ARCHIVED - CT DPH Influenza and COVID-19 Syndromic Surveillance by Week

Syndromic surveillance provides public health officials with a timely system for detecting, understanding, and monitoring health events. By tracking symptoms of patients in emergency departments—before a diagnosis is confirmed—public health can detect unusual levels of illness.

Syndromic data can serve as an early warning system for public health concerns such as influenza and COVID-19 outbreaks.

These data represent the percent of emergency department and urgent care visits related to Influenza Like Illness or COVID Like Illness.
