Human anthrax in India: urgent need for effective prevention

Area of Science:

• Veterinary Medicine
• Infectious Diseases
• Public Health

Background:

• Anthrax, a zoonotic disease caused by Bacillus anthracis, presents a growing public health concern globally and in India.
• The Union Territory of Pondicherry has observed a significant rise in anthrax cases, with 34 human cases reported and an increasing trend noted in both veterinary and human practices.

Purpose of the Study:

• To highlight the increasing incidence of anthrax in Pondicherry.
• To discuss the clinical presentation, prognosis, and diagnostic findings of anthrax, particularly the meningitic and cutaneous forms.
• To emphasize the importance of control measures for anthrax.

Main Methods:

• Review of reported human anthrax cases in Pondicherry.
• Clinical observation and diagnosis of anthrax, including cerebrospinal fluid (CSF) analysis for meningitis.
• Analysis of patient history, particularly occupational exposure to animals.

Main Results:

• A notable increase in anthrax cases in Pondicherry between 1999-2000, with agricultural laborers being most affected.
• Meningitic anthrax demonstrated a poor prognosis, with fatalities despite high-dose penicillin treatment, confirmed by bacilli in CSF.
• Cutaneous anthrax exhibited a benign course and responded well to penicillin.

Conclusions:

• Increased awareness among clinicians and mandatory case reporting are vital for reducing anthrax morbidity and mortality.
• Public education and effective animal immunization programs are essential control strategies for anthrax.
• Prompt diagnosis and appropriate treatment, considering the form of anthrax, are critical for patient outcomes.
