I'm in northern VA (close to Dulles) and am on chicken pox watch with my kids. They were exposed to chicken pox 15 days ago. I was also able to expose them to a child with "fresher" chicken pox on Tuesday. I assume it's very likely they will come down with it.
I know the opportunity to get the chicken pox doesn't come too often so if anyone is interested in a play date to get exposure, PM me.
Will update this thread with their status.
