10 Common STDs You Should Know About

5. Syphilis

Syphilis is a bacterial infection spread by contact with syphilitic sores known as chancres. The sores can be painless and can occur on the genitals or in the mouth. Historically, syphilis was associated with serious or even life-threatening complications causing damage to the brain, heart, and other organs. Fortunately, the infection is now curable, especially in the early stage. One course of antibiotics is typically enough to stop the infection, but more progressed cases can require additional courses. The main symptom of syphilis is sores where the bacteria entered the body. Many people develop a single sore, though some have several. As the infection progresses, it may lead to a rash and discharge. Condom use can reduce the risk of a syphilis infection, but it's still possible to transmit the bacteria through contact with an exposed sore.
