Worms aren’t fussy about who they infect

As threadworm is so contagious, they can spread easily in homes, schools, day-care centres, and other places where there are likely to be groups of people, especially children.

School-aged children are particularly susceptible to catching worms, as they often share things like food, pencils, books or toys. Any of these items can carry tiny, almost invisible worm eggs.

If one person in your family has a threadworm infection, then it’s likely that the rest of the family does too.
