Fauci, 81, has not had recent close contact with President Joe Biden or other senior officials, according to the National Institute of Allergy and Infectious Diseases. Fauci, who has mild symptoms, tested positive for antigen, according to the NIAID. He was fully vaccinated and received two memorabilia, the NIAID said in a statement. On June 11, Fauci went to the College of the Holy Cross in Worcester, Massachusetts, where the college renamed the science center the Anthony S. Fauci Integrated Science Complex. Fauci was seen with and without a mask in photographs. Fauci told CNN last month that he had never tested positive for COVID-19. In April, Fauci did not attend the White House correspondents’ dinner. “Each of us, in our own personal way, has to make an assessment of the risk you are willing to take to become infected,” Fauci told CNN in April. “In general, the risk is low, but I made a personal assessment. “I am 81 years old and if I get infected, I have a much higher risk.” Fauci was scheduled to appear before the Senate Health, Education, Labor and Pensions Committee on Thursday to give a briefing on the federal response to the pandemic. “Dr Fauci will be isolated and will continue to work from home,” the statement said. “Dr. Fauci will follow the COVID-19 guidelines of the Centers for Disease Control and Prevention and his doctor’s medical advice and will return to the NIH when a negative test comes out.” ABC News’ Arielle Mitropoulos and Emily Shapiro contributed to this report.
