Anthrax is a serious infectious disease caused by the bacterium Bacillus anthracis. This bacterium produces spores that can survive for decades in soil, animal products, and contaminated environments. Anthrax primarily affects grazing animals like cattle, sheep, and goats, but humans can also contract the disease through direct contact with infected animals, inhalation of spores, or consumption of contaminated meat. Though rare in many developed countries, anthrax remains a public health concern in regions with poor veterinary control and has also been recognized as a potential bioterrorism threat due to its ability to be weaponized. Anthrax infections can manifest in four forms: cutaneous (skin), inhalation (lungs), gastrointestinal (digestive system), and injection (associated with drug use). Each form varies in severity, but all require prompt medical intervention to prevent fatal complications. Understanding anthrax’s transmission, symptoms, prevention, and treatment is crucial for managing outbreaks and minimizing risks to both humans and animals. Anthrax infections can manifest in four forms: cutaneous (skin), inhalation (lungs), gastrointestinal (digestive system), and injection (associated with drug use). Each form varies in severity, but all require prompt medical intervention to prevent fatal complications. The bacterium Bacillus anthracis produces deadly toxins that attack the body’s cells, leading to severe inflammation, tissue damage, and systemic infection [1,2]. The spores can be found in the soil for years, making anthrax a persistent threat to livestock and humans who come into contact with contaminated environments. Outbreaks often occur in agricultural regions where proper vaccination and hygiene practices are not maintained. Anthrax has also been used as a biological weapon, highlighting its potential danger beyond natural outbreaks. Governments and health organizations actively monitor and prepare for possible anthrax-related bioterrorism threats. Understanding anthrax’s transmission, symptoms, prevention, and treatment is crucial for managing outbreaks and minimizing risks to both humans and animals. With appropriate medical interventions and public health measures, anthrax infections can be prevented and controlled effectively, reducing their impact on public health and global security [3,4].

Causes and Transmission

Anthrax is caused by the Bacillus anthracis bacterium, which produces spores that can remain dormant in the environment for long periods. These spores become active when they enter a suitable host, releasing toxins that cause severe illness. The main ways anthrax spreads include:

Direct Contact with Infected Animals: People handling infected livestock, animal hides, or wool may contract anthrax through cuts or abrasions in the skin, leading to cutaneous anthrax [5].

Inhalation of Spores: Breathing in anthrax spores from contaminated environments (such as industrial facilities processing animal products) can lead to inhalation anthrax, the deadliest form of the disease.

Consumption of Contaminated Meat: Eating undercooked or contaminated meat from infected animals can cause gastrointestinal anthrax [6].

Injection of Contaminated Drugs: Drug users who inject heroin or other contaminated substances may develop injection anthrax, a rare but severe form of the disease.

Types of Anthrax and Symptoms

Anthrax manifests in different forms, each with distinct symptoms:

Cutaneous Anthrax:

Most common form, accounting for about 95% of cases.

Occurs when spores enter the skin through cuts or wounds [7].

Symptoms include red, swollen lesions that develop into painless black sores (eschar).

Without treatment, infection can spread, leading to severe complications.

Inhalation Anthrax:

The most deadly form, occurring when spores are inhaled.

Symptoms begin with flu-like signs, including fever, cough, and fatigue.

As the infection progresses, severe respiratory distress, shock, and death can occur [8].

Fatality rates are high without early treatment.

Gastrointestinal Anthrax:

Results from consuming contaminated meat.

Symptoms include severe abdominal pain, nausea, vomiting, diarrhea (sometimes bloody), and fever.

Can cause sepsis and organ failure if untreated.

Injection Anthrax:

A rare form seen in intravenous drug users.

Causes severe soft tissue infections, swelling, and necrosis at the injection site [9].

Can spread to the bloodstream, leading to systemic complications.

Diagnosis of Anthrax

Diagnosing anthrax involves:

Physical Examination: Checking for symptoms such as skin lesions, breathing difficulties, or gastrointestinal distress.

Blood Tests: Detecting anthrax bacteria in the bloodstream.

Chest X-rays or CT Scans: Identifying inhalation anthrax by detecting lung abnormalities [10].

Skin Lesion Swabs: Testing skin sores for Bacillus anthracis.

Stool Samples: Used for diagnosing gastrointestinal anthrax.

Treatment and Management

Anthrax is treatable with early medical intervention. The primary treatment options include:

Antibiotics:

Ciprofloxacin, doxycycline, and penicillin are commonly used to kill Bacillus anthracis.

Antibiotics are most effective when administered early in the infection.

Antitoxins:

Used to neutralize anthrax toxins in severe cases.

Often combined with antibiotics for better outcomes.

Supportive Care:

Inhalation anthrax patients may require intensive care, oxygen therapy, and ventilator support.

Fluids and medications may be needed to manage symptoms and complications.

Surgical Intervention:

In cases of injection anthrax, surgical removal of infected tissue may be necessary.

Prevention Strategies

Preventing anthrax infections involves public health measures, vaccination, and safe handling of animals and animal products. Key prevention methods include:

Anthrax Vaccination:

The anthrax vaccine is recommended for high-risk individuals, such as military personnel, laboratory workers, and people handling potentially infected animals.

Not widely available for the general public.

Protective Measures for Livestock:

Regular vaccination of livestock in high-risk areas.

Proper disposal of infected animal carcasses to prevent soil contamination.

Safe Handling of Animal Products:

Workers in industries dealing with animal hides, wool, and meat should wear protective clothing and use sterilization techniques.

Avoiding Contaminated Meat:

Proper cooking of meat to kill any potential spores.

Ensuring livestock are free from anthrax before processing.

Bioterrorism Preparedness:

Governments and health agencies monitor potential bioterrorism threats involving anthrax.

Emergency response plans include rapid diagnosis, treatment stockpiling, and public awareness campaigns.

Conclusion

Anthrax remains a dangerous infectious disease with significant health and security implications. While rare in many parts of the world, it continues to pose a risk in areas with inadequate animal vaccination programs and poor public health infrastructure. Understanding the modes of transmission, symptoms, and treatment options can help prevent outbreaks and improve response strategies. Public awareness, improved medical interventions, and coordinated global efforts are essential in controlling anthrax and reducing its impact on human and animal populations.
