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.
