ORLANDO, Fla. - Channel 9 has learned local Centra Care facilities saw 40 flu cases on Monday, which is double the number they've been dealing with on a daily basis.
This year, a majority of viruses are H1N1, commonly known as the "swine flu," officials said.
"What you are being immunized against right now this year is the same strain we are seeing in the community this year," said Dr. Tim Hendrix.
Winter Garden saw the most cases last week, with one Centra Care seeing 20 cases overall.
Locations in Waterford Lakes, Sanford and Buena Vista weren't that far off. Each had 15 cases last week.
Hunters Creek also had 14.
If a trend similar to 2012 continues, central Florida could see more than 600 cases during the virus' peak.
Doctors worry the numbers are just the beginning because families will begin gathering for the holidays, which could lead to more cases.
Sand Lake and Azalea Park saw the least cases of flu last week with only one case each.
