First, there were conspiratorial whispers on social media that the coronavirus had been cooked up in a secret government lab in China. Then there were bogus medicines: gels, liquids and powders that immunized against the virus.
And then there were the false claims about governments and celebrities and racial unrest. Taiwan was covering up virus deaths, and the illness was spiraling out of control. Bill Gates, the Microsoft co-founder who now runs a philanthropic organization, was behind the spread of the virus. Italians were marching in the streets, accusing Chinese people of bringing the illness to their country. None of it was true.
As the coronavirus has spread across the world, so too has misinformation about it, despite an aggressive effort by social media companies to prevent its dissemination. Facebook, Google and Twitter said they were removing misinformation about the coronavirus as fast as they could find it, and were working with the World Health Organization and other government organizations to ensure people got accurate information.
But a search by The New York Times found dozens of videos, photographs and written posts on each of the social media platforms that appeared to have slipped through the cracks. The posts were not limited to English. Many were originally in languages ranging from Hindi and Urdu to Hebrew and Farsi, reflecting the trajectory of the virus as it has traveled around the world.
Security researchers have even found that hackers were setting up threadbare websites that claimed to have information about the coronavirus. The sites were actually digital traps, aimed at stealing personal data or breaking into the devices of people who landed on them.
The spread of false and malicious content about the coronavirus has been a stark reminder of the uphill battle fought by researchers and internet companies. Even when the companies are determined to protect the truth, they are often outgunned and outwitted by the internet’s liars and thieves.
There is so much inaccurate information about the virus, the W.H.O. has said it was confronting a “infodemic.”
“I see misinformation about the coronavirus everywhere. Some people are panicking, and looking to magical cures, and other people are spreading conspiracies,” said Austin Chiang, a gastroenterologist at Jefferson University Hospital in Philadelphia.
In Taiwan, virus-related misinformation on social media has fed concerns that China might be using the crisis to undermine the government of the self-ruling island.
In recent weeks, there have been posts on Facebook and other sites claiming that Taiwan has concealed large numbers of coronavirus infections. There have been fake but official-looking documents promising giveaways of face masks and vaccines. A screen capture from a television news broadcast was doctored to say that President Tsai Ing-wen had contracted the disease and was in quarantine. In a statement to The Times, Taiwan’s foreign minister, Joseph Wu, blamed China’s “internet armies” for the deluge of falsehoods, though his office declined to elaborate on how he came to that conclusion. China’s Taiwan Affairs Office didn’t respond to a faxed request for comment.
