Health officials are confirming the first flu case of the season. Both the state and Maricopa County say an unvaccinated woman in her early 30's is now recovering at home.
Maricopa County Department of Public Health Director Dr. Bob England says they don't know which flu strain will dominate flu season this year.
The Centers for Disease Control and Prevention recommends that everyone 6 months and older get the flu vaccine.
This year's flu vaccine protects against H3N2 virus, an influenza B virus and the H1N1 virus that caused so much illness last season.
Last year Arizona had 13,032 flu cases and at least 122 deaths, almost all due to the H1N1 pandemic strain.
