State health officials say the number of flu cases in Arizona increased sharply in the past two weeks.

The Department of Health Services reported 4,600 laboratory-confirmed cases so far this season, including nearly 1,600 in the past week.

The department says 177 pneumonia and influenza deaths have been identified so far this flu season in the state. That compares with 192 such deaths during the same period a year ago.

There's been one death of a child associated with the flu in Arizona. The department says the child in that case in Yavapai County had underlying conditions.

Health Services Director Will Humble said vaccine can still be found but that people wanting vaccinations should call locations first to make sure they still have supplies.
