PRESS RELEASE

DEERFIELD, Ill., December 17, 2015 - While flu activity remains low or moderate across most of the U.S., Walgreens Flu Index™ data suggests a gradual increase in incidence of flu in a growing number of markets. 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.

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.
