Hi I'm new here because I need to know there is other people with my fears also. Anyway, the worst possible case has happened, the vomiting bug is going around my family, already affected 3 of my aunts and two of my cousins.

My sister comes into contact with my cousin and my aunt everyday (she goes to school with him and is going on a sleepover tomorrow) they both said they are fine but I know the person contagious 24+. Is there anyway to prevent this reaching my family. Thank you
