Thanks for all the good wishes! Kels has been given antibiotics that would seem to indicate it's just a virus rather than full on swine flu. I have to keep an eye on her temp for the next 24 hours and keep on with the paracetamol, ibuprofen and fluids! ( looks like I did actually know what I was doing after all!

) NHS direct website advises you to contact GP which is what I did, and not to take to hospital unless condition worsens or there are underlying medical conditions, I did the checklist last night and it is quite clear on that. ( also available in large print for those of us with comprehension problems).
Also for info Accyman is correct about the out of hours pharmacy on Townsmoor retail park but it's only open till midnight.

PS thanks to Derek and to Em for offering help, much appreciated.
