Anthrax is a serious bacterial infection sustained by Bacillus anthracis and occurring in most mammals, especially grazing herbivors, but it can also involve humans when bacterial endospores enter the body through abrasions in the skin or by inhalation or ingestion. Human disease results from contact with infected animals or contaminated animal products, while there are no known cases of human-to-human transmission. ⋯ For centuries, anthrax has caused disease in animals and only a few cases in humans, with some outbreaks in developing countries. Today, after the new events in the United States, at least 17 nations are believed to have offensive biological weapon programs, and this old bacterial infection became a modern menace to world safety.
