Syphilis in Denmark 2023: An in -depth status
Syphilis is a sexually transmitted infection that continues to pose a public health challenge in Denmark. According to the Statens Serum Institut (SSI), 649 cases of syphilis were recorded in 2023, marking a persistently high incidence of the disease in the country.
Increase among heterosexuals
While men who have sex with men (MSM) still account for a significant proportion of syphilis cases (66%), a worrying increase has been observed among heterosexual transmissions. In 2023, this group accounted for 30% of cases, up from 27% in 2022.
Geographical distribution and sources of infection
The vast majority of syphilis cases in 2023 were acquired in Denmark (88%). Among foreign sources of infection, Germany, Thailand, Spain, and the USA were the most common countries.
Syphilis and HIV
There were 110 reported cases where patients with syphilis were also HIV-positive. Of these, seven were newly diagnosed, including six MSM and one trans woman. This underscores the importance of regular testing for both infections in high-risk groups.
Syphilis among pregnant women
In 2023, ten cases of syphilis in pregnant women were identified through screening programmes. Of these, two were not reported, indicating a need for increased attention to correct reporting and follow-up.
Prevention and education
To reduce the number of syphilis cases, it is crucial to increase awareness about safe sex, regular testing and early treatment. Health authorities encourage people in risk groups to get tested regularly and to seek treatment if they suspect infection.
