Syphilis is a sexually transmitted disease caused by the bacteria Treponema palladium. The infection has three stages, each of which has different symptoms and complications. If left untreated, syphilis will progress through each stage and can result in damage to internal organs including the brain, eyes and heart. Syphilis during pregnancy can cause serious problems in a baby. Syphilis mimics the symptoms of other diseases, so it can often be misdiagnosed, which is why routine STD tests are the only way to know your status for sure. To prevent syphilis, use condoms and get tested routinely. Find out about KnoWyo’s convenient, low-cost testing here.
