Secure borders is a major issue for everyone, whether they know it or not. This ebola outbreak has not followed previous patterns. It began in the cities instead of the boonies. People travel quite a lot so it is not a stretch to think we need to be cautious.
The way the government is confining large groups of people in small areas at the border and then scattering them like the wind before they are thoroughly medically checked it is a terrific way to spread any disease.
I certainly don’t dispute any of that (although, of course, jungle primates are the hidden reservoir of Ebola and the true origination point).
The recent influx of central Americans IS likely to spread diseases otherwise uncommon here, but at this point Ebola isn’t one of them.
Much more likely to arrive “legally” from the African continent.
