Anthrax (炭疽) is a naturally occurring disease of plant-eating animals caused by the anthrax bacillus (杆菌)．It is an illness which has been recognized since ancient times．Anthrax was common essentially in all areas where livestock (=animals kept on a farm, such as sheep and cattle) are raised．Intensive livestock immunization (免疫) programs have greatly reduced the occurrence of the disease among both animals and humans in much of the world．However, outbreaks occurred during the mid-1990’s in Haiti and the former Soviet Union．

Anthrax bacteria are named for the Greek word for coal-anthrax, because they cause coal-black injury when they infect the skin．Anthrax spores (孢子) can remain viable for several decades (a period of ten years) under suitable environmental conditions; thus, absence of cases does not equate to absence of risk．Humans can contract (=to get to have an illness) anthrax in three ways: through cuts or breaks in the skin resulting from contact with an infected animal, from breathing anthrax sores or eating infected meat．

One day in September, 2001, a 7-month-old son off an ABC producer in Manhattan spent time at the network offices．He developed a rash, and was hospitalized with an unknown illness soon after the visit．He was later diagnosed (诊断) anthrax．This was the beginning of the anthrax scare (=a sudden feeling of fear) created by terrorists  throughout the USA and the rest of the world．
