Walgreens has released its weekly Flu Index data to show
specific flu activity throughout each U.S. state and its markets, ranking them according to the highest incident rates.
The index doesn’t give data that shows the severity or exact levels of influenza activity. Instead, it uses index methodology to show the populations that have the highest incidences every week.
For the week that ended Dec. 6, the 10 states with the most flu activity were Texas, Alabama, Mississippi, Oklahoma, Nevada, Tennessee, Kentucky, Nevada, Florida, South Carolina, and Louisiana. The 10 states with the highest gains in flu activity include Texas, Nevada, Alabama, Florida, Alaska, New Jersey, West Virginia, South Carolina, Tennessee, and Arkansas.
Analysts at Walgreen’s gather weekly retail prescription data specifically for antiviral medications for influenza. This data is taken from Walgreens stores throughout the U.S. The end result measures the incremental change and absolute impact of antiviral medications for the average basis of each store.
