Viral infections, such as measles, rubella, roseola, fifth disease, varicella zoster, herpes or shingles 1. Bacterial infections, such as impetigo, scarlet fever or Lyme disease 1. 1. Fu...

Macular — Flat, red spots 2. Papular — Small, raised, solid bumps 3. Macular and papular — A combination 4. Papulosquamous — A combination of papules and scaly areas 5.

For example, the rash of a roseola viral infection usually lasts 1 to 2 days, whereas the rash of measles disappears within 6 to 7 days. Rashes caused by an antibiotic allergy may last 3 to 14 days, whereas diaper rash almost always clears up within 1 week (if diapers are changed frequently).Rashes resulting from lupus or dermatomyositis may last for an extended period of time.

The outlook for most rashes is excellent, especially after the cause has been identified accurately. In severe allergic reactions, a patient can die within minutes without immediate medical treatment. With proper treatment, recovery usually is complete. However, the patient remains at risk of future severe reactions if he or she is exposed to the same allergy-producing agent. For this reason, a prescription for a self-injection pen containing epinephrine for emergencies usually is recommended...
