FluView

Overview
CDC collects, compiles, and analyzes information on influenza activity year round in the United States and produces FluView, a weekly influenza surveillance report, from October through mid-May. The collection of these data enables CDC to:


 * find out when and where influenza activity is occurring
 * track influenza-related illness
 * determine what influenza viruses are circulating
 * detect changes in influenza viruses, and
 * measure the effect influenza is having on deaths in the United States.
