I agree with Tan, but also...When I was working in childcare, we also used to have a rule that if they need their noses wiped by a carer (as in they're too little to wipe their own, or it too much snot for them to handle, lol) every 10mins, then they should stay home too. If she's coughing alot and spluttering her germs everywhere too (and spreading them around), then I would say keep her home one more day as well.
