Tracking Extreme Heat

CDC’s Environmental Public Health 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 we know about where environmental hazards exist, where exposures happen, and how targeted action can protect health, reduce illness, and save lives.

The Tracking Network is a unique resource that brings together environmental and health information that cannot be found, or is hard to find, anywhere else.
