Condoms provide protection but only if they cover the infected area.
To test for Syphilis, a swab is taken from the initial sore or a blood test.
Syphilis is effectively treated with penicillin. Sex should be avoided after treatment until any rashes or sores have gone.
If you have been diagnosed with syphilis it is important to let all your sexual partners know so that they can be tested and treated if needed. Your doctor can assist with this. You can check out www.letthemknow.org.au for advice and assistance with this.
