Why the military needs to be quaranteed is simple.

The military is there erecting facilites and as support for the medical professions treating Ebola patients.  They are not working in hazmat suites.  They are, therefore,  more exposed.

The state department employees would have little or no contact with and therefore little exposure to Ebola.  Ergo, they would not need quaranteen, but rather monitoring.

Medical professionals should be guided by best medical practices, not a politician’s bullying.
