I should add that, this thing can take up to 21 days to fully manifest itself with visible symptoms. That means there is massive potential to be infected without anyone noticing, whilst still spreading it. Just because it can only 'officially' be transmitted by bodily fluids does not mean you need to stick your tongue down their throat to contract it. The correct procedure to nip this in the bud early would be to test everyone entering the country from anywhere. Of course that is impractical, and that is the reason that one day we will be caught with our trousers down.
