US President Donald Trump has tested negative for Covid-19 and he is not infectious to others, the White House physician has said.

It comes ten days after Mr Trump announced he had contracted the coronavirus.

In a memo released by the White House just hours before Mr Trump was due to resume holding campaign rallies, Dr Sean Conley said the president had tested negative on consecutive days using an Abbott Laboratories Binax NOW antigen card.

Dr Conley said the negative tests and other clinical and laboratory data "indicate a lack of detectable viral replication".

Mr Trump's medical team had determined that based on the data and guidelines from the US Centers for Disease Control and Prevention "the president is not infectious to others," Dr Conley said.

Mr Trump returns to the campaign trail tonight with a rally in Sanford, Florida, his first since he disclosed on 2 October that he tested positive for Covid-19.

Critics fault Mr Trump for failing to encourage supporters at campaign events, and even White House staff, to wear protective masks and abide by social-distancing guidelines. 

At least 11 close Trump aides have tested positive for the coronavirus.

Which White House staff members have tested positive for Covid-19?
