Where Is Influenza Most Severe in December 2023

Most scientists say that having two independent data points empowers better decisions. This philosophy can be applied when determining the local health risk during the 2023-2024 flu season.

As of late December 2023, the U.S. Centers for Disease Control and Prevention (CDC) and Walgreens published updated maps and data identifying where influenza is being detected.

The CDC's FluView Updates for Week #50, ending December 16, 2023, reported seasonal influenza activity was elevated and continues to increase in most parts of the country.

And outpatient respiratory illness is above baseline for the 7th consecutive week and is above baseline in all 10 HHS Regions.

Previously, the Walgreens Flu Index® reported state and market-specific information regarding flu activity, which is compiled using retail prescription data for antiviral medications used to treat influenza across Walgreens locations nationwide.   

As of December 16, 2023, Walgreens identified the top ten states:

1. Louisiana
2. Mississippi
3. Alabama
4. Texas
5. North Carolina
6. Tennessee
7. South Carolina
8. New Mexico
9. Wyoming
10. Nevada

The good news from the CDC is that as of December 2023, over 153 million influenza vaccines were distributed this season, available today at most pharmacies in the U.S.
