The interactive online tool provides localized data on respiratory virus activity across the country. BUSINESS WIRE – Walgreens has launched the 2025-2026 Respiratory Index, an interactive online tool that tracks flu and COVID-19 activity nationwide using prescription, testing and over the counter (OTC) product purchase data from Walgreens locations nationwide. This unique tool builds on more than a decade of insights from the Walgreens Flu Index to now offer a more comprehensive view of respiratory illness trends across the U.S., helping the public, healthcare providers, and health officials make more informed decisions throughout the respiratory virus season. The Walgreens Respiratory Index will be updated weekly and will allow users to search by state to see where their geographic area ranks for both flu and COVID-19 activity. “The updated Index provides a clearer view of current virus trends, helping individuals make informed decisions to protect their health,” explains Rick Gates, Walgreens chief pharmacy officer. “Virus activity is expected to pick up as we head into the holidays, so now is the time to protect yourself and your loved ones by getting a flu shot and other recommended vaccines if you haven’t already. Vaccination remains the safest and most effective way to prevent highly contagious illnesses like flu, RSV, and COVID-19.”
