(KNZA)-- The Kansas Department of Agriculture says they’ve found new cases of avian influenza in commercial game bird operations Doniphan and Rooks Counties.

Other than a few cases recorded in backyard poultry flocks and wild birds this fall, the bird flu hadn’t hit commercial flocks in Kansas since early spring.

The news comes as human cases of the bird flu tick up. The Centers for Disease Control and Prevention says more than 60 human cases have been recorded this year, including the country's first severe case announced last week in Louisiana.

Health officials say the risk to the public remains low.
