Anthrax Disease: Causes, Signs, Symptoms, and Treatment


Nigeria has witnessed a series of alarming anthrax outbreaks that have wreaked havoc on livestock across several states. The dire need for awareness, prevention, and swift treatment has never been more pressing. Anthrax, a bacterial disease that affects both animals and humans, has cast a shadow of concern over the nation’s agricultural and public health landscape. In this article we’ll shed light on the causes, signs, symptoms, and treatment of anthrax, equipping readers with vital information to combat its spread and impact.

An Urgent Call for Awareness of the Disease

With anthrax outbreaks making headlines and livestock falling victim, the urgency of understanding this disease cannot be overstated. Livestock farming, an integral part of Nigeria’s economy and food supply chain, faces threats from anthrax that could have far-reaching consequences. 

Moreover, anthrax is a zoonotic disease, meaning it can be transmitted from animals to humans. This makes it essential for everyone to grasp the basics of anthrax, its potential dangers, and the measures to prevent its spread.

Causes of Anthrax and Risk Factors

Anthrax is caused by the bacterium Bacillus anthracis, which forms spores that can survive in the environment for extended periods. These spores are highly resilient and can remain dormant until they come into contact with a suitable host. The bacterium primarily affects herbivores such as cattle, sheep, and goats, but it can also impact other animals and humans.

The spores of Bacillus anthracis can be found in soil and can be ingested by animals during grazing. In some cases, natural disasters like flooding or drought, may bring spores to the surface, increasing the risk of exposure. This could explain the recent spikes in outbreaks in various states, as the disease outbreak began in the thick of the rainy season. 

Additionally, poor animal husbandry practices, lack of vaccination, and improper disposal of animal remains can contribute to its spread.

Signs and Symptoms of Anthrax

Recognizing the signs and symptoms of the disease is pivotal in early detection and containment. In animals, it can present in different forms:

  1. Cutaneous Anthrax: This form affects the skin and is marked by the development of ulcers, swelling, and black scabs. It is usually not fatal if treated promptly.
  2. Pulmonary Anthrax: Inhalation of anthrax spores can lead to this severe form, characterized by fever, difficulty breathing, and shock. It is often fatal if not treated early.
  3. Gastrointestinal Anthrax: Ingesting spores through contaminated feed or water can result in gastrointestinal anthrax, causing symptoms like vomiting, abdominal pain, and diarrhea.

In humans, symptoms can vary depending on the mode of exposure. For Cutaneous Anthrax, Skin lesions may occur which could evolve into ulcers with a black center. However in the case of Pulmonary Anthrax, patients may suffer fever, cough, difficulty breathing, and flu-like symptoms that rapidly worsen. Gastrointestinal Anthrax is usually characterized by nausea, vomiting, abdominal pain, and diarrhea.

Immediate medical attention is crucial if any of these symptoms arise, particularly if there is a history of exposure to livestock or contaminated materials.

Anthrax Prevention and Treatment

Preventing the disease is not a one-size fits all situation. It usually involves a multi-pronged approach which may include:

  1. Vaccination: Vaccinating livestock against anthrax is a cornerstone of prevention. Regular vaccination, particularly in high-risk areas, can substantially reduce the likelihood of outbreaks.
  2. Hygiene Practices: Proper disposal of animal remains and decontamination of areas where livestock graze can limit the spores’ spread.
  3. Quarantine and Reporting: Suspected cases should be reported to veterinary authorities immediately. Quarantining affected animals prevents the disease from spreading further.
  4. Personal Protection: Farmers, veterinarians, and those who handle livestock should use protective gear to minimize direct contact with potentially contaminated materials.
  5. Cooking: Thoroughly cooking meat before consumption eliminates the risk of disease transmission.

Timely Treatment of the Disease

Timely treatment is essential to halt the progression of the disease. In animals, antibiotics such as penicillin and tetracycline can be effective when administered promptly. However, prevention through vaccination remains the most effective strategy.

In humans, the treatment plan depends on the severity and mode of exposure. Early intervention with antibiotics, such as ciprofloxacin, can improve survival rates. Patients with pulmonary anthrax may require more intensive care, including respiratory support.


As Nigeria grapples with the outbreaks, the power of knowledge cannot be underestimated. Understanding the causes, signs, symptoms, and treatment options is a crucial step toward minimizing the impact of this disease on livestock, humans, and the economy. By practicing vigilant animal husbandry, adopting preventive measures, and seeking medical attention at the first sign of illness, we can collectively combat anthrax and safeguard the well-being of our communities.
