Ebola crisis: Concern over US protocol 'breaks'

The man who was in charge of US public health during the 9/11 attacks has expressed "concern" about US health protocols following the Ebola diagnosis of two Texas health care workers who treated a Liberian patient.

Dr Richard Carmona, former Surgeon General of the US, told the BBC there could be more infections if there were breaks in the protocols set up to protect health care workers.
