Common STIs - Syphilis

Home: Survivors: For Sex Workers: Sexually transmissible infection

Cause

Syphilis is caused by a bacterium called Treponema Pallidum. Syphilis is uncommon in the southern parts of Australia today but is still widespread in many parts of the world.

Symptoms

People often have no symptoms. Syphilis usually has three stages:

• Primary Syphilis: 0 - 3 weeks. A painless sore usually on the genital area.
• Secondary Syphilis: 0 - 2 months. Symptoms include swollen glands and a rash (especially on the soles of the feet and palms of the hands).
• Tertiary Syphilis: may occur many years later. Untreated syphilis may have no symptoms for many years but may eventually cause problems in the brain, heart or skin.

How is it transmitted?

By having unprotected sex with someone who has syphilis.

Management

Penicillin injections are given in the early phases. Untreated syphilis may cause serious illness after many years of infection. Complex medical treatments may then be required.

Prevention

Condoms for all vaginal, anal and oral sex.
