After recovering from an illness like the flu or mononucleosis, most of us will return to our normal lives without complications. But for some, viruses can linger in the body—sometimes for years—and reemerge, wreaking new havoc on the immune system and even triggering chronic diseases. In this episode: Virologist Maggie Bartlett explains how viruses—many of which are vaccine-preventable—can cause post-acute infection syndrome and what's needed to improve the diagnosis and treatment of these conditions.
