He is not considered a close contact to the president and has only mild symptoms.

Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and Chief Medical Advisor to President Joe Biden, tested positive for COVID-19 on a rapid antigen test.

He is fully vaccinated and has been boosted twice.

Fauci will isolate and continue to work from his home. He has not recently been in close contact with Biden or other senior government officials.

Fauci will follow the COVID-19 guidelines of the Centers for Disease Control and Prevention and medical advice from his physician and return to the NIH when he tests negative.

NIAID conducts and supports research to study the causes of infectious and immune-mediated diseases, and to develop better means of preventing, diagnosing, and treating these illnesses.
