What is it?

Syphilis is caused by the bacterium Treponema pallidum. It has different stages; a sore disappearing does not mean the infection has cleared.

How is it transmitted?

Through direct contact with an infectious sore during oral, anal or vaginal sex. It can also be passed to a fetus during pregnancy.

How is it not transmitted?

It is not transmitted through toilet seats, shared utensils or ordinary everyday contact.

What happens after exposure?

The bacterium enters through skin or a mucous membrane and can spread through the body. If you have had a confirmed exposure to early syphilis, see a clinician even if your test is negative.

Incubation period

The first sore usually appears around the third week, but the interval can be approximately 10–90 days. This is the time to symptoms, not the time to a reliable test.

Window period: when should I test?

Antibodies may be absent in the earliest stage. If you have a sore or a known exposure, testing starts now; a clinician decides when to repeat it based on the test, exposure date and previous treatment.

What are the symptoms?

A painless sore is common. Later symptoms can include a rash, including on the palms and soles, swollen lymph nodes and fatigue.

Can there be no symptoms?

Yes. A sore may be hidden, and the latent stage has no visible symptoms.

Which parts of the body can be affected?

The first changes may affect the genitals, mouth or anus. Syphilis is a systemic infection and can affect the nervous system, eyes and hearing.

How is it tested?

A treponemal test is combined with a nontreponemal test such as RPR/VDRL. Direct detection from a suitable lesion may also be used where available.

What sample is needed?

Usually blood. A sample from a sore is collected only when indicated and an appropriate laboratory method is available.

What does a positive result mean?

A single reactive test does not determine the stage. Some antibodies remain positive after successful treatment: bring your previous results too.

How is it treated?

Treatment uses an appropriate antibiotic, most often penicillin. The regimen depends on the stage, pregnancy and organ involvement; follow-up antibody titres are needed.

Can I acquire it again?

Yes. Having had syphilis does not provide reliable protection against a new infection.

What should partners know?

Partners should be referred for assessment. Recent exposure to early syphilis may require treatment even with a negative result.

How can I reduce the risk?

Condoms reduce the risk but do not cover every sore. Regular testing and timely treatment interrupt transmission.

When should I seek medical care?

If you have a sore or rash, or a partner has been diagnosed. New problems with vision or hearing, or neurological symptoms, require immediate assessment.

What should I do now?

Book a test and explain recent exposures and previous treatment. Do not delay medical assessment during pregnancy. See the current price list for available services and prices.

Does a positive test prove recent exposure?

No. Some tests remain reactive for years or for life. Your history and changes in RPR/VDRL help with interpretation.
