Rare and Deadly Diseases
So goes Richard Preston's description of an Ebola sufferer in his account of the Ebola outbreaks in Zaire, The Hot Zone. Ebola is a hemorrhagic disease or fever, meaning it is characterized by bleeding. Other hemorrhagic diseases include Marburg and hantavirus (discussed later in this section).
A hemorrhagic fever is one characterized by severe bleeding, often from the mouth, stomach, and digestive tract. The term comes from the Greek Haima meaning blood and rhegnynai meaning to burst forth.
These diseases are very contagious and are passed through contact with the blood or body fluids of someone who is infected, or by touching a contaminated surface. Fortunately, neither Ebola nor Marburg have been seen in the United States yet.
