A small, painless spot that fades on its own after a few weeks: with syphilis that is often the moment people decide it is nothing serious. The opposite is true. The sore disappears, but the infection stays, and can quietly continue. Precisely because the first sign looks so harmless, syphilis is easily missed.
Our stance: with syphilis, "it went away by itself" is not reassurance but a warning. A sore disappearing does not mean the infection is gone.
The stages of syphilis
Syphilis classically runs in phases that flow into one another. RIVM describes an early and a late phase, with complaint-free periods in between. That symptom-free interval is treacherous: it feels like recovery, while the bacteria remain present. The overview below shows the stages as a guide, not a diagnosis.
| Stage | Roughly when | Possible signs |
|---|---|---|
| First (primary) | Approx. 3 weeks after contact | A painless sore at the site of infection, fades on its own |
| Second (secondary) | Weeks to months later | Skin rash (often hands/feet too), flu-like feeling, swollen glands |
| Latent | Months to years | No complaints, infection still present |
| Late | Years later, rare | Possible damage to organs or nervous system |
The late phase is rare in the Netherlands, precisely because syphilis is well treatable when caught in time. The signs per phase can also belong to other conditions, so they prove nothing on their own.
Why the sore puts you on the wrong track
The first sore is usually painless and sometimes sits in a place you cannot see well, such as inside the vagina, the anus or the mouth. So you do not always notice it. Its fading away feels like relief, but it says nothing about whether the bacteria are still present. A test is the only way to establish that.
How is syphilis tested?
Syphilis is detected with a blood test that tracks antibodies against the bacteria. You can go to your GP, a sexual-health clinic or use a test you take at home. If you want to keep it discreet, a syphilis test via a blood sample can be convenient. Because syphilis and HIV can increase each other's risk, getting checked at the same time is often advised; an HIV test then belongs to the same consideration.
An important point about the waiting time: a syphilis test is usually only reliable from around 6 weeks after contact, and certainty often comes around 12 weeks. If you test earlier, the result can be false negative. Read more in how long after sex you can test. Another point of attention: after a past syphilis infection, antibodies can stay detectable in your blood for a long time. So a doctor looks not only at whether antibodies are present, but also at their level, to tell an old infection from a new one. That is one reason you best review a result together with a doctor rather than interpret it yourself.
Why syphilis is becoming more common again
Syphilis seemed rare for a long time, but RIVM has seen a rise again in recent years, especially in certain groups. That makes the topic relevant again, also for people who never thought about it before. Our view on this is clear: syphilis simply belongs in a complete check, certainly if you also test for HIV, because the two can reinforce each other's risk. Anyone who only tests for chlamydia and gonorrhoea and skips syphilis misses an infection that is precisely well treatable in an early stage.
If you are structurally at higher risk, for example with changing partners, periodic testing can be wise. How often that fits you is tailored to you and is fine to discuss with a doctor or a sexual-health clinic.
And if the test is positive?
Syphilis is well treatable, usually with penicillin via a doctor. Thuisarts.nl and Soa Aids Nederland stress that timely treatment almost always prevents further problems. So you always discuss a positive result with your GP, who can also advise on testing your partner. What to do after a positive result is in positive STI result: what now.
With syphilis: do not let a fading sore reassure you. Every result we provide is assessed by a BIG-registered doctor, and you make treatment decisions together with your GP.
