Sexually transmitted infections (STIs)

Introduction

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 and 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 and how to prevent STIs.

What is a sexually transmitted infection (STI)?

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.

Where can I get an STI test in Ireland?

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

How to take a free home STI test

You will find instructions on how to take the STI test kit 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.
