Oklahoma, Texas had most activity for 2014-2015 flu season
Other states with higher flu activity levels were Mississippi and Tennessee.
In contrast, the areas with the lowest levels of flu activity were Boston (Mass.), Hartford (Conn.) and Portland (Ore.).
The Flu Index recorded flu activity levels from Nov. 2014 to Feb. 2015. The index draws its information from aggregate prescription data, using information that is both state and market specific. It collects its data from Walgreens stores across the U.S.
The goal of the index is to improve the ability of health professionals to prevent the spread of influenza. It also encourages awareness about the flu and prevention among communities.
“In just its first season, the Flu Index quickly became a resource that people -- and news media in particular -- came to rely upon, and strong awareness helped deliver a call to action that had a positive impact on flu immunization rates,” Richard Ashworth, Walgreens president of pharmacy and retail operations, said. “This is another way in which we’re helping to better the health of our communities by providing the preventive health information and services they need.”
