STI Cases Surge in Ireland: A Growing Public Health Concern
Ireland is witnessing a significant rise in sexually transmitted infections (STIs), with health officials warning of an alarming increase in cases across all age groups. According to the Health Protection Surveillance Centre (HPSC), STI rates in 2023 rose by 31% compared to the previous year, sparking renewed calls for increased awareness, testing, and prevention strategies.

STI Cases in Ireland: The Latest Figures
Recent data from the HPSC highlights a worrying trend:
- Overall STI notification rates: Increased by 31% in 2023, reaching 452 cases per 100,000 people, up from 346 per 100,000 in 2022.
- Chlamydia: The most common STI, with 13,541 cases in 2023, marking a 25% increase from the previous year. Over half (52%) of cases were in 15-24-year-olds.
- Gonorrhoea: Experienced a 68% rise, with 6,824 cases reported in 2023. Alarmingly, cases among females aged 15-19 surged by 175%.
- Genital Herpes: Recorded 313 cases in early 2024, reflecting a 13.8% rise from the same period last year.
- Syphilis: Cases have jumped 46.6% in 2024, with 198 infections reported in the first nine weeks of the year.
These figures indicate a sharp and consistent rise in STI infections, particularly among younger individuals.

Why Are STI Rates Rising in Ireland?
Several factors are contributing to the surge in STI cases across the country:
1. Increased Testing and Awareness
- More people are getting regular sexual health check-ups, leading to higher detection rates.
- Free STI home testing kits and greater availability of sexual health clinics have made testing more accessible.
2. Changes in Sexual Behaviour
- More casual relationships and less consistent condom use have been linked to the rising STI figures.
- Apps and online dating have made sexual encounters more frequent, increasing the risk of transmission.
3. Post-Pandemic Social Reconnection
- After pandemic-related restrictions eased, there was a reported increase in sexual activity, leading to higher STI transmissions.
- Health officials believe this “post-lockdown effect” is still contributing to increased case numbers.
4. Lack of Comprehensive Sex Education
- Experts argue that Ireland’s sex education system remains outdated, failing to provide young people with proper knowledge about STI risks, prevention, and safe sex practices.

Who Is Most Affected?
1. Young People (15-24 Age Group)
- Over half of all chlamydia cases in 2023 were reported in people aged 15-24.
- Young women, particularly teenagers aged 15-19, saw the largest rise in gonorrhoea infections (175% increase).
2. Men Who Have Sex with Men (MSM)
- Health officials note that syphilis and gonorrhoea rates are rising at a faster rate among MSM populations.
3. Urban Areas Seeing Higher Infections
- Dublin, Cork, and Galway continue to report the highest STI cases, likely due to larger populations, nightlife, and increased social interactions.
Public Health Response: What’s Being Done?
1. More Free STI Testing Services
- Ireland has expanded free online STI home testing kits, making it easier for people to test discreetly and quickly.
- More public sexual health clinics are being set up in major cities and university areas.
2. Awareness Campaigns
- The HSE is launching new public health campaigns to promote safer sex and regular testing.
- Social media and university outreach programs aim to educate younger audiences on STI risks.
3. Calls for Improved Sex Education
- Many experts are pushing for better sexual health education in Irish schools, arguing that early education on STI prevention is key.

How to Protect Yourself Against STIs
✔ Use Condoms & Protection – Consistently using condoms can prevent most STIs, including chlamydia and gonorrhoea.
✔ Get Tested Regularly – Routine STI screenings (every 3-6 months) are recommended, especially for sexually active individuals with multiple partners.
✔ Be Open with Partners – Honest conversations about STI status and safe practices can help reduce risk.
✔ Get Vaccinated – The HPV vaccine is available for both men and women in Ireland and can prevent certain types of STIs, including genital warts and cervical cancer.
✔ Know the Symptoms – Some STIs show no immediate symptoms, so regular testing is the only way to be sure of your status.
Final Thoughts
The rise in STI cases in Ireland is a serious public health concern, particularly among young people. While increased awareness and testing have led to more reported cases, the underlying issue of risky sexual behaviour and lack of education needs to be addressed.
By promoting safe sex, expanding free testing, and improving sexual health education, Ireland can work towards reducing STI rates and protecting public health.
If you’re sexually active, it’s essential to get tested regularly, use protection, and stay informed about the risks of STIs.
