State health officials are reporting South Dakota's first flu detections of the 2014-2015 season--one case of influenza A and two of influenza B.

The State Health Department says the influenza A case was a Charles Mix County resident under the age of 10.

The influenza B cases involved a Lawrence County resident in the 60-69 age group and Pennington County resident in the 80-89 age group.

State epidemiologist Lon Kightlinger says now is a good time to be vaccinated.

He says yearly vaccination is the single best way to prevent the spread of influenza, and he says everyone over the age of 6 months should get vaccinated.
