I do exactly as playfelt stated and have a quieter day. Fever of 101F or vomitting or diarrhea or severe contagious diseases mean that the children should not be at daycare. However, there is nothing you can do about a virus and your description sounds like a child fighting a virus Daycare123. I kinda feel like that myself today!

The first thing I do is take a child's temperature and take it periodically throughout the day when they behave as you described. I worked outside the home all my life and I guess I see things from the parents point of view because employers are really being horrible when people use their sick days over the past several years.
