Rash. Certain febrile disorders are attended by characteristic cutaneous eruptions or rashes. These maladies are known as the exanthemata (small-pox, chicken-pox, scarlet fever, measles, typhoid and typhus fevers). The term rash is sometimes applied to other forms of skin eruption, as, for example, nettle-rash, and the rashes which are produced by the administration of certain drugs.
