In this disease, the eruption consists of patches of little blisters or vesicles, each of which is surrounded by a little ring of inflamed tissue. The eruption is most always accompanied by some fever and pain, or smarting, in the affected part. They do not generally burst, but dry up, the contents first becoming milky and then a crust forming which falls off in a few days, leaving a reddish stain in the skin. A very common form of the disease is known as shingles, in which the eruption occurs on one side of the trunk, following the course of the nerve. The technical name of this form of the disease is Herpes Zoster. It is supposed to be due to an inflammation of a nerve of sensation. There is a popular notion that if this disease encircles the body, the patient will die. This idea is incorrect, however. The disease never does encircle the body from the fact that the nerve extends only to the central line, though cases have occurred in which corresponding nerves on opposite sides of the body were affected, making a seeming exception to the general rule. The result is no more serious in these cast's, however, than in others. A still more common form of herpes is met in the little sores which form about the mouth in fevers, known as cold-sores or fever-blisters. A similar eruption sometimes occurs about the genital organs.

The Treatment of Herpes or Cold or Fever Sores

The parts should be protected from irritation by the friction of clothing, and rubbing should be particularly avoided, as the disease will be greatly aggravated thereby, in some cases, scars being formed. An attack of shingles, if not properly treated, sometimes leaves a neuralgia behind it. The affected parts should be dusted with powdered starch, or smeared with carbolic-acid ointment,-ten drops of carbolic add to the ounce of vaseline,-covered with cotton or wool. The neuralgia, which sometimes continues afterward, should be treated by fomentations. The formation of cold-sores can generally be checked by the application of spirits of camphor to each blister.
