Syphilis in women can be difficult to recognize because the infection may cause mild symptoms—or no symptoms at all. The first sign is often a painless genital sore, but the sore may occur inside the vagina, on the cervix, around the anus, or in the mouth and therefore go unnoticed. Later, syphilis may cause a rash, swollen lymph nodes, fever, or other symptoms before entering a latent stage with no visible signs.
Because untreated syphilis can persist for years and cause serious complications, testing matters even when symptoms have disappeared.
At Gynae Clinic Pvt. Ltd., Bode Planning, Madhyapur Thimi-9, Bhaktapur, women can receive confidential STI evaluation, syphilis testing, Gynecologist consultation, and Venerologist consultation.
What Is Syphilis?
Syphilis is a bacterial sexually transmitted infection (STI) caused by Treponema pallidum.
It can be transmitted through sexual contact with an infectious lesion during:
- Vaginal sex
- Anal sex
- Oral sex
Syphilis can also be transmitted from a pregnant woman to her fetus.
Unlike some vaginal infections that primarily cause discharge or itching, syphilis may initially produce a small, painless sore that is easy to miss.
This is one reason why relying only on symptoms can be dangerous.
Early Syphilis Symptoms in Women
1. A Painless Genital Sore
The classic early symptom of syphilis is a chancre—usually a painless, firm, round sore at the site where the infection entered the body.
In women, it may occur on:
- Vulva
- Vagina
- Cervix
- Around the anus
- Rectum
- Mouth
- Throat
Because a vaginal or cervical sore may not be visible, some women never realize that they have had the first sign of syphilis.
Important:
A painless sore does not mean the infection is harmless.
The sore can heal without treatment, but the infection can remain and progress to another stage.
2. Swollen Lymph Nodes
Some women with early syphilis may develop swollen lymph nodes, particularly near the area of infection.
For example, enlarged groin lymph nodes may occur with a genital infection.
3. Secondary Syphilis: Skin Rash
If primary syphilis is not treated, it can progress to secondary syphilis.
A characteristic symptom is a non-itchy rash, which can involve:
- Trunk
- Arms
- Legs
- Palms of the hands
- Soles of the feet
The rash can be subtle and may resemble other skin conditions.
A rash on the palms and soles deserves medical attention
A rash in these areas is not automatically syphilis, but when combined with a possible STI exposure or other symptoms, it should be evaluated.
4. Fever and Flu-Like Symptoms
Secondary syphilis can produce symptoms such as:
- Fever
- Fatigue
- Headache
- Sore throat
- Muscle aches
- Swollen lymph nodes
These symptoms are nonspecific and can easily be mistaken for another illness.
5. Genital or Anal Lesions
Secondary syphilis can produce raised or moist lesions in warm, moist areas such as the labia or around the anus.
Any unexplained genital or anal lesion should be professionally evaluated.
Can Syphilis Have No Symptoms?
Absolutely.
Many people with syphilis do not notice symptoms, and the infection can enter a latent stage in which there are no visible clinical signs.
This is one of the strongest reasons to consider testing after a meaningful exposure.
Remember:
No symptoms does not necessarily mean no syphilis.
Waiting for a sore or rash can allow an infection to remain undiagnosed.
Why Syphilis Testing Matters
Syphilis testing is important because:
Symptoms may be absent
A woman can have syphilis without knowing it.
Early symptoms may disappear
A chancre can heal without treatment, creating a false impression that the problem has resolved.
Symptoms can resemble other conditions
A rash, swollen lymph nodes, or genital lesion can have many causes.
Untreated infection can progress
Syphilis can remain in the body for years and may eventually cause neurological, cardiovascular, and other complications.
It can affect pregnancy
Untreated maternal syphilis can cause severe pregnancy and newborn complications, including congenital syphilis.
Who Should Consider a Syphilis Test?
A woman should discuss syphilis testing with a healthcare professional if she has:
- A new sexual partner
- Unprotected sexual contact
- A partner diagnosed with syphilis
- A partner diagnosed with another STI
- A possible STI exposure
- An unexplained genital sore
- A painless genital ulcer
- An unexplained rash
- A rash involving the palms or soles
- Swollen groin lymph nodes
- Unexplained genital or anal lesions
- Other symptoms suggesting an STI
Testing should be individualized according to the person’s sexual history, symptoms, pregnancy status, and exposure.
Syphilis Testing in Women
Syphilis is usually diagnosed using a combination of:
Medical history + physical examination + blood testing
WHO notes that serological testing is commonly used for syphilis diagnosis.
Common blood tests include:
RPR
Rapid Plasma Reagin (RPR) is a non-treponemal test.
It can be useful for:
- Supporting diagnosis
- Assessing disease activity
- Establishing a baseline
- Monitoring response to treatment
VDRL
Venereal Disease Research Laboratory (VDRL) is another non-treponemal test used in syphilis evaluation.
TPHA / TPPA
These are treponemal tests that detect antibodies associated with Treponema pallidum.
Rapid Syphilis Tests
Rapid tests are also available in many settings and can provide results quickly, helping facilitate prompt treatment when indicated.
Why Your Doctor May Recommend More Than One Syphilis Test
Syphilis testing can be more complicated than a simple positive-or-negative result.
Treponemal and non-treponemal tests provide different information, and interpretation depends on factors such as:
- Current symptoms
- Timing of possible exposure
- Previous syphilis infection
- Previous treatment
- Current test results
- Stage of infection
WHO recommends appropriate serological testing strategies, including non-treponemal testing such as RPR when available for identifying active infection and monitoring treatment response.
Your doctor should interpret your results in clinical context.
Can Syphilis Testing Be Negative After Recent Exposure?
Yes.
If testing occurs very early after infection, antibodies may not yet be detectable.
Therefore, a negative result does not always exclude a very recent infection.
If there is a strong clinical concern or recent exposure, your doctor may recommend repeat testing after an appropriate interval.
Syphilis and Pregnancy: Why Testing Is Extremely Important
Syphilis during pregnancy deserves special attention.
The infection can pass from the mother to the fetus and cause congenital syphilis.
Possible adverse outcomes include:
- Stillbirth
- Newborn death
- Prematurity
- Low birth weight
- Congenital infection
WHO estimates that untreated, inadequately treated, or late-treated maternal syphilis results in adverse birth outcomes in a substantial proportion of affected pregnancies.
WHO recommends testing pregnant women
WHO recommends that all pregnant women be tested for syphilis at least once and as early as possible, ideally at the first antenatal visit.
Early diagnosis and appropriate treatment can dramatically reduce the risk of congenital syphilis.
Is Syphilis Curable?
Yes. Syphilis is a curable bacterial infection.
The recommended treatment depends on the stage and clinical circumstances.
Benzathine penicillin G is the standard first-line treatment for many forms of syphilis, with the number of doses depending on the stage of infection. WHO identifies benzathine penicillin as the first-line treatment and the only WHO-recommended treatment for pregnant women with syphilis.
Do not self-treat syphilis.
Treatment should be prescribed by a qualified healthcare professional after appropriate evaluation.
Syphilis Treatment in Women
Treatment may vary depending on whether the infection is:
- Primary syphilis
- Secondary syphilis
- Early latent syphilis
- Late latent syphilis
- Syphilis of unknown duration
- Neurosyphilis
- Ocular syphilis
Therefore, one treatment schedule does not apply to every patient.
Your doctor will determine the appropriate treatment based on the stage and clinical findings.
What Happens After Treatment?
Treatment is only one part of syphilis care.
Your doctor may recommend follow-up testing to assess the response to treatment.
Non-treponemal tests such as RPR or VDRL can be useful for monitoring changes over time.
Follow-up is particularly important when:
- The infection was diagnosed at a later stage
- The initial test level was high
- Symptoms persist
- Pregnancy is involved
- Reinfection is possible
Can Syphilis Come Back?
A successfully treated infection can be cured, but treatment does not provide immunity against future infection.
A woman can become infected again following a new exposure.
This is why prevention, appropriate partner management, and repeat testing when indicated are important.
Should Sexual Partners Be Tested?
Yes, when appropriate.
If a woman is diagnosed with syphilis, her sexual partners may need evaluation, testing, and treatment depending on the timing and nature of their exposure.
Partner services are an important component of STI management because they help reduce ongoing transmission and reinfection.
Syphilis and Other STIs
A person can have more than one STI at the same time.
Depending on the history and symptoms, a doctor may recommend testing for:
- HIV
- Chlamydia
- Gonorrhea
- Hepatitis B
- Other STIs when clinically appropriate
WHO notes that STI symptoms are often nonspecific and recommends appropriate laboratory testing where available.
Syphilis vs Herpes: What Is the Difference?
Both infections can cause genital sores, but their typical presentations are different.
| Feature | Syphilis | Genital Herpes |
|---|---|---|
| Typical early lesion | Often a painless chancre | Often painful blisters/ulcers |
| Cause | Bacterium | Virus |
| Can become latent | Yes | Yes |
| Curable | Yes | No cure, but manageable |
| Testing | Blood tests commonly used | Testing depends on presentation |
| Treatment | Antibiotics | Antiviral medication |
Never diagnose a genital sore based only on appearance.
Syphilis vs Vaginal Infection
Syphilis is different from common vaginal conditions such as:
- Yeast infection
- Bacterial vaginosis
- Trichomoniasis
These conditions can cause discharge, itching, odor, or irritation, whereas early syphilis more classically presents with a painless ulcer.
However, symptoms can overlap and more than one infection can occur.
If you are unsure, testing is better than guessing.
When Should You See a Gynecologist or Venerologist?
Book a professional evaluation if you have:
- A painless genital sore
- Any unexplained genital ulcer
- Genital or anal lesions
- A rash involving palms or soles
- Unexplained rash after a possible STI exposure
- Swollen groin lymph nodes
- A partner diagnosed with syphilis
- A possible STI exposure
- A positive syphilis test
- Concerns about STI exposure during pregnancy
A Gynecologist can assess female reproductive and genital health, while a Venerologist specializes in sexually transmitted and related skin/genital conditions.
Syphilis in Women: Don’t Wait for Symptoms
Syphilis can be silent.
A sore may heal.
A rash may disappear.
A woman may feel completely healthy while the infection remains.
That’s why the safest approach after a meaningful exposure or concerning symptom is:
Exposure or symptoms → Medical evaluation → Appropriate testing → Diagnosis → Treatment → Follow-up
Early detection can help prevent transmission and serious complications.

Frequently Asked Questions About Syphilis in Women
What is the first symptom of syphilis in women?
The classic first-stage symptom is a painless, usually firm, round sore (chancre) at the site where the infection entered the body. In women, it can occur in locations that are difficult to see, such as inside the vagina or on the cervix.
Can syphilis occur without symptoms?
Yes. Many infections are asymptomatic or unrecognized, and latent syphilis has no clinical signs.
Does a syphilis sore hurt?
The classic chancre is usually painless. However, not every genital ulcer is syphilis, so professional evaluation and testing are important.
Can a syphilis sore disappear on its own?
Yes. The chancre can heal without treatment, but this does not mean the infection has been cured.
What blood tests are used for syphilis?
Testing may include RPR, VDRL, TPHA/TPPA, and other treponemal tests, depending on the diagnostic approach.
Can syphilis be cured?
Yes. Syphilis is treatable and curable with appropriate antibiotic therapy.
Can syphilis affect pregnancy?
Yes. Untreated syphilis can be transmitted to the fetus and cause congenital syphilis and serious pregnancy outcomes.
When should pregnant women get tested?
WHO recommends testing all pregnant women at least once and as early as possible, ideally at the first antenatal visit.
Can syphilis be treated during pregnancy?
Yes. Benzathine penicillin G is the recommended treatment for pregnant women with syphilis and is the treatment used to prevent transmission to the fetus.
Can you get syphilis again after treatment?
Yes. Treatment cures the infection but does not provide immunity against a future exposure.
