Social networking site Facebook has deleted a post in which US President Donald Trump had claimed Covid-19 was "less lethal" than the flu. He wrote the US had "learned to live with" flu season, "just like we are learning to live with Covid, in most populations far less lethal!!!" Twitter hid the same message behind a warning about "spreading misleading and potentially harmful information", the BBC reported on Tuesday.

Users have to click past the alert to read the tweet. Trump is at the White House after three days of hospital treatment having tested positive for the virus. "We remove incorrect information about the severity of Covid-19, and have now removed this post," said Andy Stone, policy communications manager at Facebook.
