CDC’s Tracking Network in Action

CDC's Environmental Public Health Tracking Network (Tracking Network) is a dynamic surveillance system that provides information and data about environmental hazards and the health problems that may be related to them. It presents what is known about where environmental hazards exist, where people are exposed to hazards, and how targeted action can protect health, reduce illness, and save lives.

Data in the National Tracking Network comes from 24 funded state and local health departments, CDC programs, and other government agencies. Since the network launched in 2009, public health officials have used city and state tracking networks to identify trends such as increased seasonal asthma rates, patterns of illness related to extreme heat such as cardiovascular disease complications, and areas with people at high-risk of consuming contaminated drinking water. The Tracking Network is a unique resource that brings together information that cannot be found, or is hard to find, anywhere else.

The Tracking Network's data are used for a wide variety of environmental and public health efforts. In the "Tracking in Action" video series, you can see how four tracking programs used their local networks to make important, lasting contributions to the health of their communities.

  • New York City's Tracking Program provided data to local health care providers to help reduce asthma hospitalizations among children.
  • Florida's Tracking Program worked with local health officials to create and distribute an easy-to-carry wallet card that informs about healthy fish consumption.
  • Massachusetts' Tracking Program worked with local health officials to protect air quality in Norwood with the arrival of a new asphalt plant.
  • Missouri's Tracking Program worked with local health officials to create an interactive, dynamic online map that makes cooling centers easy to find.
