Anthrax is an infection caused by bacteria. It can be life-threatening.
There are three forms of human anthrax, depending on where anthrax enter the body:
- Inhaled—from breathing airborne spores into the lungs
- Cutaneous (or skin)—due to spores entering a cut or break in the skin (most common)
- 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.
Anthrax Can Enter the Body Through the Lungs
