Army Gen. Martin Dempsey, the chairman of the Joint Chiefs of Staff, signed a plan that lists Fort Hood and Fort Bliss, Texas; Fort Bragg, North Carolina; Joint Base Lewis-McChord, Washington; and Joint Base Langley-Eustis, Virginia, as bases where troops would be quarantined. The U.S. also hopes to use two bases in Italy and Germany for returning troops based in that region.

Glad they have a place to put them but why spread them out like that unless its just to be closer to their homes or unit? And why risk spreading it into two other countries ?
