Rest assured I was NOT trying trivialise Ebola or indeed turn it into a North South argument but in any other country the message would be rammed home that ALL border entry points regardless of geography, should be under the same critetia not a select few.
As you state 90% of traffic is coming through LHR LGW Eurostar so therefore 10% might permutate through other points of entry, shall we say it again ....that's 10% !
Well the US is "any other country" and I thought they had applied screening to 5 airports that receive 94% of travellers from West Africa. I would have thought that 6% of traffic into the US is a considerably larger number of people in absolute terms than 10% of traffic into the UK. Maybe not. The principle is the same though, is it not ?
