• B. Directly from people.
• C. Medical journals and newspapers.
• D. Hands-on experience and through the grapevine.

Answer: (B)

Direct information from people on the ground—healthcare workers, patients, and community informants—is the primary way we gather medical intelligence because it provides timely, firsthand observations of what is actually happening. Frontline reports capture real-world symptoms, unusual clusters, and evolving patterns as they occur, which allows public health teams to detect threats early and respond quickly. This on-the-ground data is typically collected through interviews, field investigations, case reports, surveillance forms, and hotlines, all of which translate daily experiences into actionable intelligence.

Other sources have limitations. Espionage raises ethical and legal concerns and isn’t the standard approach for public health intelligence. Medical journals and newspapers are valuable for background and context but often lag behind current events and may miss rapidly changing situations. Relying on informal rumor or “grapevine” information is unreliable without verification and can mislead responses. Hands-on experience is important but needs to be complemented by systematic, real-time reports from people to form a robust intelligence picture.
