What is the prognosis for anthrax?
Untreated anthrax is often fatal, but death is far less likely with appropriate care. Ten to twenty percent of patients will die from anthrax of the skin (cutaneous anthrax) if it is not properly treated. All patients with inhalation (pulmonary) anthrax will die if untreated. Intestinal anthrax is fatal 25-75% of the time. Source: The Gale Group. Gale Encyclopedia of Medicine, 3rd ed.
