Sadly, there's no point in vacating the premises now, as you've been exposed to the contageous period for a good 5 days now :-(
Once you've had Chicken pox, you cannot contract it again, however the varicella-zoster virus does lie dormant in your system for the rest of your life and can return at a future date as Shingles. I've had both, and Chicken Pox was a walk in the park compared to shingles.
Getting Chicken pox for the first time as an adult does make for a nastier time of it, but complications are pretty rare, even for those with an underlying medical condition.
Personal question (sorry), but if there's any chance you might be pregnant you might want to see your GP as CP is one of those things to be avoided like the plague during PG.
Hope your daughter has a fairly easy time of it, and that her 'itchies' don't drive her (or you!) round the bend too much!
