Scores of people could have been infected with COVID-19 by President Donald Trump after he revealed he had tested positive for the virus after a busy week of travelling that included eight flights, three rallies and a presidential debate.
The president announced that he and First Lady Melania had tested positive for coronavirus on Thursday night - after top aide Hope Hicks also tested positive after travelling with Trump multiple times over the last week.
The president tweeted to confirm the news shortly before 1am EST Friday, writing: 'Tonight, @FLOTUS and I tested positive for COVID-19. We will begin our quarantine and recovery process immediately. We will get through this TOGETHER!'
Fears that the president may have contracted the virus were raised after it was revealed Hicks had traveled on both Marine One, the presidential helicopter, and on Air Force One in the last seven days. She has also been pictured with Jared Kushner and other senior White House staff in that time.
With a busy presidential schedule, Trump and Hicks have come into contact with a number of other high-profile officials and members of the public in the last week.
In that time, Trump has traveled across seven states including New Jersey, Ohio, Florida, Minneapolis, Virginia, Pennsylvania and Georgia, as well as the DC.
He has taken part in three campaign rallies, has taken four round-trips on Air Force One and at least two flights on Marine One.
He also took part in the presidential debate against Democratic nominee Joe Biden, which he traveled to with at least 20 people.
He also held a number of press conferences - including to formally nominate his Supreme Court pick - and attended several fundraisers, including one just hours before his positive diagnosis was revealed.

The president has not confirmed when his last negative coronavirus test was, so it is currently unclear how many days Trump could have been spreading the virus for.
Until the time-frame of his last negative test is specified, there will be a number of senior officials concerned about the contact they have had with the president, and many will have to quarantine following the news until they can get tested.
All his adult children - Ivanka, Eric, Tiffany and Donald Trump Jr. - attended the debate against Biden on Thursday, while the eldest three brought Kimberly Guilfoyle, Lara Trump and Jared Kushner, while Tiffany went on her own.
Officials including Vice President Mike Pence, press secretary Kayleigh McEnany, White House social media director Dan Scavino, special assistant to the President and White House trip director William Russell, and director of the White House personnel John McEntee have all come into contact with Hicks or Trump.
White House Counsel Pat Cipollone, White House Chief of Staff Mark Meadows and Senate Majority Leader Mitch McConnell have also come into contact with Mike Pence in the last week.
