A nurse is investigating a potential bioterrorism attack. What evidence would a nurse find if a bioterrorism attack occurred?

A. Many cases of influenza: This is a common seasonal illness and wouldn’t typically indicate bioterrorism unless highly unusual in pattern or severity. B. A case of cholera in a local politician following a trip to India: This is likely travel-related and not a suspicious cluster. C. Dengue fever in a group of students who just returned from a mission trip: This too is expected from travel exposure, not domestic bioterrorism. D. An unusual illness in a population: Bioterrorism often involves the sudden appearance of an unexpected illness, especially if uncommon for the region or population.
