There should be more panic.
If we aren’t going to quarantine travelers leaving those countries at the start of the trip, they should be quarantined at the end of the trip. At least long enough to do a blood test and reduce the odds that they are infected. And they should be quarantined at home for the duration of the 21 days.
CDC’s insistence on non-quarantines are going to get people killed. They already had two near misses with the nurses in Dallas.
Blood on their hands.
