Rash definition
Rash is a general term for a broad range of SKIN eruptions. A rash is a symptom rather than itself a health condition and may accompany numerous dermatologic or systemic conditions. Viral and bacterial infections, immune and autoimmune responses, toxic contacts, systemic illnesses, chronic health conditions, and PARASITIC INFESTATIONS often cause rashes. Many rashes are so generalized that they are difficult to diagnose in the absence of other symptoms. Some rashes are so distinctive that their diagnosis requires no further symptoms. Nearly all rashes go away when the underlying health condition is resolved. Treatment for the rash may consist of approaches to mitigate symptoms, typically itching, and may include topical and oral ANTIHISTAMINE MEDICATIONS.
