Threadworms are thin, cotton-like worms usually between 2 and 12 mm in length. You may notice them in your or your child's poo after a bowel movement. However, sometimes the only symptom of an infection is itching around the back passage (anus) which occurs more frequently at night. If you suspect you or your child are suffering from threadworms, ask your doctor or pharmacist for advice.
