Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID) and Chief Medical Advisor to President Joe Biden, has tested positive for COVID, the National Institutes of Health announced Wednesday.

Dr. Fauci, who was also one of the lead members of the White House Coronavirus Task Force under former President Donald Trump, tested positive on a rapid antigen test and is experiencing "mild symptoms."

The 81-year-old is fully vaccinated and has been boosted twice and has not been in close contact with President Biden or any other government officials, the NIH said in a release. 

"Dr. 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," the release concludes.
