Which statement is true regarding inhalational anthrax?

• A. It is usually fatal and presents with abrupt onset fever and nonproductive cough with biphasic progression.
• B. It is usually non-fatal.
• C. It presents with a skin lesion.
• D. It resolves without treatment.

Answer: (A)

Inhalational anthrax is a rapidly progressive and highly lethal form of the disease. When Bacillus anthracis spores are inhaled, they germinate in the lungs and trigger a v bad inflammatory and hemorrhagic process in the mediastinum, often with pleural involvement. The illness typically starts with nonspecific symptoms like fever, malaise, and a dry, nonproductive cough, but can abruptly worsen with high fever, chest discomfort, and respiratory distress. This biphasic pattern—an initial mild phase followed by a sudden dramatic deterioration—is classic. Because progression can be so fast, without prompt, aggressive treatment the outcome is commonly fatal. The statement reflects this dangerous, rapid course and the respiratory-pulmonary presentation. It’s not consistent with inhalational anthrax to be non-fatal, to have a skin lesion as the primary feature, or to resolve without treatment.
