Anthrax: A Zoonotic Disease More Severe Than You Might Think

Many people may not be familiar with the term "Anthrax," as it is not a disease that occurs frequently. However, when it does, it can be extremely serious. Recently, on April 30th, a fatal case was reported in Don Tan District, Mukdahan Province, Thailand.

 Initial investigations suggest that the deceased was infected while butchering cattle and distributing the meat to villagers. Currently, two more cases have been confirmed, and over 600 individuals are under observation due to potential exposure.


 What is Anthrax?
Anthraxalso known in some regions as Kali diseaseis caused by a bacterium called Bacillus anthracis. This pathogen is naturally found in soil, water, or plants and is remarkably resilient. It can survive in extreme environmental conditions, both hot and cold, by forming highly durable spores that can remain viable for extended periods.


 How is Anthrax Transmitted?
Anthrax is a zoonotic disease, meaning it can be transmitted from animals to humansparticularly from herbivorous animals such as cattle, buffalo, goats, and sheep. It can spread through three main routes:

 Cutaneous (via skin contact): By handling infected animals or their carcasses
Inhalation: By breathing in spores
Ingestion: By consuming undercooked or contaminated meat
Alarmingly, anthrax spores can withstand temperatures of up to 140°C for as long as three hours. Therefore, undercooked or improperly prepared meat may not be sufficient to eliminate the bacteria.


 Symptoms Vary by Route of Entry:
Inhalation exposure:
Symptoms include fever, chills, chest tightness, cough, difficulty breathing, headache, nausea, excessive sweating, fatigue, and dizziness.

 Cutaneous exposure:
Usually starts as an itchy red bump that turns into a blister, followed by a swollen ulcer with a black center. Lesions often appear on the face, neck, or arms.

 Gastrointestinal exposure:
Symptoms include fever, chills, sore throat, swollen neck, enlarged lymph nodes, nausea, vomiting (sometimes with blood), severe diarrhea, abdominal pain, and possible unconsciousness.

 How is Anthrax Treated?
Anthrax is treatable if diagnosed and managed promptly. Standard treatment includes:

 Antibiotics: Such as penicillin, doxycycline, or fluoroquinolones
In severe cases: Additional antitoxins such as clindamycin or linezolid may be administered
Close monitoring: Is crucial, as symptoms can progress rapidly in some patients

 How Can We Prevent Anthrax?
Avoid contact with sick animals or animals of unknown origin
Do not consume raw or undercooked meat or unpasteurized milk
Use gloves and protective gear when handling animal carcasses
If you experience unusual symptoms after handling animals or consuming unusual meats, seek medical attention immediately
