Syphilis

Syphilis is a bacterial infection that's usually caught by having sex with someone who's infected.

It's important to get tested and treated as soon as possible if you think you might have syphilis, as it can cause serious problems such as damage to your heart, brain and nervous system if it's left untreated.

You can catch syphilis more than once, even if you've been treated for it before.
Get tested if you are worried you might have it, have symptoms or if a sexual partner has been diagnosed with syphilis.
