Walgreens Launches 2016-17 Flu Index™ to Show Top Markets and States for Flu Activity Each Week

Index now includes Puerto Rico as part of hyper-local data for media,
health officials and consumers; Puerto Rico and Reno, Nev. top the list
for activity this week

DEERFIELD, Ill.–(BUSINESS WIRE)–Walgreens today launched its first Flu Index™ for the 2016-17 season, a
weekly report that ranks the top markets and states for flu activity in
the U.S. This year’s Flu Index will include Puerto Rico for the first

Now in its third year, the Walgreens Flu Index is compiled using the
drugstore chain’s weekly retail prescription data for antiviral
medications used to treat influenza across Walgreens locations
nationwide and in Puerto Rico. In addition to the top markets and states
for activity, the Flu Index also ranks those experiencing the greatest
gains on a week-over-week basis.

“While flu activity remains relatively low across most of the U.S., our
data suggests a gradual increase in incidences of flu in a growing
number of markets,” said Richard Ashworth, Walgreens president of
pharmacy and retail operations. “Even with a slower start to flu season,
the Flu Index helps health officials, media and consumers stay informed
about the flu in their local community.”

Data for the Walgreens Flu Index 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.

The Index is not intended to illustrate levels or severity of flu
activity, but rather, based on this methodology, to show which
populations are experiencing the highest incidences of influenza within
the U.S. and Puerto Rico each week.
