Dormant Viruses Re-Emerge in Patients with Lingering Sepsis, Signaling Immune Suppression

A provocative study links prolonged episodes of sepsis — a life-threatening infection and leading cause of death in hospitals — to the reactivation of otherwise dormant viruses in the body. In healthy people, such latent viruses are kept in check by the immune system. But a new study provides strong evidence that when sepsis lingers for more than a few days, which is common, viruses re-emerge and enter the bloodstream, signaling that the immune system has become suppressed.
