The notification rate for sexually transmitted infections (STIs) in Ireland fell 11% in 2024, according to the Health Protection Surveillance Centre (HPSC). Figures released this week show the drop was mainly due to big reductions in chlamydia and gonorrhoea. However, that follows significant increases in notifications of both STIs in 2022 and 2023. Figures show that younger people are more affected by STIs, notably women aged 20-24 years. Cases in men are spread over a wider age range.
