By definition, a chronic disease is one that persists for a long time, typically lasting three months or more. Chronic diseases generally cannot be prevented by vaccines nor do they simply disappear. A diagnosis of chronic fatigue syndrome (CFS) includes a person having chronic fatigue for 6 or more consecutive months, among other diagnostic criteria. There is no cure for chronic fatigue syndrome.
