Record-High STI Rates Across Europe Demand Urgent Public Health Response

As we navigate the mid-point of 2026, the public health landscape in Europe faces a significant and concerning challenge. New data released by the European Centre for Disease Prevention and Control (ECDC) reveals that sexually transmitted infections (STIs) reached record levels across the continent throughout 2024. This surge, characterized primarily by sharp increases in gonorrhoea and syphilis, highlights critical gaps in current testing, prevention and public health infrastructure.

For those of us working in clinical medicine and public health, these figures are more than just statistics—they represent a growing burden of disease that, if left unaddressed, carries the potential for severe, long-term health complications. The ECDC’s latest Annual Epidemiological Reports indicate that the transmission of these bacterial infections has been sustained across multiple nations for over a decade, with 2024 marking a particularly troubling peak.

The Data: A Decade of Rising Transmission

The numbers provided by the ECDC offer a stark look at the trajectory of bacterial STIs in Europe. Gonorrhoea, in particular, has seen a dramatic climb. In 2024, there were 106,331 reported cases, representing a 303% increase since 2015. Syphilis has similarly seen a rapid rise, with cases more than doubling over the same period to reach 45,577.

While chlamydia remains the most frequently reported bacterial STI in the region, with 213,443 cases recorded, it is the rapid acceleration of other infections that has drawn the most intense scrutiny from health authorities. The ECDC reported 3,490 cases of lymphogranuloma venereum (LGV), an infection that continues to see ongoing transmission across European borders.

The impact of this trend is not uniform. The data suggests that men who have sex with men remain the most disproportionately affected group, showing the most significant long-term increases in both gonorrhoea and syphilis. Simultaneously, public health officials have noted substantial increases in syphilis among heterosexual women of reproductive age, a development that carries profound implications for maternal and neonatal health.

The Growing Crisis of Congenital Syphilis

Perhaps the most distressing finding in the 2024 report is the near-doubling of congenital syphilis cases between 2023 and 2024. Congenital syphilis occurs when a mother passes the infection directly to her newborn, which can lead to potentially lifelong complications for the child.

Bruno Ciancio, Head of the ECDC’s Directly Transmitted and Vaccine-Preventable Diseases unit, emphasized the severity of the situation. “Sexually transmitted infections have been on the rise for 10 years and reached record high levels in 2024,” Ciancio noted. “Untreated, these infections can cause severe complications, such as chronic pain and infertility and, in the case of syphilis, problems with the heart or nervous system.”

Addressing the Prevention Gap

The ECDC has called for urgent, targeted action to stem the tide of these infections. The agency points to “widening gaps in testing and prevention” as a primary driver for the surge. In a clinical setting, we often see that the path to better outcomes is through accessible, non-judgmental care and consistent screening protocols.

From a public health perspective, the recommendations remain consistent but essential. Protecting sexual health is straightforward: the use of condoms with new or multiple partners remains a highly effective barrier against transmission. Regular testing is critical, particularly for those who experience symptoms such as pain, discharge, or the appearance of an ulcer. Early diagnosis allows for prompt treatment, which is the only way to prevent the progression of these diseases toward chronic or systemic damage.

Key Takeaways for Public Health

• Record Peaks: Gonorrhoea and syphilis reached their highest levels in over a decade during 2024.
• Congenital Risks: There has been a near-doubling of congenital syphilis cases, posing a significant risk to newborns.
• Targeted Demographics: While men who have sex with men remain the most affected, there is a notable rise in syphilis among heterosexual women of reproductive age.
• Prevention: Consistent condom use and proactive, regular STI testing are the primary tools for curbing the spread of these infections.

Moving Forward

The rise in STIs is a multi-faceted problem that requires a coordinated response from healthcare providers, policymakers, and the public. As we monitor the situation, the focus must remain on increasing the availability of testing services and ensuring that those who test positive receive the necessary clinical intervention without delay.

While the United Kingdom is no longer part of the ECDC reporting framework following Brexit, the data from the participating European countries provides a clear signal that the current strategy for STI prevention requires immediate refinement. Addressing these gaps is not merely a matter of healthcare policy, but a fundamental necessity for protecting the health of the population at large.

We will continue to follow updates from the ECDC as they release further analysis and guidance on managing these outbreaks. If you have questions about your own sexual health or need information on local testing facilities, I encourage you to reach out to your primary care physician or local sexual health clinic for guidance tailored to your specific needs.
