Syphilis in Nepal
- Under-diagnosed — silent latent and vague secondary are frequently missed.
- Congenital risk — vertical transmission to fetus is serious and preventable.
- RPR-titer monitoring — the RPR guides treatment-response — correct algorithm matters.
- Co-infection — HIV and other STIs commonly co-tested.
Syphilis — the Staged, Curable STI
Syphilis (Treponema pallidum) is a **bacterial STI** that progresses through distinct stages — the **primary chancre** (the painless ulcer), the **secondary** (the rash + systemic), the **latent** (the silent, serologically-detected), and the **tertiary** (the cardiovascular/neurological damage, years later).
It's "the great imitator" — secondary rash and systemic signs mimic many diseases. The diagnosis is by the **treponemal + nontreponemal (RPR/VDRL) serology algorithm**, and treatment is **penicillin** — curative at every stage when correctly given.
The congenital transmission (to fetus) makes antenatal screening essential — a preventable but serious outcome. This page explains complete picture.
The Stages
Primary
The chancre — painless, indurated ulcer at inoculation site; heals even without treatment.
Secondary
The rash (incl. palms/soles) + systemic + mucous lesions — great-imitator stage.
Latent
The silent, serologically-detected stage — early latent and late latent.
Tertiary
The cardiovascular (aortitis), neurological (neurosyphilis), and gummatous damage — years later, preventable.
The Testing Algorithm
Treponemal test
The specific antitreponemal antibodies — screening/confirmation; remains positive for life after infection.
Nontreponemal RPR
The quantitative RPR/VDRL — indicates disease activity + titer monitors response.
Dual algorithm
The treponemal + nontreponemal correctly confirmed — correct diagnosis.
RPR-titer monitoring
The titer falls with treatment — correct follow-up.
The Penicillin Treatment
Penicillin
Benzathine penicillin G — curative agent for every stage; the single-dose for early, course for late.
Stage-matched
The correct dose-duration — early vs late vs neuro different regimens.
RPR-monitored
The titer followed serologically — cure confirmed.
Partner treated
The partner + abstinence prevents reinfection.
The Congenital Prevention
The untreated maternal syphilis transmits to fetus — congenital syphilis (stillbirth, neonatal death, or multi-system damage). The **antenatal RPR/serology screening is prevention** — a simple screen that prevents a devastating outcome.
We screen pregnant women + treat early + prevent transmission.

Frequently Asked Questions
What are stages of syphilis?
The primary (the chancre), secondary (the rash + systemic), latent (the silent), and tertiary (the cardiovascular/ neurological) — curable at every stage.
Is syphilis curable?
Yes — penicillin is curative at every stage. The early detection + correct regimen + the RPR follow-up.
What is RPR?
The nontreponemal serology — quantitative titer + disease-activity + monitors treatment-response.
Can it be passed to baby?
Yes — congenital transmission is serious + preventable. The antenatal screening + early treatment prevents it.
