The disease is any adverse variation from an organism's normal structural or functional condition that is often accompanied by a set of symptoms and is distinct from physical damage in origin. A sick organism frequently displays symptoms or indicators that point to its aberrant condition. Thus, it is necessary to comprehend an organism's normal state in order to identify the symptoms of sickness. However, there is not always a clear distinction between illness and wellness.
Synonyms: illness, ailment, sickness
