The CDC Behavioral Risk Factor Surveillance System

The Behavioral Risk Factor Surveillance System (BRFSS) is used in the United States as a state-based system of health surveys that collects information on health risk behaviors, preventive health practices, and health care access primarily related to chronic disease and injury.

The timely data on health related behaviors obtained by BRFSS is used by states to identify and track health objectives, and develop and evaluate public health policies and programs.

The 2009 H1N1 ILI module is able to indicate how much ILI is reported in the participating states and territories. When participants report that they have had ILI, they are asked follow-up questions, including whether they sought medical care for their illness. Participants are also asked whether anyone in their households were hospitalized for ILI. These data are supplemental to CDC’s weekly FluView surveillance system and provide additional information about ILI, and also about behaviors related to influenza.

Country offices can learn more about the BRFSS at and possibly develop context specific questionnaires of their own.
