What is latent syphilis? Do I need treatment? Latent syphilis is also known as latent syphilis. If the patient has not been treated, or if the treatment is inappropriate or insufficient, or if the treatment is incomplete, the patient may still be positive for syphilis seropositivity even though the syphilis symptoms have disappeared; or if the patient has never had any symptoms after infection, but is found to be positive for syphilis seropositivity during a blood test, the patient is a latent syphilis patient. Most of the syphilis patients fall into this category. Although these patients are asymptomatic and healthy in appearance, syphilis spirochetes are still present in their bodies and can produce symptoms at any time when resistance is reduced, and they are also contagious, especially early latent syphilis. Therefore, once latent syphilis is detected, it must be treated immediately to kill the syphilis spirochetes hidden in the body as soon as possible, thus eliminating the hidden danger. What are the consequences of untreated latent syphilis? Untreated latent syphilis will have the following outcomes: 1. Clinical symptoms appear after a certain period of time. Early latent syphilis often occurs with recurrent phase II syphilis damage, which is infectious. Late latent syphilis is associated with third-stage syphilis symptoms, especially cardiovascular and central nervous system symptoms; 2. congenital syphilis children, especially early latent syphilis. Therefore, the seropositivity of syphilis should be checked regularly before and during pregnancy, and if found to be positive, pregnancy should be avoided, treated immediately or terminated; 3. The seropositivity remains positive for a long time without symptoms and remains latent for life; 4. After several decades, the seropositivity turns negative naturally and there are no symptoms, and natural recovery is achieved. The latter two endings are not serious but not rare. Therefore, latent syphilis should be treated actively.
