How it spreads
Syphilis is spread through skin-to-skin contact with an infected area or oral, vaginal or anal sex without a condom.
Symptoms
Symptoms are not always noticed and a blood test is usually required to identify infected individuals. A single, painless, clear ulcer may appear on the genitals. After a few weeks, glands in the groin will enlarge; a rash on the body and flu-like symptoms usually follow several weeks later.
Complications
If left untreated, a person may develop cardiovascular syphilis after 10-30 years. This can result in aneurysm formation.
How to avoid it
Condoms reduce the risk, but only protect the skin that is covered.
Treatment
Antibiotic injections.
