YouTube, a unit of Google, acknowledges that it pays close attention to the advice of public-health authorities, including the World Health Organization. The UN body doesn't control YouTube or any other content publisher or platform, but WHO information and advice is considered in decisions about banning "medical misinformation" from the service. "Anything that would go against World Health Organization recommendations would be a violation of our policy," CEO Susan Wojcicki said in an interview with CNN.
A policy statement on YouTube's help pages explains that the company "doesn't allow content about COVID-19 that poses a serious risk of egregious harm," listing many examples of the kind of COVID-related content it won't permit.
