you are contagious for 48 hours after your last chuck or trots.
I know it sounds like a long time, but that is the recommendation.
So you need to lay low for a couple of days after you have finished.
Gastro is nasty and the last thing you want to do is pass it on!!!

make sure that you spray the toilet everytime you go with a disinfectant spray like glen 20 including the toilet seat and door handle. Also any surfaces you touched need to be sprayed with anti-bacteria spray.
Try and use the same cultery and crockery as well, and dont wash them with the rest of the families dishes. They need to be washed separately.

Also, if kids get gastro, buy some anti-bacteria wipes and wipe over as many of their favourite toys as you can with them! It really stops the gastro from coming back

make sure that you are constantly washing your hands as well with anti-bacterial soap as well- not just normal soap. and any soiled clothes should be washed separately with as hot water as allowed and dried in the dryer.
Make sure that you are the only one using the one towel to dry yourself as well, esp your hands and face.

i hope these tips help. MY DH job is food safety, so if anyone gets gastro we have to be deligiant that it doesnt spread as he cant afford to get it with his work. So far the kids have only had gastro a couple of times and we have managed to contain it following these measures.

Hope you are feeling better soon and take care
