According to the Statens Serum Institut (SSI), Denmark registered 5,134 cases of gonorrhea, with 3,747 cases among men and 1,387 among women across 343,224 completed test episodes. While the overall volume remains on par with recent years, public health officials track a continuing rise among men who have sex with men alongside signs of stabilization among heterosexual populations.
Infection Demographics and Global Travel Links
Men accounted for 73% of all registered gonorrhea episodes in Denmark, marking a two-percentage-point increase from the previous year, according to the SSI annual report. Infection between two women was documented in 12 cases, up from eight cases previously. While standard diagnoses typically target urogenital, anorectal, and pharynx locations, healthcare providers also detected gonorrhea in 20 atypical sites, including eyes, synovial fluid, and blood.
Geographic tracking shows that travel plays a notable role in transmission. Information regarding the country of infection was available for 4,013 episodes, representing 78% of the total. Of those, 8%—or 338 cases—were acquired abroad across 53 different countries, down slightly from 10% in the prior year. Spain, Germany, Thailand, Sweden, and the United Kingdom accounted for the majority of these travel-related infections.
Comparative Infection Rates by Gender and Orientation
Data from the SSI report highlights differences in how travel impacts specific demographic groups. A higher proportion of gonorrhea episodes among men were acquired abroad at 10%, compared to 5% among women.
Did you know? In 2025, diagnostic testing in Denmark reached a massive scale with 343,224 completed test episodes, helping healthcare providers catch infections across both traditional and atypical anatomical locations.
Antibiotic Resistance and Ceftriaxone-Resistant Strains
Public health authorities are monitoring shifts in antibiotic resistance as gonorrhea bacteria continue adapting over time. While standard treatment in Denmark relies on the antibiotic ceftriaxone, international developments point toward growing therapeutic challenges. SSI reported finding ceftriaxone-resistant gonococci in two male patients who contracted the infection in Southeast Asia during 2025. A third case appeared in January 2026, also in a man infected in Southeast Asia, where resistant strains are primarily located in Cambodia and Vietnam.
All three patients displayed only a very low level of resistance, responded successfully to ceftriaxone treatment, and experienced no treatment failures, according to SSI findings. DNA analyses of the bacteria confirm that the three cases are genetically unrelated. Furthermore, surveillance has detected no further spread of these resistant strains within Denmark.
Pro tip: Healthcare professionals advising travelers to Southeast Asia should emphasize prevention and prompt testing, as international acquisition remains a primary vector for rare, resistant bacterial strains entering Europe.
Frequently Asked Questions
What is the primary treatment for gonorrhea in Denmark?
Gonorrhea is generally treated using the antibiotic ceftriaxone, according to SSI guidelines.
How common is ceftriaxone resistance in Denmark?
Resistance to ceftriaxone remains very rare. SSI detected only three cases between 2025 and January 2026, all involving individuals infected in Southeast Asia with no subsequent domestic spread.
Which countries account for most travel-acquired gonorrhea cases?
Spain, Germany, Thailand, Sweden, and the United Kingdom are the top countries where international cases reported by SSI are acquired.
