Syndromic surveillance serves as an early alert for health events by tracking symptoms such as respiratory distress, fever, and vomiting—before a diagnosis is confirmed. Emergency departments and other sources send this information as electronic data to public health agencies. These data are monitored daily to understand usual levels of illness and to detect changes that require a response.

CDC’s National Syndromic Surveillance Program (NSSP) helps connect local, state, and national public health agencies to data from more than 4,000 healthcare facilities in 45 states, and Washington, DC. This allows officials to unite nationwide and act quickly when something unusual happens, and to monitor how well their response is working and adjust as needed.
