Of all STIs, the increase in gonorrhea was greatest in 2022. With 10,600 diagnoses, this is an increase of 33% compared to 2021, when there were 7,964 cases. The number of women and heterosexual men with gonorrhea has increased sharply. Among women, the percentage of tests that were positive increased from 1.5% in 2021 to 2.3% in 2022, and among men that percentage rose from 1.8% to 2.4%. For women, this means the highest percentage since 2013. The increase was mainly seen in the second half of 2022. Among men who have sex with men ( MSM(men who have sex with men)) who do not participate in the PrEP(pre-exposure prophylaxis)pilot, the percentage increased slightly, from 12.4 to 12.8%. Among MSM who do participate in the PrEP pilot, the percentage went from 9.2 to 9.8%.
In 2022 there were 24,684 chlamydia diagnoses, an increase of 21% compared to 2021. The percentage of women with chlamydia was higher in 2022 than in 2021: it increased from 16.2 to 17.9%. The percentages of heterosexual men and MSM with chlamydia have decreased slightly to 21.2 and 10.9% respectively.
The number of syphilis diagnoses was also higher at 1,574 than in 2021, when there were 1,398. But a slight decrease in the percentage of positive tests was visible among MSM: from 2.6% in 2021 to 2.3% in 2022. Among MSM participating in the PrEP pilot, the percentage remained the same (1.7%). The number of diagnoses among women and heterosexual men remained low in 2022: 0.29% among heterosexual and 0.15% among women.
