Certain types of worms can infect people. You can get some types of worm infections in Ireland and other types abroad.
Most worm infections are not serious and can be easily treated with medicine.
A pharmacist can help with worm infections
A pharmacist can help if you have:
- small, white worms in your poo that look like pieces of thread
- extreme itching around your anus, particularly at night
These are probably threadworms. They're common in Ireland and can be treated with medicine from a pharmacy.
Non-urgent advice: Contact your GP if you:
- find a large worm or large piece of worm in your poo
- have a red, itchy worm-shaped rash on your skin
- have sickness, diarrhoea or a stomach ache for longer than 2 weeks
- are losing weight for no reason
These could be symptoms of something like roundworm, hookworm or tapeworm.
These infections are more likely to happen when travelling. They can take a long time to cause symptoms. Tell your GP if you have been abroad in the last 2 years.

Treating a worm infection
It does not matter which type of worm you have. All worm infections are treated in a similar way.
You might be asked to provide a sample of poo so it can be tested for worm eggs.
If you have worms, your GP will prescribe medicine to kill them. You take this for 1 to 3 days. The people you live with may also need to be treated.
Any worms in your gut will eventually pass out in your poo. You might not notice this.
To avoid becoming infected again or infecting others, it's very important during the weeks after starting treatment to wash your hands:
- after going to the toilet
- before eating or preparing food
- often during the day
Go back to your GP if:
- your symptoms do not get better in 2 weeks
- you keep passing live worms in your poo
How worms spread
Worms are mainly spread in small bits of poo from people with a worm infection. Some are spread through food.
You can get infected by:
- touching surfaces contaminated with worm eggs
- swallowing worm eggs in contaminated food or water
- walking barefoot on soil containing worms
- eating raw or undercooked beef, pork or freshwater fish containing worms
You can catch some worms from pets. But this is rare.
