During the COVID-19 pandemic, Facebook has taken a public stance against bogus health claims that discourage people from taking proper precautions against the virus. The company even gave the World Health Organization free advertising to help fight misinformation.

But research from Avaaz, a global non-profit that works to protect democracies from disinformation on social media, shows that global health misinformation accumulated an estimated 3.8 billion views on Facebook in the past year. The conspiracies circulating on Facebook can be fatal — some of them suggest ingesting poisonous substances, while others tell people not to wear masks or to shun vaccines.

In this podcast extra, Bob talks to Fadi Quran, campaign director at Avaaz, about the "superspreader" pages that are amassing these page views, the most popular health conspiracies on Facebook, and whether there's any hope that Facebook will address the proliferation of disinformation on its site.
