Some worm infections can be caught in the UK and others are only caught abroad. Most worm infections are not serious and can be treated with medicine.
Worm infections are treated with medicine that you take for 1 to 3 days. The people you live with may also need to be treated.
You can get a worm infection by touching objects or surfaces with worm eggs on them, or swallowing water or food containing worm eggs.
To prevent worm infections, wash your hands before preparing food or eating, and after going to toilet. Drink bottled water in high-risk areas.
