US Governor Chris Christie defends Ebola medic isolation

US medics returning from treating Ebola patients in West Africa will be actively monitored but not placed in quarantine under new US health rules.

The federal guidelines came after a nurse was put in isolation in a tent in New Jersey, a decision condemned by UN Secretary-General Ban Ki-moon.

New Jersey Governor Chris Christie defended the mandatory isolation imposed on US nurse Kaci Hickox, who was quarantined when she returned home from Sierra Leone.
