How long did a person live after contracting the red death?

In Edgar Allan Poe's short story "The Masque of the Red Death," the disease known as the Red Death is described as causing swift and gruesome symptoms, typically leading to death within half an hour after onset. The rapid progression of the illness is central to the story's themes of inevitability and the futility of trying to escape death. Thus, a person who contracted the Red Death would live only a very short time, often less than an hour.
