This virus (or whatever it is, is running wild in my neck of the wood as well).  So far both of my kids have dodged it (PTL).  My prayers are with you and your daughter.  The Solu-Cortef that was left in the car (if it was in the cold) might not be any good, due to the fact that the Solu-Cortef is sensitive to temperature.  I have accidentally left mine out in the cold and pitched it because of this.  I don't want to take any chances with it not working when I really need it.  In a few days, let us know how she is doing!
