Syphilis in Korea – Symptoms, Stages, and Safe Treatment Options
Syphilis is a serious but treatable sexually transmitted infection (STI) that’s on the rise in Korea. Caused by the bacterium Treponema pallidum, syphilis spreads through unprotected sexual contact and can lead to severe complications if left untreated. The good news? Early detection and antibiotic treatment can cure it completely.

What Is Syphilis?
Syphilis progresses in four stages, each with different symptoms:
- Primary Stage – A painless sore (chancre) appears where the infection entered the body, usually on the genitals, mouth, or rectum.
- Secondary Stage – Skin rashes (often on the palms or soles), fever, sore throat, and swollen lymph nodes may occur.
- Latent Stage – No symptoms, but the bacteria remain in the body and can be detected through blood tests.
- Tertiary Stage – If untreated, it can damage the heart, brain, nerves, and other organs—sometimes years after infection.
How Is Syphilis Spread?
- Vaginal, anal, or oral sex
- Direct contact with a syphilis sore
- From mother to baby during pregnancy (congenital syphilis)
You can get or spread syphilis even if you or your partner don’t show visible symptoms.
Syphilis Testing in Korea
Testing is done through a simple blood test and is widely available at:
- Urology clinics
- Public health centers
- International clinics in areas like Gangnam or Itaewon
Many clinics offer same-day testing and results within 1–2 business days.
Syphilis Treatment in Korea
Syphilis is treated with antibiotics, most commonly:
- Penicillin G benzathine injection
- For penicillin-allergic patients: doxycycline or other alternatives
One injection may be enough in early stages. Late-stage or latent syphilis may require multiple doses over several weeks.
Why You Shouldn’t Delay Treatment
Untreated syphilis can lead to:
- Neurological and heart complications
- Organ failure
- Blindness
- Stillbirth or severe birth defects (if pregnant)
Prompt treatment not only cures the infection but also prevents long-term damage and transmission to others.
