CDC's National Environmental Public Health Tracking Network (EPHTN) is a national system that integrates data about environmental hazards and exposures with data about diseases that may be linked to the environment. In this way, existing environmental hazard, exposure, and disease tracking systems can be linked to study and monitor possible health effects.


NAPHSIS is one of many EPHTN stakeholders, a group that includes federal, state and local health and environmental agencies, non-governmental organizations and academic research centers.


You can learn more about EPHTN through a course offered by the National Environmental Health Association (NEHA), called Environmental Public Health Tracking 101. Tracking 101 gives an overview of the National Tracking Network and Program, surveillance and epidemiology, tracking data, Geographic Information Systems (GIS) and communications.


NEHA is also offering a course called Tracking in Action: Workforce Implementation. Users learn how environmental public health tracking programs work with local health departments and community-based organizations. Tracking in Action presents real-life examples of grantee tracking programs and networks and how they have partnered with local programs and organizations to identify and address environmental public health concerns.
