Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. Its early signs —
a painless sore and later a rash — are easy to miss and go away on their own, but the infection stays in the body
and can damage the heart, brain, nerves and eyes years later. It can also pass to a baby during pregnancy. Syphilis
is simple to test for and is cured with penicillin injections.
How it spreads
Syphilis spreads through direct contact with a syphilis sore or rash during vaginal, anal or oral sex, and from a
mother to her baby during pregnancy. It is most infectious in the first two stages. It does not spread through
toilet seats, shared utensils, swimming pools or clothing. Having had syphilis before does not protect you from
getting it again.
Sexually transmitted infections are cured or controlled with the right tests and prescribed treatment. Partners need testing too, and consultations are confidential.
The stages
Treatment works at every stage, but damage already done in the tertiary stage may not reverse — early testing matters.
When to seek urgent care
Changes in vision, eye pain or redness with a known or possible syphilis infection
Severe headache, confusion, hearing loss, weakness or numbness
A sore or rash in pregnancy — see a doctor promptly
See a doctor for any sore or ulcer on the genitals, anus or mouth, even if it is painless and heals, and for an unexplained rash on the palms or soles.
Syphilis in pregnancy
Untreated syphilis in pregnancy can cause miscarriage, stillbirth, early birth, or a baby born with
congenital syphilis. Every pregnant woman should have a syphilis blood test at her first antenatal
visit — it is part of routine antenatal care and free at government facilities. Treatment with penicillin during
pregnancy protects the baby.
Testing & treatment
A blood test diagnoses syphilis; a swab from a sore can also be tested. Testing for HIV and other STIs is advised at
the same time. Treatment is with benzathine penicillin injections — a single dose for early syphilis,
or weekly doses for three weeks for later stages; other antibiotics are used if you are allergic to penicillin.
Avoid sex until treatment is complete and any sores have healed, and have follow-up blood tests to confirm the
treatment worked. Recent partners need testing and treatment too. Free, confidential testing and treatment are
available at government hospitals and designated STI clinics.
Prevention
Use condoms every time; note they protect only the area they cover.
Test regularly if you have new or multiple partners.
Get tested in early pregnancy — and again later if at ongoing risk.
Talk openly with partners about testing; tell partners if you are diagnosed so they can be treated.
Ayurveda & history
Penicillin cures syphilis; no herbal treatment does. Never use mercury-containing preparations.
Syphilis is not in the ancient Ayurvedic classics. It is described in the 16th-century Bhavaprakasha as
Phiranga roga — the “disease of the Firangis” — because it arrived with European traders. Historically it
was treated with mercury compounds (such as Rasakarpura), as it was in Europe. Mercury is toxic to the
kidneys, nerves and brain, and these preparations must not be used. Today, an Ayurvedic physician's role is limited
to general supportive care after penicillin treatment. Anyone who offers to cure an STI with herbs or “special
preparations” should be avoided.
