US President Joe Biden has tested positive for Covid-19 and is experiencing “very mild symptoms”, the White House said on Thursday, becoming the second sitting president to be hit by the virus.

This is the first time Biden, 79, has tested positive for Covid-19. Biden, who is fully vaccinated and twice boosted, has begun taking the pill Paxlovid. In line with CDC guidelines, President Biden will isolate at the White House and continue all his duties fully during that time, White House Press Secretary Karine Jean-Pierre said.
