Functional cure, also referred to as a "remission," is a term used to describe the state of a person who is infected with a chronic disease that is not completely cured, but the symptoms are controlled to such an extent that the patient can enjoy a good quality of life. Synonyms for functional cure include partial remission, control, management, suppression, containment, and remission without clearance. Functional cure is often used in the context of HIV treatment, where antiretroviral therapy (ART) can suppress viral replication to such an extent that the individual's viral load is undetectable for an extended period of time. Other conditions where functional cure may be achievable include hepatitis B and C and certain types of cancer.
