Which category includes emerging pathogens that could be engineered for mass dissemination in the future?

• A. Category A
• B. Category B
• C. Category D
• D. Category C

Answer: (D)

Understanding how agents are grouped by threat level helps explain why this description fits the emerging-pathogen category. The phrase “emerging pathogens that could be engineered for mass dissemination in the future” describes organisms that aren’t yet high-profile threats but have potential for future misuse as they emerge and gain capabilities. That kind of risk—unknown, evolving agents with the potential to be engineered for rapid spread—belongs to the category designated for emerging pathogens with dissemination potential in the future. It’s distinct from the highest-threat group, which covers agents already known to spread easily and cause severe illness, and from the category of agents that are moderately easy to disseminate. The remaining label isn’t part of the standard three-category framework. So the category that fits this description is the one for emerging pathogens with future dissemination potential.
