U.S. Vice President Kamala Harris tested positive for COVID-19 on rapid and PCR tests on Tuesday, her spokesperson said.

"She has exhibited no symptoms, will isolate and continue to work from the vice president's residence," the spokesperson said in a statement.

Harris, 57, has not been a close contact to U.S. President Joe Biden or the first lady "due to their respective recent travel schedules," the statement said.

The vice president will follow CDC guidelines and the advice of her physicians and will return to the White House when she tests negative, it added.
