(Reuters) - Three senior officials guiding the U.S. response to the coronavirus pandemic were in self-quarantine on Saturday after coming into contact with someone who had tested positive for the disease, their agencies and spokesmen said.

Anthony Fauci, a high-profile member of the White House coronavirus response team, is considered to be at relatively low risk based on the degree of his exposure, according to a representative for the National Institute of Allergy and Infectious Diseases.
