How is the "Red Death" described in the story, The Masque of the Red Death?

The "Red Death" is described as the most deadly plague ever, as "no pestilence had ever been so fatal, or so hideous." The symptoms of the plague include "sharp pains, and sudden dizziness, and then profuse bleeding at the pores." The "scarlet stains" on the body, and especially the face, of its victims are the "pest ban" or first visible signs of the disease. Once the stains appear, the victim has only thirty minutes before death.
