EARS Early Aberration Reporting System

Photo of EARS staffThe 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 capitol 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, 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.

The EARS program presents its analysis in a complete HTML Website containing tables and graphs linked through a home page. Viewing EARS output requires only a Web browser.

EARS's graphing capabilities have been especially popular among its users.
