Walgreens launched its 2026-2027 Flu Index on October 21, 2026, revealing that respiratory illness activity is tracking four weeks ahead of recent years. The national flu activity score currently sits at 2.31 on a 0-10 scale.
Why it matters
Early spikes in respiratory illness provide critical insight into the severity and timing of the upcoming flu season. Increased sales of over-the-counter medications and testing kits reflect a surge in demand as the country enters the peak illness period.
The index reports a national flu activity score of 2.31, with Hawaii leading the nation at 5.95. Year-over-year sales for cold and flu medications have climbed 17.7%, while at-home testing kits have seen an 11.5% increase.
