Europe’s bacterial sexually transmitted infections (STIs) reached record levels in 2024, with gonorrhea cases surging 303% since 2015 and syphilis cases more than doubling, according to the European Centre for Disease Prevention and Control (ECDC). The data, released by the agency based in Solna, Sweden, highlights a decade-long public health crisis exacerbated by behavioral shifts, testing gaps, and systemic challenges in prevention and treatment Yahoo.
Rise in Cases and Data Insights
The ECDC reported 106,331 gonorrhea cases in 2024, a stark increase from 2015, while syphilis cases rose to 45,577, more than double the 2015 total. Chlamydia remained the most frequently reported STI, with 213,443 cases, underscoring persistent challenges in asymptomatic infections. Congenital syphilis, where the infection passes from mother to child, nearly doubled from 78 cases in 2023 to 140 in 2024 across 14 countries The Independent.
“Sexually transmitted infections have been on the rise for 10 years and reached record high levels in 2024,” said Bruno Ciancio, head of the ECDC’s directly transmitted and vaccine-preventable diseases unit. “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” The Independent.
Epidemiological Patterns and Risk Factors
Men who have sex with men (MSM) are disproportionately affected, with the sharpest long-term increases in gonorrhea and syphilis. However, syphilis is also rising among heterosexual populations, particularly women of childbearing age, driving the surge in congenital cases. The ECDC noted “ongoing transmission” of lymphogranuloma venereum (LGV), a rare chlamydia strain, with 3,490 reported cases in 2024 Bioengineer.org.
“Protecting your sexual health remains straightforward,” Ciancio advised. “Use condoms with new or multiple partners, and get tested if you have symptoms, such as pain, discharge or an ulcer” Yahoo. The agency emphasized that untreated infections can lead to “potentially lifelong complications,” including heart and nervous system damage from syphilis and infertility from gonorrhea.
Drivers of the STI Surge
The ECDC attributed the rise to evolving sexual habits, gaps in testing, and structural barriers to care. “The drivers of this STI resurgence are intricately linked to evolving behavioral, social, and systemic factors,” the agency stated. For MSM, long-term increases reflect persistent transmission patterns, while heterosexual syphilis growth highlights missed opportunities in prenatal screening and treatment Bioengineer.org.
“Congenital syphilis, stemming from insufficient maternal screening and treatment, exposes newborns to devastating lifelong disabilities or death,” the report warned. This underscores the need for improved antenatal care and access to testing, particularly in regions with limited healthcare infrastructure The Independent.
Call for Tailored Interventions
Experts stress the urgency of targeted strategies to address disparities in infection rates. “The heterogeneity of the epidemic demands interventions specific to sexual orientation, gender, and age strata,” the ECDC noted. Public health campaigns must prioritize education on condom use, regular testing, and reducing stigma around seeking care.
“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,” Ciancio reiterated, calling for “more accessible testing” to curb transmission news.google.com. The agency also warned of the growing risk of antibiotic resistance, as gonorrhea strains show increasing resistance to standard treatments, complicating management efforts.
What Comes Next?
The ECDC has urged governments to invest in expanded testing programs, public awareness initiatives, and improved access to treatment. With congenital syphilis cases rising, maternal health services must be strengthened to ensure timely screening and intervention.
