US President Donald Trump’s diagnosis as COVID-19 positive adds extraordinary drama to an already fast-moving and tumultuous US election campaign.
Here are the five facts about the infection of the US president:
1. Where is Trump now?
Trump has spent his days since diagnosis in a military hospital just outside Washington to undergo treatment for the coronavirus, but will continue to work, the White House said on Friday.
Press secretary Kayleigh McEnany told reporters Trump “will be working from the presidential offices at Walter Reed for the next few days.”
The president’s campaign manager Bill Stepien said earlier in the day that all previously announced campaign events ahead of the November 3 election would be held virtually or postponed.
The positive COVID-19 test also raises questions about whether two debates with Democrat Joe Biden later this month will go ahead as planned.
In a press conference on Sunday, doctor Brian Garibaldi said that the medical team hoped that Trump would be discharged by Monday: “Our hope is to plan for a discharge as early as tomorrow to the White House, where he can continue his treatment course.”
2. What treatment is he receiving?
White House physician Sean Conley said on Friday that the president was “fatigued but in good spirits” and was taking an experimental COVID-19 treatment.
Trump received a single dose of Regeneron’s antibody cocktail, Conley said in a letter. On Saturday he received a second dose.
The treatment is undergoing clinical trials but has not yet been approved by regulators.
As a 74-year-old man, Trump is “at higher risk for severe illness” from the virus, according to the US health agency CDC.
Trump will be monitored closely for the wide range of common symptoms which include fever, chills, cough, shortness of breath, fatigue, muscle ache and headache.
3. What are his symptoms?
On Thursday, Trump did not immediately isolate after his close aide Hope Hicks tested positive.
Instead, he boarded a plane to New Jersey, where he attended a fundraiser at his golf club and delivered a speech surrounded by dozens of people before returning to the White House.
The New York Times quoted unnamed sources saying Trump showed mild symptoms at the Thursday night event, seeming lethargic.
One source told the paper he had displayed cold-like symptoms.
On Friday, Trump’s chief of staff Mark Meadows said that the president had “mild symptoms”.
4. How did he get it?
It is unknown how Trump contracted the coronavirus, but he has defied medical advice by seldom wearing a mask and often meeting with large groups of people.
White House alarm bells started to ring when Hicks tested positive. She is a central figure in Trump’s inner circle and travelled with him several times over the past week.
She was also closely involved in his preparations for Tuesday’s debate against Joe Biden. At the televised event, many of Trump’s guests did not wear masks.
5. Who else in the White House has it?
Trump announced that his wife, Melania, also tested positive for the virus in his tweet announcing their diagnoses on Friday morning.
Vice President Mike Pence, who would step in if Trump falls seriously ill, tested negative later on Friday, as did Trump’s teenage son Barron.
Ivanka Trump and Jared Kushner, the president’s daughter and son-in-law who are top White House advisers, also tested negative, as well as Secretary of State Mike Pompeo, Treasury Secretary Steven Mnuchin and Health and Human Services Secretary Alex Azar.
Ronna McDaniel, the chairwoman of the Republican National Committee, tested positive several days ago, it was announced on Friday.
Many other senior politicians, officials and military officers who work or visit the White House were tested on Friday.
