This year's flu season is matching levels seen in 2009.
Florida Epidemiologist Carina Blackmore said cases are higher than last year and started a little earlier than normal.
Blackmore said south, central and some north Florida counties are experiencing more cases of the flu than other parts of the state. She adds, however, that it is hard to predict the future of this flu season.
"We can't say that it's going to get better," she said. "It can get worse still."
The flu virus changes every year. The vaccine for this season matches the current strains of the virus, she said.
Blackmore said there have been no reports of shortages for vaccines and urges everyone to get one to stay free from the flu this season.
"We really push the vaccination as the best tool that we have against flu," she said.
