ST. PAUL (AP) -- Four hospitals in Minnesota have been designated as treatment centers for any confirmed Ebola cases in the state.

The Minnesota Hospital Association announced the designation Friday.

The four are the University of Minnesota Medical Center in Minneapolis, Mayo Clinic Hospital in Rochester, Allina Health's Unity Hospital in Fridley and the St. Paul campus of Children's Hospitals and Clinics of Minnesota.

Minnesota Hospital Association president and CEO Lawrence Massa says hospitals across Minnesota have been ramping up for the possibility of an Ebola patient arriving on their doorstep.

But Massa says what happened in Dallas - where two nurses contracted Ebola after caring for a man who died of the virus - showed Minnesota needed to rethink its plan.

Any Ebola patients in Minnesota also might be transferred to one of four federal biocontainment facilities.
