COVID isn’t just infecting you—it could be reactivating viruses that have been dormant in your body for years

(Fortune) You had COVID a few months ago and recovered—but things still aren’t quite right. When you stand up, you feel dizzy, and your heart races. Even routine tasks leave you feeling spent. And what was once a good night’s sleep no longer feels refreshing. Long COVID, right? It may not be so simple. A mild or even an asymptomatic case of COVID can cause reservoirs of some viruses you’ve previously battled to reactivate, potentially leading to symptoms of chronic fatigue syndrome—a condition that resembles long COVID, according to a recent study published in the journal Frontiers in Immunology.
