Thousands of schoolchildren across Britain have become sick from a mystery illness - known as the vomiting virus!
Have you or your school been affected by this? In what way?
And are you concerned that so many children are getting this bug?
Or are you so healthy that you'd still be standing no matter what?

I had the virus and it isn't nice, I vomited three times in four days and most of my school have it.

Loads of people in my school have been off with some kind of virus, I don't think it was the vomiting one though, some people claim they have been feeling sick.
Chris, 12, Cardiff
I'm not really worried no one really is that sick at school apart from the occasional flu.
Amber, 12, Frome
I myself had the virus, but don't know anyone else but me who has had it! It's weird because the last I was sick was when I was 8 yrs, I'm hoping that I won't have anything like it for a long time, if possible NEVER AGAIN!
Storm, 14, Bognor Regis
I have been off school today and yesterday because of this illness. Most of my friends have had it too and I must have caught it off them!
Rosie, 15, Preston
Today there was only 8 people in most of my classes, and most of my friends have gone down with it and now I'm worried to because it is going around so quickly and both my sisters have it as well!
Hannah, 12, London
Most of my friends have got it and even my form tutor had it and now there's only about 15 left of us out of 30.
Steph, 13, Harlow
I have recently had this vomiting virus and it came on all of a sudden. It passed through my family in a matter of days. It is the worse illness I have had in a long time but fortunately it only lasted a couple of days.
My school hasn't been hit, but my Dad has been really sick lately.
Carla, 13, Oxfordshire
I have been ill for a very long time, and I have only just recovered. I really hope I don't get ill again!
Bekky, 11, Trowbridge
I have been OK but only 13 were in today out of 28 in my class!
Emily, 13, Glossop
Students at our school seem to be OK but people are gradually being off school because they are vomiting and have stomach upset. It sounds horrible! - I hope I don't get it.
Rachel, 13, Cambridge
I am a little bit worried although I don't get sick too often. It's a bit shocking, really!
Rachel, 14, Kent
My best friend has it and It's a real shame. She's been off school for 3 days. People say it'll blow over after a few days but I'm still worried.
Mandi, 12, Glasgow
I hardly ever get sick but now I'm worried.
Dan, 12, York
Me and my brother are scared that we may catch it and HAVE TO miss school work.
Josh, 12, Wakefield
Lots of people at are our school have been having days off and coming back and saying that they keep vomiting.
Jon, 13, Telford
I can't believe that this virus is spreading so quickly.
Claire, 12, London
I have just had the bug and I haven't been sick in years! Also loads of my friends have got it. The good thing about it though is that the teachers all have it and the people who cover for them keep forgetting to give us homework!
Charlie, 12, Southampton
It don't worry me the smallest bit!
Ben, 11, Northampton
Our school hasn't been affected, and I really hope that it doesn't because I can't afford to miss any school, I have to do GCSE work!!!
Sarah, 15, Grimsby
In my school, there are a few students affected by this illness. These days I'm worried about this virus, so many times I don't want to go to school.
Sarah, 13, Manchester
Our school hasn't been hit yet but I hope it doesn't because we have exams shortly!
