Anthrax

Definition

Anthrax is an infection, which can be life threatening.There are 3 forms of human anthrax, depending on where anthrax enters the body:
  • Cutaneous (or skin)—due to spores entering a cut or break in the skin (most common)
  • Inhaled—from breathing airborne spores into the lungs
  • Gastrointestinal—from ingesting spores in raw or undercooked food
Once anthrax is in the body, it multiplies and releases toxins. The toxins cause swelling, bleeding, and tissue death. All forms of anthrax can cause death but inhaled anthrax has a much higher mortality rate once symptoms develop.
