My son used to interview asylum applicants. He developed a terrible chest and cough that lasted for ages. I pestered him to go to his GP and ask for a test for TB, which, as many will know, was virtually irradicated from this country years ago. Maybe some more 'mature' PPRuNe members will remember, as I do from my childhood, the isolation hospitals that were dotted around in those days!
The GP stated that such a test would not normally be given on request, however, when my son revealed what he did for a living, within the week he was tested! Luckily he was clear.
So, makes one think does it not? As we have a pretty open door now in the UK, I reckon we'll see a lot of the old afflictions and diseases returning in the not so distant future.
