With flu activity winding down in the U.S., Walgreens today announced the top markets (DMAs) and states for flu activity for the season, according to its season-ending Walgreens Flu Index™ examining aggregate prescription data from November 2015 through mid-April 2016.

The states with the highest rates of influenza, according to the Index, were Arizona, Texas, Kentucky, Mississippi and Tennessee.

The Walgreens Flu Index provides state- and market-specific information regarding flu activity, and is compiled using retail prescription data for antiviral medications used to treat influenza across Walgreens locations nationwide. With the ability to generate hyper-local data, the Index continues to be instrumental in driving consumer awareness and prevention across the United States, while also serving as a valuable tool for health departments, media and others at the local level.

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 10 retail locations.
