EARS Early Aberration Reporting System

Photo of EARS staff

The Early Aberration Reporting System (EARS) was pioneered as a method for monitoring bioterrorism during large-scale events. Its evolution to a standard surveillance tool began in New York City and the national capital region following the terrorist attacks of September 11, 2001.

Various city, county, and state public health officials in the United States and abroad currently use EARS on syndromic data from emergency departments, data collected at shelters after disasters, reportable conditions, 911 calls, physician office data, school and business absenteeism, and over-the-counter drug sales. EARS is convenient, easy to use, and available at no cost.

For more information, explore this site, view our fact sheet, or contact the EARS project.
