Anthony Fauci, the federal government's top infectious disease expert, is putting himself in "modified quarantine" after possibly being exposed to a White House staffer with coronavirus, CNN reported Saturday.
Fauci, 79, told CNN correspondent Jake Tapper that the contact was "low risk" _ meaning he did not have direct contact with the sick staffer.
A test Friday found Fauci did not have COVID-19, CNN reported.
Fauci plans to be tested every day, and will work from home wearing a mask, the network said. Fauci might eventually go to his office at the National Institute of Allergies and Infectious Diseases, where he is the only person working, said the news channel.
It's unclear which White House staffer may have exposed Fauci to the virus. However, Vice President Mike Pence's press secretary Katie Miller, who tested positive on Friday, often sits in on White House coronavirus task force meetings that Fauci attends.
Miller is married to Stephen Miller, a top Trump aide.
Two other members of the coronavirus task force are also in quarantine after "low risk exposure" to someone in the White House.
Dr. Robert Redfield, director of the Centers for Disease Control and Prevention, will be "teleworking for the next two weeks," the CDC said Saturday evening. Redfield feels fine and has no symptoms, the statement said.
Food and Drug Administration Commissioner Stephen Hahn has also come in contact with someone who tested positive, that agency said in a statement.
Fauci, Redfield and Hahn are to testify to a Senate committee on Tuesday. They'll be allowed to testify by video, said Sen. Lamar Alexander, R-Tenn., chairman of the committee.
Fauci, a medical doctor, has been director of the National Institute of Allergies and Infectious Diseases since 1984.
