Walgreens Flu Index for Week of December 6, 2015

PRESS RELEASE

DEERFIELD, Ill., December 10, 2015 - While Walgreens Flu Index™ data suggests a slight increase in flu activity in some markets, overall activity remains relatively low across most of the U.S. The Walgreens Flu Index is a weekly report developed to provide state- and market-specific information, and ranking of those experiencing the highest incidences of influenza across the country. The Flu Index does not provide data measuring actual levels or severity of flu activity, but rather, illustrates which populations are experiencing the most incidences each week based on Index methodology.

This Smart News Release features multimedia. View the full release here:http://www.businesswire.com/news/home/20151210005834/en/

With the ability to generate hyper-local data across most U.S. markets, the Flu Index is an online, interactive resource allowing anyone to search and find information regarding the most current state of influenza in their community.

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.
