The secretary shall develop a formula for distribution of any federal and state funds appropriated in the omnibus appropriations act on or before July 1, 2006, to local health jurisdictions for development and implementation of their pandemic flu preparedness and response plans. The formula developed by the secretary shall ensure that each local health jurisdiction receives a minimum amount of funds for plan development and that any additional funds for plan development be distributed equitably, including consideration of population and factors that increase susceptibility to an outbreak, upon soliciting the advice of the local health jurisdictions.
