Sexually transmitted infections (STIs)

Sexually transmitted infections (STIs) are very common. They can affect people of all ages and backgrounds. If you are worried about an STI, you can get information, help and treatment if you need it.

This page has information on sexual health, including sexually transmitted infections (STIs), how to get an STI test in Ireland and how to prevent STIs.

A sexually transmitted infection (STI) is an infection you can get if you have sexual activity with an infected person.

The HSE website sexualwellbeing.ie has information on sexual health and common STIs in Ireland such as chlamydia, syphilis, HIV and others.

If you are worried about an STI, you should visit your GP, pharmacist or an STI clinic for medical advice.

STIs do not always have symptoms. Untreated STIs can cause serious health problems so it is important to get tested regularly.

You should get an STI test if:

• You have any symptoms of an STI
• Your sexual partner has an STI
• You have a new sexual partner
• You have more than one sexual partner

Ordering a free STI test to your home

If you are aged over 17 and living in Ireland, you can order a free STI test online to take at home. If there are no more kits available to order, try again the following morning. Your STI test kit will arrive in a plain envelope that fits through letterboxes.

How to take a free home STI test

In the kit, you will find instructions on how to take the STI test and a stamped addressed envelope to post your completed test kit back to the lab. You will get your results by phone or text message within 72 hours of the samples arriving at the lab.

You can read frequently asked questions about the kit.

Getting tested at an STI clinic in Ireland

Some hospitals and clinics also offer free STI tests. Check where your closest STI test centre is located.

You can also get STI tests from many GPs, student health services or NGOs (for example HIV Ireland) but you may have to pay for your test.

You can read about what happens during an STI test and what happens if you test positive for an STI on the HSE website.

Using condoms reduces your risk of getting an STI. You can get free condoms from:

• Sexual health or GUM (genitourinary medicine) clinics
• Some sexual health NGOs
• Many third level colleges

You can buy condoms without a prescription from many supermarkets, newsagents and pharmacies in Ireland.

You can read about other ways to reduce your risk of getting an STI.

Vaccines to prevent STIs

Vaccines can prevent some infections that passed during sexual activity including the Human Papillomavirus (HPV) and Hepatitis A and B.

Some public STI clinics offer free vaccinations. These are generally available to people who may be at risk of contracting an infection through sexual transmission.

You can get more information about vaccination against infections that are sexually transmitted from the HSE.

HPV vaccine

The HPV vaccine protects against the HPV virus which can cause cancer in both men and women.

You can get the free HPV vaccine if you are in first year of secondary school. You will be offered a free vaccine in your school with the school vaccination programme or in a HSE clinic.

If your child is absent during the school vaccination or your child is home-schooled, contact your local health office about vaccination.

You can read more about the HPV vaccine on the HSE website.

You can find information in different languages about the school vaccination programme

Mpox (monkeypox vaccine)

Mpox spreads from person to person through very close contact. If you are a close contact of someone who has mpox, you will be contacted by health professionals.

The mpox vaccine is recommended for people who are in the risk groups listed on the HSE website.

You can read more about Monkeypox on the HSE website.
