DC, NY, Texas, and Michigan Lead Flu Index Detections

Launched in early November 2025, the Walgreens Acute Respiratory Index (ARI) for 2025-2026 tracks influenza and COVID-19 hotspots using prescription, testing, and over-the-counter product purchase data from its locations nationwide.

As of November 22, 2025, the District of Columbia, New York, Texas, and Michigan lead Walgreens' ARI index.

Nationwide, the overall ARI score was 2.5 out of 5.0.

Walgreens' unique digital tool offers a more comprehensive view of respiratory illness trends across the U.S., enabling the public, healthcare providers, and health officials to make more informed decisions throughout the respiratory virus season.

Rick Gates, Walgreens' chief pharmacy officer, commented in a press release, "Vaccination remains the safest and most effective way to prevent highly contagious illnesses like flu, RSV, and COVID-19."

Previously, the U.S. CDC FluView for Week 47 will be posted on November 21, 2025, stating 'seasonal influenza activity in the United States remains low nationally but is increasing.'

Various flu shots are offered throughout the influenza season at most community pharmacies.
