Pressure has been mounting on Facebook and Twitter to do more to tackle misinformation both about the pandemic and the US election. For that reason, their decisive action on Trump's recent post promoting false claims about the severity of coronavirus will be welcomed.
That said, Trump's comments about the flu - and those yesterday saying "Don't be afraid of Covid" - have already started to fuel conspiracy theories online.
Posts in pro-Trump and anti-mask Facebook groups have shared the comments with captions about the pandemic not being real, or not very serious. They have also used it to encourage others not to follow health guidance like wearing a mask or social distancing.
Early on in the pandemic, the BBC investigated the human cost of misinformation, including those who fell seriously ill because social media posts led them to doubt the reality or severity of the pandemic and ignore advice.
The hope will be that this action from social media sites could reduce the risk of that happening - but those who may have already been exposed to this disinformation could be impacted.
And all eyes will be on social media sites to see if they keep up this approach to tackling disinformation - coronavirus, political or otherwise - especially from the US Election candidates as polling day nears.
