本圖表概述未經治療梅毒的疾病發展過程：1.一期梅毒：通常在感染的部位僅有一個潰口或潰瘍。2.二期梅毒：皮疹、毛髮脫落和流感樣症狀出現。3.潛伏期：可延續1-30年；無外在症狀。4.晚期梅毒：嚴重地損害心臟、腦和其他內部器官。最終可導致死亡。但是，多半的感染者決不會進入梅毒的此期病程。 This chart summarizes the development of untreated syphilis: 1. Primary stage: There is usually only one sore or ulcer at the point of infection. 2. Secondary stage: A skin rash, a loss of hair, and flu-like symptoms usually appear. 3. Latent phase: It can last from one to 30 years; there are no outward symptoms. 4. Late stage: Syphilis may manifest very serious damage to the heart, the brain, and other internal organs. This may even lead to death. However, more than half of the infected never enter this stage of syphilis.
