Flu season is here. Walgreens has just launched its first weekly Flu Index for the 2015-’16 season. Walgreens states the 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."

The Walgreens Flu Index portal provides a geo map color coding the top ten markets as well as activity by state.
