New to Syndromic Surveillance?
Syndromic data are captured in nearly real time, which is particularly helpful for assessing the public’s health at any given time or for monitoring specific conditions (e.g., asthma, influenza-like illness). Syndromic surveillance can help you recognize an emerging environmental hazard that affects public health (such as respiratory problems from a chemical spill) and can also help you identify illness before diagnoses are confirmed and reported.
Because of the immediacy of syndromic data, you’ll need a strong understanding of what these data represent so that your interpretation is accurate. You’ll also need to understand the strengths and limitations of syndromic surveillance before integrating it fully into daily practice.
The resources listed below will help you gain a better understanding of syndromic surveillance.
These job aids bring together some of the “best of” resources developed by NSSP and the community:
- Query Development: Community and Technical Resources takes you step-by-step through the collaborative process of developing and testing queries (syndrome definitions).
- The Ultimate Guide for Site Administrators suggests ways to connect with peers, exchange technical solutions quickly, and points to all things NSSP.

- NSSP and How We Conduct Syndromic Surveillance

We recommend that anyone new to syndromic surveillance join NSSP’s long-established Community of Practice (CoP). The NSSP CoP is a thriving community of people passionate about public health and syndromic surveillance.
Members range from epidemiologists conducting analyses for the first time in a real-world public health environment to experts in public health surveillance. To jump start your learning experience, take advantage of the NSSP CoP’s expert presentations and opportunities to collaborate with leaders in analytics, surveillance, informatics, and more.
Visit the NSSP CoP website, check out the New Member Orientation recording and call calendar, and peruse the extensive Knowledge Repository for resources. A high-level peek at all NSSP resources can be found here: Syndromic Surveillance Training Resources.
