RIVM Report 2015-0041
The number of people who got tested for a sexually transmitted infection (STI) at a Dutch STI clinic increased further in 2014. In addition, the percentage of consultations resulting in an STI diagnosis increased slightly to 15.5 per cent in 2014. General practitioners, who carry out the majority of STI consultations in the Netherlands, report a similar upward trend. As in previous years, chlamydia was the most frequently diagnosed STI. STI clinics offer free STI testing to high-risk groups and provide care and treatment if an STI is diagnosed. The total number of STI clinic consultations in 2014 was 141,191, an increase of 6 per cent compared to 2013. In 2014, STI clinic attendees who were diagnosed with an STI were mainly people who had been warned of possible STI exposure by their (former) partner, and known HIV-positive men who have sex with men (MSM). Chlamydia In 2014, 12.6 per cent of STI clinic attendees had a chlamydia infection (17,753 diagnoses). This figure represents an increase of 0.8 percentage points compared to 2013. The greatest increase was observed in heterosexual men (from 12.8 per cent in 2013 to 13.9 per cent in 2014). Chlamydia was primarily diagnosed in women and in heterosexual men below 25 years of age (15.6 per cent diagnosed with chlamydia). The percentage of MSM diagnosed with chlamydia has remained stable for years at around 10 per cent. Gonorrhoea The percentage of STI clinic attendees with a gonorrhoea infection has remained stable since 2012, and amounted to 3.6 per cent in 2014 with a total of 4,594 diagnoses. Gonorrhoea is over four times more common in MSM than in women and heterosexual men. Increased resistance to the antibiotics prescribed to treat gonorrhoea infections has been observed in several European countries, but not yet in the Netherlands. It remains important to closely monitor antibiotic resistance. Syphilis Syphilis was mainly diagnosed among MSM, who accounted for 93 per cent of the 742 cases diagnosed at STI clinics in 2014. The percentage of MSM with a syphilis infection increased from 2.0 per cent in 2013 to 2.3 per cent in 2014. The greatest rise was observed in known HIV-positive MSM: from 5.8 per cent in 2013 to 6.6 per cent in 2014. Of all MSM with syphilis, 41 per cent were known HIV-positives. HIV In 2014, the number of people newly diagnosed with HIV at STI clinics decreased by 9 per cent (from 358 cases in 2013 to 323 in 2014). MSM accounted for nearly 90 per cent of this group. The percentage of new HIV diagnoses in MSM decreased from 3.0 per cent in 2008 to 1.1 per cent in 2014. The number of new HIV diagnoses at Dutch HIV treatment centres also declined (from 1,311 in 2008 to 992 in 2013).
