Does swine flu always cause a temperature?

[JennyPenny22]

My 2 have been not well today. Colds, grumpy and extra sleep.

But neither of them have a temperature.

Swine flu is big in our area and a little girl died a few days ago - just a 5 min drive from our home . Most of the schools round here have had cases etc.

can i ask if you have to have runny nose too, ive been told i have it but no runny nose, sneezing or coughing.
