The number of people who got themselves tested for a sexually transmitted infection (STI) at a Sexual Health Centre (SHC)  in 2019  has remained almost the same as in 2018. The number of STI tests carried out by general practitioners (GPs) is increasing. There are fewer new HIV-positive diagnoses at the SHCs, but syphilis and gonorrhoea are increasing. Chlamydia remained the most common STI. This is according to RIVMNational Institute for Public Health and the Environment ’s annual report Sexually transmitted infections in the Netherlands 2019.

In 2019, more than 150,000 people were tested at the SHCs, more or less the same number as in 2018. Almost one in five people who get tested actually have an STI. GPs perform most STI-tests. For this group, the data from 2018 is used. In that year, GPs had 335,000 STI consultations, 8 per cent more than the previous year.

Chlamydia

Chlamydia has been the most common STI for years, especially among young people. In 2019, more than 21,000 SHC visitors were diagnosed with chlamydia, just as in 2018. Fifteen per cent of the women that are tested at an SHC are diagnosed with chlamydia. For heterosexual men this number is 18 per cent. For men who have sex with men (MSM), this percentage has remained stable at 10 per cent for many years. In 2018, the number of chlamydia diagnoses performed by GPs was 42,500; an increase of 7 per cent compared to 2017.

Gonorrhoea

More than 8,000 SHC visitors were diagnosed with gonorrhoea; an increase of 11 per cent compared to 2018. This STI is common among MSM. Since 2015, gonorrhoea is the most common STI in this group. The number of gonorrhoea diagnoses also increased at GP practices from 9,550 in 2017 to 11,300 in 2018. This increase was mainly observed among women under 25.

Syphilis

In 2019 the number of syphilis cases diagnosed by SHCs increased by 16.8 percent compared to 2018. In almost all cases, these infections were diagnosed amongMSM. Syphilis is rarely diagnosed in women and heterosexual men.

HIV

The number HIV diagnoses by SHCs declined sharply by 34 per cent in 2019. The SHCs diagnosed 27 per cent of the total HIV diagnoses, 152 diagnoses were among MSM and 12 diagnoses among heterosexual men. The number of people with HIV who came for treatment at one of the Dutch HIV treatment centres for the first time in 2019 was 972. In total, 20,724 people with HIV were registered ‘in treatment’ in 2019.

PrEP

In 2019, a national pilot programme made it possible for SHCs to give pre-Exposure Prophylaxis (PrEP) to people at high risk of an HIV infection. These are mainly men who have sex with men. PrEP is used to prevent an HIV infection. By the end of 2019, 2,800 people had their first PrEP consultation through this PrEP pilot programme at SHCs. A maximum of 6,500 people can participate.
