During a Q&A with Facebook Founder and CEO Mark Zuckerberg, Fauci discussed the group of people health experts have dubbed long haulers, consisting of 20 or 25 percent of people who have cleared the virus. In addition to the temporary fatigue signaling an infection, he noted that the majority of long haulers battle exhaustion long after the virus is gone.
