Hillingdon is very close (FWIW Uxbridge Magistrates Court, nr Hillingdon, is where Heathrow criminal cases always go) but there is also Ashford & St Peters at Chertsey - similar distance I think. They have swine flu inf on their home page. Hillingdon Hosp home page is here. Maybe worth ringing both for advice?
Who knows? We've had a nightmare with NHS24 and NHS Direct. But we've decided not to take any risks and he's coming straight home and going into quarentine in the spare room for tonight. He's had it for 6 days so he should be feeling better by now and appaerently over the most infectious stage. If he's not feeling better in the morning then I'll take my dd to my mothers for a night or 2 until he's better.
