You may have to stay at your parents for more than one night. Some of these bugs can survive on surfaces such as door handles for days.
Can I recommend that you do a bit of research and find out what cleaning agents are best used, and then when you move back home you go armed with the right surface cleaners?
We have started to do a thing and we laughingly refer to it as Full On Virus Protocol (Mr B works in a job that makes him encounter many germ laden members of the public). As soon as he shows the signs of any vile lurgy, I ban him from the kitchen, and we wipe down door handles and bathroom fixtures. He doesn't touch the kettle or the fridge.
Works like a charm. Don't think I have caught anything from him since we started doing it a couple of years ago.
Sorry if that sounds a bit OCD. I think it is a but myself. But then... it woz the noro virus that started us doing this - and I NEVER want to experience THAT again.
