Definition: A disease is a particular abnormal condition, a disorder of a structure or function, that affects part or all of an organism .
The causal study of disease is called pathology. Disease is often construed as a medical condition associated with specific symptoms and signs.
A disease differs from a syndrome , which is a collection of signs or symptoms that occur together. However, for historical reasons, many conditions have been identified, yet continue to be referred to as "syndromes". Furthermore, numerous conditions of unknown etiology are referred to as "diseases" in many contexts.
