Flu A is the predominate strain that's making people sick this season.
According to the CDC, Miami-Dade has seen 3-4 outbreaks since Jan. 6. There have been no outbreaks over that time in Broward.
Doctors think the increase in flu cases may be in part because the flu vaccine may be less effective than usual this season. The CDC says it's usually 50 percent effective. This year the flu shot is about 32 percent effective.
Central Florida has seen a few deaths, according to state health officials, who worry the death toll could rise since the number of flu cases is increasing.
