WHO wishes Trumps 'a full and swift recovery'

"Our prayers are with them," Tedros said at the start of the media briefing, after U.S. administration officials said Trump is experiencing mild symptoms after testing positive for the deadly coronavirus.

The couple went into quarantine, the White House said.

WHO's emergency expert Mike Ryan called COVID-19 a 'nasty virus' that 'can cause severe disease particularly in older individuals with underlying conditions."

Trump has played down the threat of the coronavirus pandemic from the outset despite repeated warnings from the WHO about the severity of the pandemic.

Trump has savaged the WHO for its handling of the pandemic and accused it of being too close to China, where the virus emerged.

The U.S., formerly top donor of the Geneva-based body, has said it plans to withdraw and cut off funding.
