Usually, sensible application of condoms essentially prevents infection with the syphilis spirochete. However, improper application, or contact through other means, may also lead to infection.
The source of syphilis infection is the patient himself, and syphilis spirochetes are present in the patient’s semen, skin lesions, blood and saliva. The use of condoms can effectively prevent transmission through semen and skin lesions, but if they are not worn all the way through, or if they are torn, there is a certain risk of infection.
In addition, the patient’s saliva also contains syphilis spirochetes. When kissing, if the partner has mouth ulcers or other diseases, syphilis spirochetes can enter the organism from the skin lesions and trigger infection.
It is recommended that patients should avoid sexual intercourse during the treatment period, and if they do have sex, they should take protective measures to avoid infection.
