Environmental public health tracking: driving environmental health information.

Context: Historically, public health professionals lacked the capacity to evaluate and conduct key investigations into the health of their environment. By bringing together environmental and health effects data from a variety of data sources, the National Environmental Public Health Tracking Network (Tracking) allows users to easily analyze and research the relationships between human health and the environment.

Objective: As the Tracking Network has matured, its information has been used to guide public health actions, generate hypothesis, and demonstrate relationships between environment and health outcomes.
