Is anthrax contagious?

Inhalation anthrax (caused by breathing in the spores) and gastrointestinal anthrax (caused by ingesting spores or bacteria) are not spread from person to person. Even if you develop symptoms of inhalation anthrax or gastrointestinal anthrax, you are not contagious to other persons, regardless of whether you are taking antibiotics or not. Cutaneous anthrax does not usually develop into a serious infection if it is treated with antibiotics. Discharge from the skin sore(s) caused by cutaneous anthrax can contain anthrax spores that can be controlled by proper bandaging.
