Denmark became the first country in the European Union to eliminate mother-to-child transmission of HIV and syphilis.[1][2] The World Health Organization (WHO) certified it because the country met targets for 2021 to 2024, including low transmission rates and high coverage of prenatal testing and treatment for pregnant women.[1][2] Elimination means testing and treating at least 95 out of 100 pregnant women and keeping the number of new infections in infants below 50 per 100,000 births.[1][2][7] There are approximately 5,950 people living with HIV in Denmark, with pregnant women accounting for less than 0.1 percent of cases.[1][2] Congenital syphilis is rare; in 2024, 626 cases were reported, of which 524 were in men.[1][2] Denmark has a low incidence of HIV and syphilis in pregnant women.[1][2] The WHO reported that Denmark is on track to eliminate mother-to-child transmission of hepatitis B.[1][2]
