STDs That Show on Your Face - Men's Health - FOXNews.com

"Syphilis is caused by infection of the Treponema pallidum bacterium and is spread by direct sexual contact (including oral) with an individual with infectious syphilis lesions (called chancres). These chancres usually appear about three to six weeks after sex at the site of sexual contact, usually the genitals, during what is called primary syphilis. Secondary syphilis symptoms appear about 4 to 10 weeks after the appearance of primary lesions if the infection is left untreated and tertiary symptoms may appear after that. Treatment can be successfully achieved using antibiotics."
