Symptom: Rash


advertisement
Rash: Rash of any type affecting the skin.
Introduction: There are many possible causes of a rash and any rash needs prompt investigation by a doctor or a dermatologist. Rashes can be caused by illnesses such as viruses (e.g chicken pox) or systemic conditions (e.g. lupus), by allergies such as hives or eczema, parasites like lice in scabies, by reactions to chemicals, and by numerous other causes. One of the most feared but less common rashes is that caused by meningococcal disease, which is a characteristic hemorrhagic rash, caused by bleeding of capillaries just under the skin (see hemorrhagic rash for more details). Any type of hemorrhagic rash is a medical emergency.
