How does ADT improve disease control?

• A. It reduces the need for surveillance entirely.
• B. It automates vaccine production.
• C. It improves laboratory testing speed.
• D. It enables rapid identification and tracing of animal movements to limit outbreaks.

Answer: (D)

Tracking animal movements is central to effective disease control. Animal Disease Traceability (ADT) collects data on where animals have moved—births, transfers, sales—and makes it possible for investigators to reconstruct exposure pathways quickly when a disease is detected. In an outbreak, rapid identification of the movements linked to an infected premise lets authorities implement targeted movement restrictions, quickly identify other at‑risk herds, and guide focused surveillance and testing. This rapid tracing interrupts transmission chains and helps limit outbreak size and duration. ADT does not replace surveillance or lab testing, nor does it automate vaccine production or directly speed up laboratory processing. The main advantage is enabling fast identification and tracing of animal movements to contain and limit outbreaks.
