I Think We Have Had The Norovirus Bug Whilst On

I think we have had the norovirus bug whilst on holiday. Myself, my husband and 12 year old daughter were very sick and had dioherrea on Sunday night all night. We are much better but my 12 year old still looks very pale, is complaining of being very tired an doesn't want to eat much 36 hours after last being sick. Is this a normal reaction?
