Anthax Bacteria |
Eat well inspected, proper cooked meat.
Anthrax is a rare but serious illness caused by a spore-forming bacterium, Bacillus anthracis. Anthrax mainly affects livestock and wild game. Humans can become infected through direct or indirect contact with sick animals.
There's no evidence that anthrax is transmitted from person to person, but it's possible that anthrax skin lesions may be contagious through direct contact. Usually, anthrax bacteria enter the body through a wound in the skin. You can also become infected by eating contaminated meat or inhaling the spores.
Symptoms
There are four common routes of anthrax infection, each with different signs and symptoms. In most cases, symptoms develop within seven days of exposure to the bacteria. The one exception is inhalation anthrax. After exposure to inhalation anthrax, it may take weeks before symptoms appear.
Cutaneous anthrax
A cutaneous anthrax infection enters your body through a cut or other sore on your skin. It's by far the most common route the disease takes. It's also the mildest — with appropriate treatment, cutaneous anthrax is seldom fatal. Signs and symptoms of cutaneous anthrax include:
- A raised, itchy bump resembling an insect bite that quickly develops into a painless sore with a black center
- Swelling in the sore and nearby lymph glands
Gastrointestinal anthrax
This form of anthrax infection begins by eating undercooked meat from an infected animal. Signs and symptoms include:
- Nausea
- Vomiting
- Abdominal pain
- Headache
- Loss of appetite
- Fever
- Severe, bloody diarrhea in the later stages of the disease
- Sore throat and difficulty swallowing
- Swollen neck
Inhalation (pulmonary) anthrax
Inhalation anthrax develops when you breathe in anthrax spores. It's the most deadly way to contract the disease, and even with treatment, it is often fatal. Initial signs and symptoms of inhalation anthrax include:
- Flu-like symptoms, such as sore throat, mild fever, fatigue and muscle aches, which may last a few hours or days
- Mild chest discomfort
- Shortness of breath
- Nausea
- Coughing up blood
- Painful swallowing
As the disease progresses, you may experience:
- High fever
- Trouble breathing
- Shock
