How long can syphilis be treated?

Syphilis is a systemic sexually transmitted disease caused by Treponema pallidum infection. It is normal to use long-acting penicillin for syphilis treatment. The treatment course is normally 3 to 4 weeks. However, at the end of the treatment course, the patient does not recover immediately and is not infectious. Instead, the syphilis RPR titer should be checked regularly every three months. only when the titer turns negative is it considered that the treponema is completely eliminated and not infectious. Until then, it is recommended that sexual intercourse should be prevented. However, if it is difficult to turn negative for a long time, you can also take protective measures, such as the use of condoms in the same room. However, this is not 100% guaranteed that infection will not occur.
