Anthrax occurs naturally in the soil where it can last for many years. Anthrax is a disease of animals or people caused by a bacterium, Bacillus anthracis. Anthrax occurs naturally in the soil where it can last for many years. The disease is most often found in cattle, sheep, goats, camels, antelopes, and other herbivores, but humans can also get this disease if they are exposed to infected animals or their tissues.
Anthrax can infect humans in three different ways. It can cause a skin infection if it gets into a cut or sore; if ingested, it can cause an abdominal infection; if inhaled, it can cause a lung infection. The last form is the most serious. There are a few cases (less than 10) of human anthrax skin infections in the United States every year among people who work closely with animals. These cases are almost never fatal.
The possibility of transmission of anthrax from animal to person or person to person is very low. However, anthrax spores are very hardy and can be engineered so that they easily disperse in the air. This so-called “weaponized” anthrax is the kind that was used in the series of postal attacks in October 2001. This form of anthrax is specially treated so that it does not “cake” and will readily disperse into the air if disturbed; however, significant technical expertise is required to do this.
Anthrax is one of several disease-causing agents that many experts consider useful for biological warfare.
Good Web sites for the public
1. FAQ’s about anthrax
An excellent site with a question and answer format. The site has three pages that give general information, technical information, and “additional” information.

2. Tutorial on Anthrax
A self-paced tutorial designed for the general public and accompanied by audio. It may run a little slow on a computer connected to the Internet with a modem. It is an engaging and informative introduction to the subject of anthrax as a disease and as a weapon.
