Chlamydia, gonorrhoea and syphilis are curable with antibiotics. HIV and hepatitis B are not curable, but are well controlled with medication. Treating early prevents complications and further transmission.
Right after a positive result
- Start the prescribed treatment and always finish an antibiotic course completely.
- Have no (unprotected) sex for seven days after starting treatment — after that you can no longer pass on the STI.
- Still want sex in that window? Then use a condom.
Partner notification: how and how far back
You notify sexual partners so they can get tested and treated. How far back you go depends on the STI: chlamydia roughly six months, gonorrhoea three months (or from your symptoms), syphilis and HIV longer. In the Netherlands there are three ways to do it.
- Tell them yourself — often the fastest and most personal.
- Anonymously via partnerwaarschuwing.nl: your GP or GGD gives you a code to send an anonymous message.
- Via the GGD, which notifies partners for you with your consent — common for HIV and syphilis.
Should partners be tested or treated?
For a recent contact (within about two weeks) a partner can sometimes be treated straight away, without waiting for a result first. For chlamydia, steady partners are often tested and treated at the same time to prevent reinfection.
Re-testing and follow-up
A test of cure is usually unnecessary after standard treatment, but is advised for throat gonorrhoea, in pregnancy or with persistent symptoms. Because reinfection is common, it is wise to re-test after about three to six months — especially if a partner was not treated.
HIV, syphilis and hepatitis
HIV leads to referral to an HIV treatment centre. Syphilis is treated by the GGD or a dermatologist, with blood checks at 3, 6 and 12 months. Hepatitis B and C lead to referral for vaccination and/or treatment.
