Rashes

Rashes, affections of the skin, characterised by a red superficial efflorescence, diffused or in patches, disappearing under pressure, and usually ending in desquamation. To this division of cutaneous disorders belong Measles, Scarlatina (or Scarlet Fever), Erysipelas, Erythema, Roseola (or Scarlet Rash), and Nettle Rash. Of these rashes Measles, Scarlatina, and Erysipelas are rather to be regarded as fevers or blood diseases than as cutaneous diseases in the true sense of the phrase.
