While shingles typically affects older adults (the older you are, the higher chance of getting
shingles gets), ANYONE who has had chicken pox, no matter
how mild a case, can get shingles (shingles are caused by the same virus that causes chicken pox and once you've had chicken pox, teh virus remains in your body forever).
The likelihood of shingles is also higher if the rash is pretty much only on one side of her body rather than all over the body.
