 65 million people

In October 2019, a Johns Hopkins research center ran an “exercise” that aimed to model the global response to a potential epidemic. Many people online have misinterpreted the study and erroneously linked its predictions to the possible death toll of an outbreak similar to what we’re currently witnessing with the novel coronavirus. In other words, the Johns Hopkins study had nothing to do with the coronavirus, although the scenario studied might seem similar. 


This is a popular line of misinformation on Twitter. There are several tweets, including one that’s still up with over 140,000 “likes,” claiming that scientists have predicted that the Wuhan coronavirus will kill 65 million people. That’s not accurate.

“We modeled a fictional coronavirus pandemic, but we explicitly stated that it was not a prediction,” the Johns Hopkins Center for Health Security said in a statement. “We are not now predicting that the nCoV-2019 outbreak will kill 65 million people.”
False: China built a biological weapon that was leaked from a lab in Wuhan

Right now, it’s not clear where this new strain of coronavirus originated. Officials believe it may be linked to a seafood market in Wuhan, but scientists still aren’t exactly sure how or where it developed.

On social media, however, there are many other completely unproven theories about its origin that imply the outbreak of the virus may be linked to bioweapons research at the Wuhan Institute of Virology, a research institute that houses the Wuhan National Biosafety Laboratory. This Facebook post that’s been shared more than 4,000 times says that it’s “believed that the Wuhan Institute of Virology is where the disease may have originated.”
Screenshot from the “Behold Israel” account, which implies that the Wuhan-linked coronavirus may have originated at a biosafety laboratory in Wuhan.

This idea appears to be based, in part, on comments a former Israeli military officer shared with the Washington Times, a right-wing outlet whose past articles have suggested that President Barack Obama might be Muslim and have spread conspiracy theories. Back in January Jim Banks, a Republican congressman from Indiana, even tweeted out a link to the Washington Times article. His tweet has been shared more than 1,000 times. (Rep. Banks did not respond to a request for comment.) And this month, Sen. Tom Cotton also amplified similar speculations.

As shocking as the biowarfare lab theory might be, experts have told the Washington Post that there’s no evidence to support it. And the lab itself said in a statement that misinformation had “caused severe damage to our researchers who have been dedicated to working on the front line, and seriously interrupted the emergency research we are doing during the epidemic.”

False: Chinese spies smuggled the virus out of Canada

Social media posts are pushing the unproven premise that the novel coronavirus found in Wuhan was smuggled from a lab in Canada as part of China’s clandestine quest for a bioweapon, a theory debunked by Politifact. It’s a theory that seems to be somewhat related to the Wuhan lab conspiracy. One tweet by Republican Party official Solomon Yue, who has more than 100,000 followers, said: “#coronavirus is stolen from Canada by espionage & sent to Wuhan to be weaponized to kill foreign enemies.”

#coronavirus is stolen from Canada by espionage & sent to Wuhan to be weaponized to kill foreign enemies. Now the deadly weaponized virus kills 80 Chinese & no foreigners & becomes Emperor Shithole's Chernobyl! https://t.co/aOyIbvmC39— Solomon Yue (@SolomonYue) January 27, 2020

Although a Chinese researcher working in Canada is under investigation for a possible policy breach after she was invited to the Wuhan lab twice a year for two years, according to Politifact, there’s “no evidence” to support the claim that she “stole coronavirus samples and gave them to the Wuhan lab to create biological weapons.”

False: A coronavirus vaccine already exists

Another popular theory is that a vaccine for the novel coronavirus already exists, and some are even suggesting that the vaccine was previously patented. While researchers in several countries are working to develop a vaccine, no such vaccine has yet been developed, according to FactCheck.org and Politifact. But this hasn’t stopped people from going online and claiming otherwise.

A recent post on Facebook claims that the coronavirus was a “set up” to sell vaccines and includes screenshots claiming to show a patent for a new vaccine. In this particular case, because Facebook’s fact-checkers verified the post as containing false information, a handful of “related articles” show up below the post, pointing users to verified sites that debunk the vaccine conspiracy theory. If you try to share the post, Facebook issues a warning stating that independent fact-checkers have said it contains false information.

But even though Facebook has placed warnings on some vaccine hoaxes related to the Wuhan coronavirus, the content isn’t flagged as false on every platform. On Twitter, for example, one tweet that’s gained close to 2,000 “likes” suggests that a vaccine for the coronavirus is owned by the Pirbright Institute, an English infectious disease research institute that focuses on farm animals.

This claim is false. The Pirbright Institute issued a statement shared by FactCheck.org, clarifying that its researchers don’t work with human coronaviruses, and that a patent that they hold is unrelated to the current coronavirus linked to Wuhan.

Some have also attempted to profit from spreading the false information that’s there’s a cure (there’s none yet), and the Federal Trade Commission warned the public earlier this month that “scammers are taking advantage of fears” about the illness and “setting up websites to sell bogus products, and using fake emails, texts, and social media posts as a ruse to take your money and get your personal information.
False: There were 100,000 confirmed cases in January

As of March 4, there were nearly 95,000 cases of the coronavirus, but at the very end of January, when that number was less than 10,000, people were vastly inflating the number of infected people beyond what any official source has reported.

It’s an important reminder that, when trying to figure out the scale of the virus’s spread, it’s worth looking to reputable, official sources, such as the World Health Organization. The Center for Systems Science and Engineer at Johns Hopkins also maintains a useful map documenting the number of confirmed cases throughout the world.

It’s true that on January 26, one public health expert told the Guardian, however, “Almost certainly many tens of thousands of people are infected.” He added, “My best guess now is perhaps 100,000 cases right now.” But that big scary number can be misleading because it was a guess and that number had not been confirmed.
A video on YouTube that claims to portray a nurse in Wuhan, China, who is transcribed as saying that 90,000 are now infected with the new coronavirus.

Nevertheless, many popular posts on social platforms spread statistics that served to scare people with numbers that do not match the official count. Some of these posts cite medical workers in Wuhan, without evidence. For instance, one YouTube video posted on January 25 shows someone identified as a nurse, who says there were as many as 90,000 people infected with the disease in China alone.

Similarly, in late January on Twitter, an account disguised as a news outlet shared an audio clip that claimed that the time, 100,000 people have been infected.

It’s worth noting that there’s legitimate doubt about whether the Chinese government is accurately reporting the extent of the virus’ impact. At least eight people have been arrested by the Chinese government for spreading hoaxes, according to reporting from the Poynter Institute in January. On the popular Chinese social media app WeChat, some have said that frontline reports by medical workers are being taken down.

Still, the exact number of people infected by the coronavirus remains unknown.
False: A teen on TikTok is the first case in Canada

On TikTok, some teenagers have pretended to be infected with the virus. One student in Vancouver posted a popular video falsely claiming his friend had the first Canadian confirmed case of coronavirus. The video showed a teenager vomiting in school trash cans and wearing a mask around campus. In an interview with the Daily Beast, a spokesperson for the British Columbia Department of Health confirmed that the video is fake. At the time, the only confirmed case of coronavirus in British Columbia, at the time of the video was posted, was a man in his 40s. 

A screenshot of one of the TikTok coronavirus videos that was taken down.

TikTok appears to have deleted the original viral video which had over 4.1 million views, but a similar video, posted by the same user, showed a teen alleging a classmate had contracted the virus remained up as of February 20. That morning, the company said it released a feature directing users to trusted sources of information, like the WHO, when they search for coronavirus-related content in the app.

False: The Chinese government built a hospital overnight

It’s worth noting that the Chinese state media has also been spreading false information. As BuzzFeed News first pointed out, two state media outlets — Global Times and People’s Daily — circulated an image of a newly constructed building and claimed it was a hospital in Wuhan that was constructed in just 16 hours. In fact, the building in the image was an apartment building more than 600 miles away.


This is just one example of how the Chinese government and state-backed organizations have used false or misleading information to portray the outbreak as being under control.
How tech platforms are responding

Every social media company Recode reached said they were working to reduce the impact of false information about the coronavirus in some way, to varying extents.

In addition to taking down conspiracy theories and provided WHO free advertising, Facebook said it’s also working on “blocking people from running ads that try to exploit the situation.” Zuckerberg said, as an example, that would include a company promoting a product that claimed to cure a disease. He also said,: “Researchers are already using aggregated and anonymized Facebook data — including mobility data and population density maps — to better understand how the virus is spreading.

In a statement, Twitter appeared to echo some of the latest steps being taken by Facebook. The company said it would “halt any attempt by advertisers to opportunistically use the Covid-19 outbreak to target inappropriate ads,” that it was working with fact checkers to promote accurate content on the site, and that it was also supplying data to researchers.

Twitter also said it’s not “seeing significant coordinated platform manipulation efforts around these issues.” This doesn’t mean that there’s not false information about coronavirus on Twitter, as the hoaxes we mentioned earlier prove. Twitter’s response simply indicates that the company hasn’t found any evidence of intentional disinformation campaigns by someone, like a state actor or political group.

In the early days of the outbreak, Facebook’s approach was to put fact-checking alerts on false content related to conspiracy theories. But at the end of January, the company announced that it would take additional action:

We will also start to remove content with false claims or conspiracy theories that have been flagged by leading global health organizations and local health authorities that could cause harm to people who believe them. We are doing this as an extension of our existing policies to remove content that could cause physical harm. We’re focusing on claims that are designed to discourage treatment or taking appropriate precautions. This includes claims related to false cures or prevention methods — like drinking bleach cures the coronavirus — or claims that create confusion about health resources that are available. We will also block or restrict hashtags used to spread misinformation on Instagram, and are conducting proactive sweeps to find and remove as much of this content as we can.

Twitter has also placed a warning label linking to the CDC when users search “coronavirus.”Twitter shows a banner linking to the Centers for Disease Control and Prevention when you search for “coronavirus” on the platform.

Meanwhile, starting in late January, TikTok began issuing a notification for users when they search for the “coronavirus” hashtag in the app. The alert encourages users to look to “trusted sources” like the WHO for accurate information and to report content that might violate its community guidelines. TikTok told Recode in a statement that its guidelines “do not permit misinformation that could cause harm to our community or the larger public,” adding that “[w]hile we encourage our users to have respectful conversations about the subjects that matter to them, we remove deliberate attempts to misrepresent authoritative sources of news.”

YouTube has its own version of an advisory. Beginning in late January, the video platform began showing short previews of text-based news articles about the coronavirus in search results. If you search “coronavirus” on YouTube, for example, you’re linked to a WHO landing page about the novel coronavirus. YouTube told Recode that false information generally does not violate the platform’s rules unless it involves hate speech, harassment, scams, or inciting violence. The company also said it aims to reduce the recommendations of what it deems “borderline content” or videos that could misinform users in harmful ways — including false information about coronavirus.
