Which network provides ongoing data for NAHSS?

• A. Public health department
• B. Veterinary diagnostic lab
• C. Academic research center
• D. Private practice

Answer: (B)

Ongoing surveillance relies on a steady stream of data from sources that regularly generate diagnostic results across many locations. Veterinary diagnostic laboratories fit this role for NAHSS because they routinely test animal samples from across the country, report both positive and negative results in a standardized way, and do so continuously. This creates a consistent, nationwide data feed that allows the system to establish baselines, monitor trends, and detect unusual disease activity quickly. Other sources like individual private practices, academic centers, or public health departments may contribute information, but they don’t provide the same comprehensive, real-time data stream across multiple species and regions that diagnostic labs do.
