Launched six flu seasons ago, the Walgreens Flu Index is an online, interactive tool to view flu activity across markets and states in the U.S., including Puerto Rico. Each week, we analyze prescription data for antiviral medications used to treat influenza across thousands of Walgreens and Duane Reade locations nationwide. In addition to the top markets and states, the Flu Index also ranks the markets and states experiencing the greatest gains in activity on a week-over-week basis.

A new feature of the Walgreens Flu Index for the 2019-2020 season allows you to see how current flu activity compares to last season. October data show southern states are experiencing more widespread flu activity this year. Index levels are higher in Texas, Louisiana, Mississippi, Alabama, Florida, Oklahoma and Nevada compared to this time last year.

The only thing predictable about the flu is that it’s unpredictable. According to the Centers for Disease Control and Prevention (CDC), the best way to protect yourself and loved ones is by getting a flu shot every season, ideally before the flu starts to spread in your community.
