The first confirmed flu case of the season has been reported in Maricopa County, said the Arizona Department of Health Services.

State health officials said an unvaccinated child contracted the contagious respiratory illness, but was not hospitalized.

Last flu season, more than 1,900 cases of the illness were reported in Pima County. But Michael Acoba, the epidemiology program manager for the Pima County Health Department, said that’s not telling for this season.

“It's very difficult to predict whether or not we are going to have a bad flu season or a good flu season, meaning a relatively few number of cases," Acoba said.

He said the best defense against the flu is getting vaccinated.

Acoba said people can get the vaccine from their healthcare provider or at their local pharmacy. He added Pima County offers free flu vaccines to people 18 and younger.
