Thanks my friends. Karis went home and is doing better today but her mom has it now too. I really don't know how long it lasts. Karis had it for 6 days and Mason has had it since Sunday. They are running more tests on Mason today so maybe we will find out something soon. Can I tell you how much I don't want to get this!!!!! I have been using clorox on everything but with Barbi living here and having Mason for 2 days when he is sick, I don't think clorox is really gonna help
