This does nothing. I believe we would learn if they were sick even without this monitoring . This I just for spin.

I wouldn't say this does nothing. Yes, we would learn if they were sick even without monitoring, but I think the point of this monitoring is to identify potentially sick people faster.

The main window for transmission of Ebola is the time between when someone begins showing symptoms and the time at which they are diagnosed as having Ebola (or suspected of having it) - they are not contagious before the onset of symptoms, and after they are diagnosed tgey will be isolated. So, the more we can narrow that window, the less likely it is that the virus will be transmitted.
