Both agree: Targeted guidance matters because officials have narrowed the likely source to cooling towers while ruling out tap water and home air conditioners as testing continues.
They split on: Whether the story is about government’s duty to give precise health guidance during a dangerous outbreak, or about containing disruption by avoiding unnecessary alarm beyond the affected zone.

New York City health officials are investigating a Legionnaires’ disease cluster on Manhattan’s Upper East Side.
As of July 6, officials reported 23 cases, 17 hospitalizations and no deaths linked to the cluster.
The outbreak is centered in the Upper East Side neighborhoods of Carnegie Hill and Yorkville, including ZIP codes 10028, 10128 and 10075.
Officials say the likely source is one or more cooling towers in the area, and the city health department is testing cooling towers in the affected zone.
Health officials have said the outbreak is not believed to be caused by building plumbing or the city’s drinking water, and residents can continue using tap water and home air conditioners.
Legionnaires’ disease is a form of pneumonia caused by Legionella bacteria, which can spread when people inhale tiny droplets of contaminated water from building water systems such as cooling towers.
The source of the outbreak had not yet been definitively identified in the reporting, so testing and investigation were still underway.
