The form of anthrax that health authorities are most concerned about is inhalational anthrax, which occurs when a person breathes in anthrax spores. Anthrax vaccine is not available to the general public. Inhalational anthrax is not contagious, so it does not spread from person to person. Healthy people who come into contact with persons sick with inhalational anthrax cannot acquire the disease. It can be treated with antibiotics. In the event of an outbreak, there are plans in place to provide antibiotics to those exposed to the disease. Should you have any specific concerns, you should talk with your physician.
