Mostly in big cities
Most of the infected people live in large Danish cities.
For instance, in Copenhagen 64 out of 100,000 were infected with gonorrhea in 2014, while only five people got the disease on Bornholm.
Meanwhile, five times as many people in eastern Jutland were infected with syphilis compared to North Zealand.
Still, some people never learn to practice safe sex.
According to figures from Statens Serum Institut, 37 Danes were diagnosed with gonorrhea several times in 2014 and six of them were treated for the disease three times.
