Recrudescence

Recrudescence is the revival of material or behavior that had previously been stabilized, settled, or diminished. In medicine, it is the recurrence of symptoms in a patient whose blood stream infection has previously been at such a low level as not to be clinically demonstrable or cause symptoms, or the reappearance of a disease after it has been quiescent. For example, a clinical attack after parasites in the blood have dropped markedly and the disease has subsided.
