Dr Phil Kieran: What can we do to prevent return of worms?

"Worms are a very common condition in children. They most frequently are found when a child complains of an itchy bottom, particularly at night, and can be seen in their poo as moving, tiny, white, thread-like things."

My four-year-old grandson was recently treated for worms with over-the-counter medication. 

Thankfully, he made a quick and full recovery, and no one else in the family picked them up.
