FluSTAR, a novel influenza surveillance system: outcomes from the 2005-2006 flu season.

Background: The FluSTAR Surveillance System covers most of the United States, providing local and national information on influenza and influenza-like illness that is updated twice weekly.

Methods: Descriptive statistical analyses were performed to explore demographic characteristics, symptoms, vaccination status, and treatment of patients tested for influenza, using a rapid test kit, in the FluSTAR program during the 2005 to 2006 influenza season (October 1, 2005-April 11, 2006).

Results: Of 17,247 patients tested, the most common age groups were 35 to 49 (20%) or 19 to 34 years (18%). Overall, 22% of tests were positive. Patients testing positive were more likely to report influenza-associated symptoms such as cough and fever than those testing negative. Most patients testing positive were prescribed antiviral agents.

Conclusions: Surveillance systems such as FluSTAR can provide timely data on the circulation of influenza and influenza-like illness. This information could assist with accurate diagnosis and aid treatment decisions.
