Characteristics of
Suspicious Packages and Letters

1. Anthrax organisms can cause infection in the skin,
gastrointestinal system, or the lungs. To do, so the organism must be rubbed into abraded skin, swallowed, or inhaled as a fine,
aerosolized mist. Disease can be prevented after exposure to the anthrax spores by early
treatment with the appropriate antibiotics. Anthrax is not spread from one person to
another person.
