The Walgreens Flu Index® recently coded the top 10 United States cities experiencing the most influenza detections. The Index shows flu activity is 50% higher than last week.

As of November 18, 2023, the updated listing includes cities primarily located in the south-central U.S.:

1. Harlingen-Weslaco-Brownsville-McAllen, Texas
2. Lafayette, La.
3. Beaumont-Port Arthur, Texas
4. Houston, Texas

While various flu shots are readily available at most clinics and pharmacies in October 2023, about 15% of individuals who received their flu shot at Walgreens were millennials, and only 9% were Gen Z. 

The Walgreens Flu Index® is an online, interactive tool showing the most significant increases in flu activity week-over-week.
