Dont get rid of her- just keep her clean and give her maintenance dewormer.
Check out the pet forum here at Curezone. -- A woman found this natural dewormer online that she uses on her cats that works. It is odorless and tastless. People can use it too. Animals dont necessarily care for the herbs in their food -so you may want to try that.
It was rather cheap too at $6.99 a bottle. I have to go back to the old posts to get you the link.
The other rules to follow with pets is to wash your hands after petting them, dont let them lick your face , and give them a comfy area to sleep nearby but not right on your bed.
Vaccuum pet hair regularly- even if you have to keep a scarf around your nose when doing this.
Make sure they poop away from the yard where no kids can be in contact with the feces-- or else use a "pooper scooper" and transport it away into a barren field area or garbage.
And most importantly show them love- its' not their fault they were brought into this World.
