"Of course there would be a problem with illegal entrants but that aside there's no need for health checks at the airports. "
Half of the reason I proposed that, at least, was because people are always, with good reason, calling for tougher border control. It seemed to me that a mandatory health check could form a natural part of that, so I thought it a not unreasonable suggestion.
Naomi, perhaps I was giving Nigel Farage too much of the benefit of the doubt in my second post, then. I think it's entirely unfair to talk of "abuse" of the system in this context without at the same time either implying that foreign nationals were deliberately getting infected or chastising them for the entirely reasonable point that they are sick and want and need treatment for said sickness. Under such circumstances it seems harsh at the very least to blame such people for the situation they are in. The term abuse is uncalled for and, whether Farage meant it or not, leaves him open to the criticism I suggest. I suspect he probably did, really, but will find a way to cover himself. Either way, it was a poor choice of words.
As to NJ's point -- maybe other countries wouldn't be so quick to throw treatment at immigrant AIDS victims. Ultimately, this is short-sighted, though, because either you have an untreated AIDS victim in your own country (and so the disease is bound to spread), or you have such a person running around another country in which case it will spread there (and, inevitably, come back here). When it comes to disease in particular, we can't afford to be so national in whom we treat. Under those circumstances, the £50 million odd is probably money well spent if it helps to keep the spread of the disease in check.
