What is anthrax?
Anthrax is a rare infectious disease caused by the bacterium Bacillus anthracis. Anthrax occurs naturally around the world in wild and domestic hoofed animals, especially cattle, sheep, goats, camels and antelopes. It can also occur in humans when they are exposed to the bacterium, usually through handling animals or animal hides. There are three forms of anthrax infection: cutaneous (skin), inhalation (lungs) and gastrointestinal (stomach and intestine). If people have been intentionally exposed, as in a bioterrorist release, contact with skin would be the most likely route of exposure. Breathing in the spores that have been spread through the air could cause inhalation anthrax.
How common is anthrax and who can get it?
Anthrax can be found around the world. It is most common in agricultural regions where it occurs in animals. It is more common in developing countries or countries without veterinary public health programs. Anthrax is reported more often in some regions of the world (South and Central America, Southern and Eastern Europe, Asia, Africa, the Caribbean and the Middle East) than in others. It has been extremely rare in the United States in recent decades, and until cases in Florida and New York City in 2001, has been limited to the cutaneous (skin) form. When anthrax affects humans, it is usually due to an occupational exposure to infected animals or their products. However, anthrax is considered to be one of a number of potential agents for use in biological terrorism.
How is anthrax spread?
Anthrax is usually spread in the form of a spore. (A spore is a dormant form that certain bacteria take when they have no food supply. Spores can grow and cause disease when better conditions are present, as in the human body.) Anthrax is generally spread in one of three ways. Most persons who are exposed to anthrax become ill within one week but can take as long as 42 days for inhalation anthrax:
Skin (cutaneous) - Most anthrax infections occur when people touch contaminated animal products like wool, bone, hair and hide. The infection occurs when the bacteria enters a cut or scratch in the skin.
Inhalation (lung) - Some anthrax infections occur when people breathe in the spores of the bacteria.
Gastrointestinal - Some people may get anthrax by eating infected meat that has not been properly cooked.
