The Flu Index provides valuable insight by showing which cities or metropolitan areas are experiencing the most incidences of influenza each week based on Index methodology. The data does not measure actual levels or severity of flu activity.

With the ability to generate hyper-local data across most U.S. markets, the Flu Index is an online, interactive resource allowing anyone to search and find information regarding the most current state of influenza in their community.
