Since the Centers for Disease Control and Prevention started work on building a network of hospitals to provide effective Ebola patient care earlier this year, only a couple dozen American facilities - a tiny fraction of the more than 5,000 hospitals across the country - have volunteered their services. That's because concerns about exorbitant health care costs, unwanted attention, and the fears of other patients loom large among hospital administrators, further complicating the Obama administration's plans to set up one Ebola facility in every state and provide additional support in New York, Chicago, Puerto Rico, and Washington, D.C., as outlined in a $6 billion emergency fund request .
