Syphilis can be transmitted even if the skin is not broken. Syphilis is a sexually transmitted disease caused by the syphilis spirochete, which is mainly transmitted through sexual contact, from mother to child, and through blood. Syphilis can also be transmitted through sexual intercourse when the skin is not broken. If you have unsafe sexual contact with a person suspected of having syphilis, or if you develop ulcers or rashes on your genitals, you should seek medical attention promptly to complete the relevant examinations. Syphilis can’t be cured by itself, it can be treated with penicillin, and the sexual partner of the syphilis patient should also be treated, and sexual intercourse should be strictly prohibited during the treatment period to avoid cross-infection.
