Syndromic Surveillance for New Users

What to know

CDC wants to build a state-of-the art public health workforce. To work with syndromic data, you’ll need to know what these data represent so your interpretation is accurate. You’ll also need to understand the strengths and limitations of syndromic surveillance. NSSP offers many avenues of support to acquire next-generation skills.

First steps for new users

We recommend that all new users get connected with the syndromic surveillance community. Collaboration is crucial to help us eliminate siloes and aid decision-making as we work together to protect our communities through improved readiness and response to health threats.

Site administrators work with NSSP to provide data access

The BioSense Platform is a cloud-based early detection and monitoring system that integrates public health data from many sources. To request access to the platform and its tools, reach out to the site administrator at your state or local health department. They serve as liaisons between users and NSSP. Site administrators can also answer questions and provide resources.
