COVID-19: “There are a lot of myths. We have to be careful what to read” – Dr Chris Barbara


Speaking to Drew and Noel on Bay Chats yesterday, Dr Chris Barbara, Head of the Pathology Department at Mater Dei Hospital and Malta’s top Virologist said that there are a lot of myths on the internet about COVID-19: where it came from; what the symptoms are; what can be done to prevent, and so on and so forth.

“There are a lot of myths, we have to be very careful what we read,” Dr Barbara said, whilst adding that even amongst healthcare and infectious diseases professionals, sometimes it is hard to effectively determine the presence of COVID-19 just by analysing the person’s symptoms, which is why everyone all over the world is relying on the various testing measures available.



It is with this in mind that tech companies all over the world are stepping up their fight against bad or false Coronavirus information.

This comes as potentially dangerous coronavirus misinformation has spread from continent to continent like the pandemic itself, forcing the world’s largest tech companies to take unprecedented action to protect public health.

Facebook, Google and others have begun using algorithms, new rules and factual warnings to knock down harmful coronavirus conspiracy theories, questionable ads and unproven remedies that regularly crop up on their services — and which could jeopardize lives.



Social Media Platforms and search engines are now working faster than ever to scrub their sites of coronavirus misinformation.

“It was definitely, within the companies, a shift,” said Andy Pattison, manager of digital solutions for the World Health Organization, who for nearly two years has urged companies like Facebook to take more aggressive action against anti-vaccination misinformation.

Pattison said he and his team now directly flag misleading coronavirus information and, at times, lobby for it to be removed from Facebook, Google and Google’s YouTube service.



Twitter and Facebook began cracking down in unprecedented ways on posts promoting unverified treatments.

Twitter deleted a post by Trump’s personal attorney Rudy Giuliani that described hydroxychloroqine, a cousin to chloroquine, as “100 percent effective” against coronavirus. The company also removed a tweet from Fox News personality Laura Ingraham touting what she called the drug’s “promising results.”

Other widely shared claims that hydroxychloroquine cures COVID-19 live on. A conservative radio host’s tweet claiming that “ALL hospitals and health care workers are using it with total success” has been shared more than 12,000 times.

In what may be a first, Facebook removed a post from Brazilian President Jair Bolsanaro, who promoted hydroxychloroquine as “working in every place” to treat coronavirus. Twitter also removed an associated video.



Other sites have also tightened their policies.

YouTube began removing videos that claimed coronavirus was caused by 5G wireless networks last week. Some of the videos had racked up hundreds of thousands of views. Google searches for “5G” and “coronavirus” now redirect users news videos debunking the theory.

Facebook-owned private messaging service WhatsApp has limited how many chats users can forward messages to in an effort to limit the spread of COVID-19 misinformation. Since WhatsApp encrypts all messages, it can’t read them to determine if they contain misinformation.











The pandemic has thrown up new challenges to content moderation. Early on, health considerations forced the contractors that employ human moderators to send most of them home, where for privacy reasons they couldn’t do their jobs. Facebook eventually shifted some of that work to in-house employees and leaned more heavily on artificial-intelligence programs. More recently, it has made new arrangements for contract moderators to do their jobs remotely.

Meanwhile, bogus ads for masks, hand sanitizer and unregulated blood tests for COVID-19 still appear on Facebook and Google. And one North Carolina man with 44,000 YouTube subscribers who complained that his videos promoting the 5G and coronavirus theory were removed is now using the platform to hawk $99 subscriptions to view his videos.

The tech platforms point out they are putting facts about the virus from news outlets, fact checkers, and health officials in front of their users when their safeguards fail.

Google “coronavirus” and you’ll be directed to your local health department. Search on Twitter for “coronavirus hoax” and you’ll get a link to the U.S. Centers for Disease Control and Prevention. Watch a coronavirus conspiracy theory video on YouTube and you’ll see a label promoting legitimate news outlets and COVID-19 information from the CDC hovering over it.
