(FOX19) - Officials say H1N1 is the strain which will most likely get you sick this year.
That's the same strain that caused the 2009 swine flu outbreak. Hospitals are already treating thousands of patients.
Several deaths have been reported and the worst is still to come. Doctors say staying healthy is key.
Doctor David Grossman of the Toledo-Lucas County Heath Department says, "Avoiding people who are sick, in areas where you know someone is sick, you don't want to put yourself there because that's how the virus spreads."
Doctors say young children and anyone 13 to 50-years-old are most at risk. The good news is that pharmacies are reporting full supplies of the vaccine.
