Symptoms and stages
Syphilis is called “the great imitator” because so many signs and symptoms are similar to other diseases. A person can have syphilis and not know it.
Symptoms of syphilis in adults can be divided into stages:
- Symptoms begin 1-12 weeks after exposure:
- A painless, open sore(s) on the mouth, genitals or anus
- Sore(s) can be “hidden” in the vagina or rectum
- Sore(s) last 1-5 weeks
- Sore(s) goes away, but syphilis is still in the blood
- Symptoms show up 6 weeks to 6 months after sore appears:
- A rash anywhere on the body
- Flu-like symptoms
- Whitish-grey patches on mouth/lips, wart-like lesions around genitals, and/or hair loss can occur but are less common
Latent and late stages
- No sores or rashes, but syphilis is still in the blood and can affect the heart, brain and other organs over time (tertiary syphilis)
Who is at highest risk?
Syphilis occurs worldwide, most commonly in urban areas.
The number of cases is rising fastest in:
- Men who have sex with men
- Young adults ages 15 to 25
- People who exchange sex for drugs or money
- Native Americans and African Americans
Your risk of syphilis increases if you:
- Have unprotected sex (do not use condoms or do not use them correctly).
- Have multiple sex partners.
- Have a sex partner who has syphilis.
- Have sex with a partner who has multiple sex partners.

- Syphilis can be cured if it is diagnosed early and treated with prescription medication.
- However, while treatment will prevent further damage, it will not repair damage already caused by late stage syphilis.
- Untreated syphilis can be fatal.
- Syphilis greatly increases the chance of either getting or spreading HIV.
- People who are HIV+ may develop neurosyphilis faster than those who are negative.
- In addition, untreated syphilis during pregnancy may spread to the developing baby. This is called congenital syphilis.
- Syphilis is passed from person to person through direct contact with a syphilis sore.
- Transmission occurs during vaginal, anal, or oral sex.
- Pregnant women with the disease can pass it to the babies they are carrying.
- Syphilis cannot be spread through contact with toilet seats, swimming pools, hot tubs, bath tubs, shared clothing, or eating utensils.
Any sexually active person can get syphilis through unprotected vaginal, anal, or oral sex.
- The surest way to avoid syphilis is to abstain from sexual intercourse or be in a long-term mutually monogamous relationship with a partner who has been tested and is known to be uninfected.
- Latex condoms, when used consistently and correctly, can reduce the risk of syphilis only when the infected areas are covered or protected by the condom.
- Always use latex condoms during vaginal and anal sex.
- Use a latex condom for oral sex on a penis.
- Use a latex barrier (dental dam or condom cut in half) for oral sex on a vagina or anus.
Get tested regularly.
- You can get a test from a health care provider, or your family doctor.
