What are STIs?

STI stands for sexually transmitted infections. Sometimes these are called STDs or sexually transmitted diseases.

You can get an STI through sex (oral, anal, or vaginal) with someone who has an untreated STI. Using prevention methods can reduce your vulnerability to STIs and there are many different prevention options to keep you and your partner(s) safe. These include physical barriers like condoms, medication such as DoxyPEP, and behavioral changes like abstaining from sex, entering in a mutually monogamous relationship after both being tested and treated for all STIs, or reducing the number of partners or frequency of sex without barriers.

STIs are very common and are nothing to be ashamed about. All STIs are treatable and most are curable! 

If you are sexually active, getting tested is the first step in protecting your sexual health.

Syphilis Fast Facts

What is syphilis?

Syphilis is a sexually transmitted infection (STI), meaning you can get it by having sex (oral, anal, or vaginal) with someone who has untreated syphilis

Syphilis can affect anyone who has unprotected sex, regardless of gender or sexual orientation.

The only way to know for sure if you have syphilis is to get a simple blood test.

If you are sexually active, you should be tested for syphilis.

Health departments can confidentially test you and your partner(s) any time for syphilis, at little or no cost!

There are four stages: primary, secondary, latent, and tertiary and each stage has different signs and symptoms. Symptoms can change as time goes on, and some people may not notice any symptoms at all. So, that is why it is best to regularly get tested for STIs, including syphilis, if you have unprotected sex.

Some common signs and symptoms of syphilis include:

  • Small sores on your genitals, bottom, or mouth,
  • Rash on your chest, back, palms, or feet
  • Flu-like symptoms
  • And more

Yes! Syphilis is treatable and curable with antibiotics.

Getting treatment right away can prevent irreversible damage to your heart and brain including deafness, blindness, and other serious health problems. Since it is possible to get re-exposed and get syphilis again, it is important that all your partners are tested and treated as well.

Your local health department can help notify your partner(s) anonymously so they can get tested and treated.

  • Using condoms the right way when you have sex
