Thanks everyone for your replies.

The only place she would have caught it them would have been at the shops again. Just glad we hadn't been to see any friends since then.

She's still not 100% but atleast she's stopped throwing up with is good. I think next time she gets it i will get the Dr to check her over really well or ask for tests if they can do them. Kimberley has had this 3 times in 10months. One time she ended up in hospital for the night and the only way to get fluids in was with a drip. I now worry each time she has it just in case we have to go through all that again.
