Walgreens introduced a new Flu Index, which is a weekly report providing state- and market-specific information regarding influenza to help identify areas where flu cases may be escalating.

Developed to serve as a valuable resource for health departments, media and others at the local level to help drive consumer awareness and prevention within their communities, 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.
