Unfortunately, I can't turn children away at the door due to a virus, but I can suggest when they get as bad as the poor little girl you are describing that they take her to the doctor to check for chest infection and ear infection. I always tell the parents that those are things only a doctor can diagnose because they aren't visible to our eyes. Once the parents have gone to the doctor at least you will know if it's viral or bacterial and can warn the parents of the other children.

Something else I say to parents when a sickness is getting out of hand - I'm here to protect all the chidren and you wouldn't want me to allow another sick child in care to infect YOUR child. So I have to ask you if you could take a sick day with your child to protect the other children.
