I think she is taking the piss.
When dealing with something dangerous such as using a firearm, operating dangerous machinery, or dealing with a potential outbreak of a leathal virus, you put several safe handling protocols in place to stop the shit hitting the fan.
That way if one or two or three are breached by accident or by ineptitude there will be another three or four in place.
If she has not got Ebola, that’s good it means the previous measures that have been put in place to protect her getting ebola have worked and the worst that can happen is she has to stay quarantined for 21 days unnecessarily, big deal.
If she has got Ebola and she does not stay quarantined, what is the worst that can happen.
And it is not just about her, there are hundreds of good people out in Africa trying to help beat Ebola and can only hope they don’t pay dearly for doing so but why take unesasary risks that could end in dire consequences for the sake of three weeks.
