The Walgreens Flu Index is a weekly report developed to provide state- and market-specific information regarding flu activity, and ranking of those experiencing the highest incidences of influenza across the country. With the ability to generate hyper-local data that's as specific as a single zip code, the Index aims to drive consumer awareness and prevention within communities, while also serving as a valuable resource for health departments, media and others at the local level.

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.
