Syphilis is one of those STDs that can be cured completely if caught on time. But left untreated, the disease can progress to its later stages, at which point syphilis symptoms can become severe and even life-threatening. This is why it’s so essential to recognize early syphilis symptoms if you’re at risk for infection.

Early syphilis symptoms usually manifest in the form of a sore or multiple sores in the area where the infection initially entered the body (typically the genitals). Syphilis sores are usually small, firm, round, and painless. Early syphilis symptoms can last up to six weeks and often disappear without treatment. But just because those initial syphilis symptoms have cleared up does not mean that you’re no longer infected.

Anyone who has unprotected sex can benefit from a syphilis test, especially since early syphilis symptoms aren’t always easy to identify. But if you do start experiencing syphilis symptoms, STD testing is critical if you want to avoid long-term health-related consequences. Remember, if your STD test for syphilis does come back positive, you can begin treatment immediately. So the sooner you undergo syphilis testing, the sooner those syphilis symptoms can start to make their way out of your system.
