What Keeps Dr. Anthony Fauci Awake at Night

That's the crux of a new editorial penned by Fauci, who became a household name in 2020 after quietly leading the U.S. National Institutes of Allergy and Infectious Diseases for nearly four decades.

Those years saw many challenges, including the HIV/AIDS crisis. Yet the thing that persistently kept him up at night, Fauci says, was the threat of a deadly pandemic caused by a virus that spreads through the air. When that threat turned into a reality in 2020, that was the "nightmare."

Now a professor at Georgetown University in Washington, D.C., Fauci no longer has "pandemic response" as a job duty. But he is still thinking about the next pandemic -- which is a matter of "when," not "if."
