I have the same policy as you....if a child throws up they are instantly sent home. I do feel bad because there are often times that it's a one time thing but unfortunately we don't know that at the time. I am responsible for all the children in my care and part of that responsibility is keeping my home and daycare clean and as germ free as possible! I have never had a parent refuse to come get their child but I have had a parent say they couldn't come for a few hours. I allowed this as it was nap time anyways and her child slept in a different room. I have worked at places where it was not always easy to leave (ratios had to be met) so I do understand but I do think that if a family chooses home daycare than it is their responsibility to have a couple back ups for emergencies like this.

If it was a common issue with the same parent I would probably ask them to find alternate care but give them a month's notice. It would also depend on the demand though...right now the demand isn't high in my area so I wouldn't want to take the decrease in pay.
