If there is one disease that is rare but should not be ignored, it is anthrax as it can be quite severe. It is caused by a spore-forming bacterium known as Bacillus anthracis which commonly infects livestock and wildlife. Humans can, however, develop anthrax infection through direct or indirect contact with animals that are infected, making awareness crucial.
Anthrax disease takes several forms – cutaneous (infecting the skin), gastrointestinal, and inhalation – all exhibiting different signs. Even though anthrax is rare, its potential to be contagious and that there is a possibility of it being used in bioterrorism establishes that it is necessary to identify and treat the affected individuals as soon as possible.
Luckily, due to progress in medicine, there is fast treatment through antibiotics and other therapies, which can be life-saving.
Understanding how anthrax is diagnosed, its symptoms and its causes are not just informative but can empower you to protect yourself and those around you.
Anthrax is a relatively rare but serious infectious disease caused by ring bacteria known as Bacillus anthracis. These bacteria exist in a dormant state in the soil, which mainly infects grazing animals like cows, sheep, and goats.
So, what is anthrax in humans? It is an infectious disease that is non-contagious but can be fatal if not treated appropriately. It poses a higher risk for people dealing with infected animals and laboratory workers involved in the study of the causative bacterium. People who come into contact with anthrax during certain bioterrorism acts can also get infected.
Even though anthrax is not transmitted from one person to another, early intervention is important because deaths can be avoided with the help of antibiotics or immunization.
Anthrax is an infectious disease caused by a bacterium, Bacillus anthracis, which has resilient spores that can persist in soil for many years. Susceptible hosts like cattle and sheep and wild animals like deer unknowingly ingest or breathe in these dormant spores while grazing, which later on triggers the infection cycle in them.
Once the anthrax spores gain entry into the body, they come in contact with body fluids get activated and start multiplying. This results in the development of toxins that disseminate throughout the organism’s body, and can elicit severe life-threatening responses.
In humans, anthrax can also be affected by handling animals with the disease, inhalation of spores, or consumption of contaminated meat.
With Bacillus anthracis having this kind of resistance it remains a real threat to environments where animals are exposed to the contaminated grazing lands. The fact that these spores can survive for long without causing anthrax elucidates the need for preventive strategies, especially for the high-risk zones or businesses relating to livestock and animal products.
The types of anthrax are defined by how the bacteria enter the body, each posing unique risks and symptoms. Here’s an overview of the main types:
Cutaneous anthrax is composed of Bacillus anthracis bacteria. It is the most common form of disease that results from the invasion of the bacterium through the skin and is associably the least serious form of the disease.
People who are mainly engaged in high-risk activities include veterinarians and those who come into contact with animals’ wool, hide, or hair. As a result, prompt treatment will most often lead to a full recovery.
This kind emerges when people eat raw or undercooked meat from infected animals. These bacteria invade the esophagus, throat, stomach, and intestines. Hence, patients complain of severe gastrointestinal problems.
Inhalation anthrax, or “woolsorter’s disease, is, on the other hand, the most dangerous type, which can be contracted when a person breathes in anthrax spores. It causes a disease if untreated, that produces significant respiratory distress and death in most cases. People working in places such as wool processing mills, tanneries as well as slaughterhouses encounter much higher risks.
Injection anthrax affects individuals who inject drugs like heroin. This rare form results in deep infections in muscles or under the skin.
Anthrax symptoms in humans vary depending on how the infection occurs. There are four primary types of anthrax—cutaneous, gastrointestinal, inhalation, and injection—each presenting distinct signs. Symptoms often appear within six days of exposure, but inhalation anthrax may take weeks to manifest.
Cutaneous anthrax, the most common and mildest form, enters through a cut or sore on the skin. Symptoms include:
Gastrointestinal anthrax occurs from eating undercooked meat from infected animals. It affects the digestive tract, causing:
The deadliest form, inhalation anthrax, results from breathing in spores. Early symptoms mimic the flu, including:
Reported primarily in Europe, injection anthrax arises from injecting illegal drugs. Symptoms include:
Recognizing anthrax symptoms early can save lives. Timely medical attention and treatment are critical for all forms of this infection.
Anthrax disease can lead to severe and life-threatening complications if left untreated. The most serious include sepsis, where the body’s response to infection causes multiple organ damage, and hemorrhagic meningitis, a deadly inflammation of the brain and spinal cord that results in massive bleeding
Complications vary depending on the type of anthrax:
Diagnosing anthrax involves a combination of clinical evaluation, imaging, and laboratory tests. Healthcare providers begin by assessing symptoms, exposure history, and risk factors. Based on these findings, they may recommend specific tests to confirm the presence of Bacillus anthracis.
The most common method is B. anthracis detection in blood, biopsy from the skin lesions, and B. anthracis detection in stool. These tests help identify the infection and determine the type of anthrax affecting the patient.
Chest radiographs and CT scans are routinely done to assess the presence of effusions and/or mediastinal enlargement which is seen in inhalational anthrax. Endoscopy may be performed to evaluate the esophagus or the intestines in the case of suspected intestinal anthrax.
In most cases of complicated diseases, cerebrospinal fluid can be sampled by using a spinal tap (lumbar puncture). This test is important when there is a suspicion of complications caused due to anthrax, such as hemorrhagic meningitis.
Timely anthrax treatment is crucial to prevent serious complications and save lives. Most forms of anthrax respond well to medical interventions when detected early. If you suspect exposure, contacting a healthcare provider immediately is essential to begin treatment promptly.
Preventing anthrax involves a combination of vaccination, responsible practices, and avoiding potential sources of infection. The Centers for Disease Control and Prevention (CDC) outlines effective strategies to minimize the risk of contracting this serious disease.
The anthrax vaccine is a critical preventive measure for individuals in high-risk professions, including military personnel, livestock handlers, veterinarians, and researchers working with Bacillus anthracis.
This vaccine is 90% effective at preventing infection. It involves a series of five doses over 18 months, followed by an annual booster. The vaccine can also help stop infection if administered shortly after exposure to anthrax spores.
After exposure, a 60-day course of antibiotics such as ciprofloxacin, doxycycline, or levofloxacin is recommended. In some cases, monoclonal antibodies like raxibacumab and obiltoxaximab may be used to further protect against infection.
Travelers to anthrax-prone regions should avoid eating raw or undercooked meat, handling animal hides or hair, and making contact with animals. These simple steps can significantly reduce the risk of exposure.
Anthrax is a rare but serious disease that can be effectively managed and prevented with timely interventions. By understanding its causes, symptoms, and treatment options, as well as adhering to preventive measures like vaccination and safe practices, the risk of infection can be significantly reduced.
