Introduction To Public Health Practice Test

Bioterrorism can reach people through any route that can transfer an agent to a person or to a population. An agent might contaminate water supplies, leading to ingestion by many people; it can be released as an aerosol in the air, enabling inhalation exposure; it can contaminate foods, causing illness when consumed; and insects can act as vectors, spreading the agent from one host to another. Because all of these pathways are plausible for different agents, the comprehensive answer includes water, air, food, or insects. Understanding these routes helps public health planning for protection of water systems, air quality, food safety, and vector control.
