A growing body of research suggests that the effects of COVID-19 do not end once the virus has left your body — and a new study has found that one symptom in particular is pretty common: lingering fatigue. “Data is showing this is not just an acute illness but that it has potentially long-term effects,” says Thomas A. Russo, MD, professor of medicine and chief of the Division of Infectious Diseases. Lingering fatigue isn’t unique to COVID-19. “Whenever someone has a physiological insult, whatever that may be, the body goes through an acute inflammatory process and then a repair process,” says Russo.
