When a person is exposed to anthrax, the most common form of the disease is cutaneous anthrax, which is an infection of the skin. This form of anthrax is caused by the bacterium Bacillus anthracis.
Once the infection is contracted, the bacteria will enter the body through a break in the skin, such as a cut or an insect bite. The bacteria will then multiply and spread through the lymphatic system, eventually reaching the lymph nodes and bloodstream.
Once the bacteria is in the blood, it can cause a variety of physical symptoms, such as fever, chills, headaches, muscle aches, and fatigue. The infected person may also develop a raised, itchy rash on the skin at the site of infection that may look like a small blister. If the infection is left untreated, the rash may begin to ooze and turn black, and the person may develop swelling and pain in the affected area.
In more serious cases, the infection may spread to the lungs, causing severe breathing problems, or to the brain, causing meningitis. If the infection is not treated with antibiotics, the person may experience organ failure, shock, and death.
Therefore, it is important to seek medical attention as soon as possible if you think you have been exposed to anthrax. Early diagnosis and treatment can help prevent serious health complications.
