I just found out this morning that my niece, Alexis, has the chicken pox. I called our pediatrician and what she told me was..... it starts out with symptoms just like the "virus" she had last week. GREAT! Now that they know she was exposed to someone with chicken pox, they say it is more than likely that she has caught it. I guess they are contagious from 7-21 days before they break out in the "blisters" Wow, this is going to be fun.
