In
medicine, a chronic disease is a
disease that is long-lasting or recurrent. The term chronic describes the
course of the disease, or its rate of onset and development. A chronic
course is distinguished from a
recurrent course; recurrent diseases
relapse repeatedly, with periods of
remission in between. As an adjective, chronic can refer to a persistent and lasting medical condition. Chronicity is usually applied to a condition that lasts more than three months. Diabetes is a good example.
