anthrax disease causes symptoms and treatment
Anthrax Disease - Causes, Symptoms and Treatment
In recent years, the very infamous word, 'Anthrax letters' came to light, when terrorists used anthrax spores in mails to spread the disease. These letters were directed to few US media houses and senators claiming innocent lives post September 11 attacks. Let's get to know more about this fatal disease.
- Through direct contact with the skin or tissues of an infected animal/human to a healthy animal/human (there have been no known cases of this disease-spreading from one person to another)
- By inhaling the air in which bacterium of this disease is active
- Cutaneous Anthrax: This type of anthrax spreads through direct contact with the skin of an infected animal or human.
- Gastrointestinal Anthrax: This type of anthrax is caused by consumption of infected food/meat.
- Pulmonary Anthrax: This is also known as respiratory, pneumonic or inhalational anthrax. It spreads through respiratory tract of the host when a person inhales the spores. The resulting infection is highly lethal and the mortality rates are almost 100%. This type of infection takes very less time to attack and kill the host.
- Infection of this type of anthrax in humans is characterized by boil-like skin lesions that start with skin bumps and form ulcers with black, painless patches/eschars.
- The ulcers start as small, black patches on skin (like itchy and irritating lesions).
- The area on the skin from where the spores penetrated the skin start showing changes from day 2.
- There is an uneasy feeling due to the toxin excreted by the bacterium.
- Vomiting of blood
- Acute inflammation of the intestinal tract
- Severe diarrhea
- Gastrointestinal difficulty
- Loss of appetite
- Collapse of intestinal tract
- Lesions in intestinal area as well as in mouth and throat
- Uneasy feeling due to the toxin excreted by the bacterium
- This type of anthrax shows all the flu-like and common cold symptoms.
- Problems related to the respiratory system occur.
- Within a couple of days, the patient's respiratory system collapses completely.
- Test of infected skin/skin sores: A small sample of the infected skin tissue or fluids from the infected skin sores can be subjected to biopsy in labs for the detection of anthrax bacteria.
- Test of blood samples: Blood samples of the patient can be checked for anthrax bacteria.
- CT scans and Chest X-Ray: X- Ray reports of the chest and CT scan help detect anthrax spores inhaled by the patient.
- Spinal Tap: It is done to confirm anthrax meningitis wherein fluid samples are extracted from the spinal canal of the patient and studied.
- Endoscopy: An endoscopy of the intestine and throat can be done in case of intestinal anthrax. Also, in certain cases, stool samples of the patient are taken to detect the presence of anthrax.
- High doses of antibiotics like ciprofloxacin, penicillin, tetracycline, etc. are used in case of skin infections. The treatment duration in case of cutaneous anthrax infection is 7 to 10 days.
- In case of inhalational anthrax infection, a combination of powerful antibiotics are used to treat the disease. The length of the treatment stretches to 60 days.
