What may need to happen is forced 21 day quarantine for all HCWs that care for active ebola cases, buth overseas and here.
It will not be popular, and will greatly increase health care cost of caring for these patients, but just letting nurses and doctors wander around after working with ebola is not safe at this time.
So if a team signs up to treat ebola, they are locked in minimum of 3 weeks after last exposure.
Got my vote!
