"Even before the virus began in Iowa, our office was monitoring the outbreak in other states. We'll continue our work—as we've been doing since the first outbreak in Buena Vista County—in hopes of stopping the virus' aggressive spread throughout Iowa."

The governor's plan to tackle the outbreak includes containing the spread through "depopulation, disinfections, and disposal of livestock carcasses." The plan will also allow for a temporary suspension of regulations pertaining to commercial vehicle drivers hauling the infected poultry carcasses.
So far, an estimated 16 million egg-laying chickens in Iowa are in infected or presumed infected farm facilities - meaning that at least one-quarter of the state's flock will have to be killed and disposed of, state officials said.
