Should I be worried about pinworms?

Possibly. Pinworms is the most common worm infection in the us -- and school-age kids are the ones who most commonly get it. They unknowingly touch the eggs, put fingers in mouths, and the eggs mature -- producing intense anal itching esp. @ night. The eggs can be transferred to others in the house also. See your family doctor for help if needed. Http://www. Ncbi. Nlm. Nih. Gov/pubmedhealth/pmh0002137/.
No. Pin worms are very easily treated. If you feel you have them, see your doctor for the treatment.
