Which form of anthrax poses the greatest threat to population centers due to airborne transmission?

• A. Inhalational Anthrax
• B. Cutaneous Anthrax
• C. Gastrointestinal Anthrax
• D. Oropharyngeal Anthrax

Answer: (B)

Airborne spread is the deciding factor here. Inhalational anthrax occurs when spores are inhaled and can be carried by the air to many people in a population center, making it the form most capable of causing a mass exposure. This route allows a large number of people to be affected quickly, which is why it poses the greatest threat in crowded settings.

Cutaneous anthrax comes from direct skin contact with contaminated material and is typically localized, not distributed through the air. Gastrointestinal and oropharyngeal forms stem from ingestion or exposure to contaminated food or materials and are not driven by airborne dissemination in a population-wide scenario. So, inhalational anthrax is the form most associated with air release and mass exposure.
