Since the announcement, First Lady Melania Trump has also confirmed that they are currently quarantining at their home.
"As too many Americans have done this year, @potus & I are quarantining at home after testing positive for COVID-19," she announced on Twitter. "We are feeling good & I have postponed all upcoming engagements."
"Please be sure you are staying safe & we will all get through this together."
As well as the President himself, one of his personal valets has also tested positive along with Kimberly Guilfoyle, who is currently dating Mr Trump's oldest son, Donald Trump Jr.
Trump has recently been keeping an intense travel schedule across the country, among large crowds of people in preparation for the U.S. Presidential election on November 3.
However, if the U.S. President becomes too ill to lead the United States, his vice president Mike Pence will take his place. And if Pence is also incapacitated, House Speaker Nancy Pelosi would be the most likely person to take over.
