Syphilis is a well known STI, which if left untreated can lead to potentially life-threatening problems. These include heart failure and seizures, among other medical issues. The NHS advises going to a sexual health clinic or seeing a GP if you or a partner show any symptoms of the infection.
Small sores (ulcers) on your penis, vagina, or around your bottom (anus) – these are usually painless and you may only have one of them.
Sores in other areas, including in your mouth or on your lips, hands or bottom.
White or grey warty growths – most commonly on your penis, vagina or around your anus.
A rash on the palms of your hands and soles of your feet that can sometimes spread all over your body – this is not usually itchy.
“Some of these problems may not appear for many years after being infected with syphilis,” the NHS adds.
The most common way of getting syphilis is by having unprotected sex with someone who’s infected.
Therefore, the use of condoms is recommended to prevent getting infected.
