Nearly three years into the pandemic, Covid-19 stays stubbornly persistent. So, too, does misinformation concerning the virus.
As Covid cases, hospitalizations and deaths rise in parts of the country, myths and misleading narratives proceed to evolve and spread, exasperating overburdened doctors and evading content moderators.
What began in 2020 as rumors that forged doubt on the existence or seriousness of Covid quickly evolved into often outlandish claims about dangerous technology lurking in masks and the supposed miracle cures from unproven drugs, like ivermectin. Last yr’s vaccine rollout fueled one other wave of unfounded alarm. Now, along with all of the claims still being bandied about, there are conspiracy theories concerning the long-term effects of the treatments, researchers say.
The ideas still thrive on social media platforms, and the constant barrage, now a yearslong accumulation, has made it increasingly difficult for accurate advice to interrupt through, misinformation researchers say. That leaves people already affected by pandemic fatigue to develop into further inured to Covid’s continuing dangers and at risk of other harmful medical content.
“It’s easy to forget that health misinformation, including about Covid, can still contribute to people not getting vaccinated or creating stigmas,” said Megan Marrelli, the editorial director of Meedan, a nonprofit focused on digital literacy and data access. “We all know for a undeniable fact that health misinformation contributes to the spread of real-world disease.”
Twitter is of particular concern for researchers. The corporate recently gutted the teams chargeable for keeping dangerous or inaccurate material in check on the platform, stopped enforcing its Covid misinformation policy and started basing some content moderation decisions on public polls posted by its latest owner and chief executive, the billionaire Elon Musk.
From Nov. 1 to Dec. 5, Australian researchers collected greater than half 1,000,000 conspiratorial and misleading English-language tweets about Covid, using terms reminiscent of “deep state,” “hoax” and “bioweapon.” The tweets drew greater than 1.6 million likes and 580,000 retweets.
The researchers said the quantity of toxic material surged late last month with the discharge of a movie that included baseless claims that Covid vaccines set off “the best orchestrated die-off within the history of the world.”
Naomi Smith, a sociologist at Federation University Australia who helped conduct the research with Timothy Graham, a digital media expert at Queensland University of Technology, said Twitter’s misinformation policies helped tamp down anti-vaccination content that had been common on the platform in 2015 and 2016. From January 2020 to September 2022, Twitter suspended greater than 11,000 accounts over violations of its Covid misinformation policy.
Now, Dr. Smith said, the protective barriers are “falling over in real time, which is each interesting as an educational and absolutely terrifying.”
Inside Elon Musk’s Twitter
“Pre-Covid, individuals who believed in medical misinformation were generally just talking to one another, contained inside their very own little bubble, and also you needed to go and do a little bit of work to search out that bubble,” she said. “But now, you don’t should do any work to search out that information — it’s presented in your feed with another varieties of information.”
Several distinguished Twitter accounts that had been suspended for spreading unfounded claims about Covid have were reinstated in recent weeks, including those of Representative Marjorie Taylor Greene, a Georgia Republican, and Robert Malone, a vaccine skeptic.
Mr. Musk himself has used Twitter to weigh in on the pandemic, predicting in March 2020 that the USA was more likely to have “near zero latest cases” by the top of that April. (Greater than 100,000 positive tests were reported to the Centers for Disease Control and Prevention within the last week of the month.) This month, he took aim at Dr. Anthony S. Fauci, who will soon step down as President Biden’s top medical adviser and the longtime director of the National Institute of Allergy and Infectious Diseases. Mr. Musk said Dr. Fauci ought to be prosecuted.
Twitter didn’t reply to a request for comment. Other major social platforms, including TikTok and YouTube, said last week that they remained committed to combating Covid misinformation.
YouTube prohibits content — including videos, comments and links — about vaccines and Covid-19 that contradicts recommendations from the local health authorities or the World Health Organization. Facebook’s policy on Covid-19 content is greater than 4,500 words long. TikTok said it had removed greater than 250,000 videos for Covid misinformation and worked with partners reminiscent of its content advisory council to develop its policies and enforcement strategies. (Mr. Musk disbanded Twitter’s advisory council this month.)
However the platforms have struggled to implement their Covid rules.
Newsguard, a company that tracks online misinformation, found this fall that typing “covid vaccine” into TikTok caused it to suggest searches for “covid vaccine injury” and “covid vaccine warning,” while the identical query on Google led to recommendations for “walk-in covid vaccine” and “varieties of covid vaccines.” One search on TikTok for “mRNA vaccine” brought up five videos containing false claims inside the first 10 results, in keeping with researchers. TikTok said in an announcement that its community guidelines “clarify that we don’t allow harmful misinformation, including medical misinformation, and we are going to remove it from the platform.”
In years past, people would get medical advice from neighbors, or attempt to self-diagnose via Google search, said Dr. Anish Agarwal, an emergency physician in Philadelphia. Now, years into the pandemic, he still gets patients who consider “crazy” claims on social media that Covid vaccines will insert robots into their arms.
“We battle that each single day,” said Dr. Agarwal, who teaches on the University of Pennsylvania’s Perelman School of Medicine and serves as deputy director of Penn Medicine’s Center for Digital Health.
Online and offline discussions of the coronavirus are consistently shifting, with patients bringing him questions currently about booster shots and long Covid, Dr. Agarwal said. He has a grant from the National Institutes of Health to review the Covid-related social media habits of various populations.
“Moving forward, understanding our behaviors and thoughts around Covid will probably also shine light on how individuals interact with other health information on social media, how we are able to actually use social media to combat misinformation,” he said.
Years of lies and rumors about Covid have had a contagion effect, damaging public acceptance of all vaccines, said Heidi J. Larson, the director of the Vaccine Confidence Project on the London School of Hygiene & Tropical Medicine.
“The Covid rumors should not going to go away — they’re going to get repurposed, they usually’re going to adapt,” she said. “We will’t delete this. Nobody company can fix this.”
Some efforts to slow the spread of misinformation concerning the virus have bumped up against First Amendment concerns.
A law that California passed several months ago, and that is about to take effect next month, would punish doctors for spreading false details about Covid vaccines. It already faces legal challenges from plaintiffs who describe the regulation as an unconstitutional infringement of free speech. Tech firms including Meta, Google and Twitter have faced lawsuits this yr from individuals who were barred over Covid misinformation and claim that the businesses overreached of their content moderation efforts, while other suits have accused the platforms of not doing enough to rein in misleading narratives concerning the pandemic.
Dr. Graham Walker, an emergency physician in San Francisco, said the rumors spreading online concerning the pandemic drove him and plenty of of his colleagues to social media to attempt to correct inaccuracies. He has posted several Twitter threads with greater than 100 evidence-packed tweets attempting to debunk misinformation concerning the coronavirus.
But this yr, he said he felt increasingly defeated by the onslaught of toxic content about a wide range of medical issues. He left Twitter after the corporate abandoned its Covid misinformation policy.
“I started to think that this was not a winning battle,” he said. “It doesn’t feel like a good fight.”
Now, Dr. Walker said, he’s watching as a “tripledemic” of Covid-19, R.S.V. and influenza bombards the health care system, causing emergency room waits in some hospitals to surge from lower than an hour to 6 hours. Misinformation about easily available treatments is not less than partly responsible, he said.
“If we had a bigger uptick in vaccinations with essentially the most recent vaccines, we probably would have a smaller number of individuals getting extremely unwell with Covid, and that’s definitely going to make a dent in hospitalization numbers,” he said. “Truthfully, at this point, we are going to take any dent we are able to get.”
