What is anthrax?
Anthrax is a disease caused by bacteria that has a short course of possibly severe illness. The bacterium, Bacillus anthracis, most commonly occurs in warm-blooded animals, but can infect humans.
Symptoms of human infection by inhaling (breathing in) the bacteria:
- usually occur within 7 days of being exposed to the bacteria
- initial symptoms may resemble a severe cold or influenza
- after several days, a person may have severe breathing problems and may go into shock
- an X-ray may show a widened area between the ribs
Symptoms of human infection by swallowing the bacteria:
- the intestinal tract becomes inflamed
- people feel nauseated (sick to their stomachs)
- there may be loss of appetite
- there may be vomiting and fever
- these symptoms are followed by abdominal pain, vomiting blood, and bloody diarrhea
Symptoms of human infection by skin contact (cutaneous exposure):
- severe itching followed by a lesion (sore)
- lesion becomes elevated and rounded (papular), then blister-like (vesicular), then in 2-6 days becomes a depressed black scab (eschar), surrounded by swelling
- pain is unusual
- if untreated, may cause septicemia
Is there any anthrax vaccine available to prevent me from getting the disease?
The anthrax vaccine is not currently available to the general public. The vaccine is only available to the military because of the risk they may encounter overseas. Even in light of the current situation, the risk of exposure to anthrax by the general public is considered to be low. Exposure to anthrax can be treated with early interventions. Anthrax does not spread from person to person. If a person is exposed to anthrax, plans are in place to ensure that appropriate interventions reach affected communities.
Should I be tested for anthrax?
If you believe that you have been exposed to anthrax, you should contact the local law enforcement in your community. Local law enforcement will determine if an exposure has occurred. They may call the FBI to assist in making the assessment of exposure. If a decision is made that there is a credible threat of exposure, environmental samples will be collected for testing to see if anthrax is present. If anthrax is found to be present, you will be tested. Without laboratory evidence of an exposure to the bacteria, testing is not recommended.
The need for testing will be determined after a credible threat of anthrax exposure has been made in our community.
What is the treatment for anthrax infection?
The diagnosis for anthrax infection is done by finding Bacillus anthracis bacteria in a person's blood, skin lesions, or respiratory secretions, or by measuring specific antibodies in the blood.
Anthrax is treated with antibiotics. Antibiotics must be given early - any delay, even hours, may lessen chances for survival. For those treated with antibiotics, the risk of recurrence is high for 60 days.
You should not purchase or take antibiotics, especially penicillin or ciprofloxacin, in order to prevent getting anthrax disease without knowing if you have been exposed. Using these antibiotics unnecessarily may promote resistance when antibiotics are really needed.
If I think I have been exposed to anthrax, (I received a suspicious letter) what should I do?
If you receive a letter you think is suspicious, please follow the Michigan Department of Community Health guidelines, found at http://www.mdch.state.mi.us/anthrax/anthrax.htm contact your local law enforcement for a threat assessment. Local law enforcement will determine if there is a risk of exposure.
