US President Joe Biden has tested negative for Covid-19 days after getting a second bout of the virus, his doctor says

Mr. Biden, 79, first tested positive for the virus 15 days ago. He had been in isolation for a second time after getting what White House doctor Kevin O'Connor suggested as a "rebound" case. The president will now return to public life after he tested negative on both Saturday and Sunday. Dr. O'Connor said on Saturday that "the president continues to feel very well". Mr. Biden - who is fully vaccinated and has twice received booster jabs - first tested positive for Covid-19 on 21 July. He tested negative six days later, only to then test positive again on 30 July. The president faced mild symptoms while he had the virus, including a runny nose and fatigue, and continued working while in isolation.
