Methodology

The Walgreens Flu Index™ is compiled using weekly retail prescription data for antiviral medications used to treat influenza across Walgreens locations nationwide. The data is analyzed at state and geographic market levels to measure absolute impact and incremental change of antiviral medications on a per store average basis, and does not include markets in which Walgreens has fewer than 20 retail locations.

The Flu Index™ is not intended to illustrate levels or severity of flu activity, but rather, illustrate which populations are experiencing the highest incidence of flu.
