Syphilis can usually be completely ruled out 90 days after high-risk behavior. The incubation period for syphilis is about 10 to 90 days.
If you are infected with syphilis after a high-risk behavior, you can usually test positive for syphilis antibodies. Due to individual differences, the time for the antibodies to appear varies, and the incubation period for the syphilis spirochete virus is usually about 10 to 90 days. If the test is negative after 90 days of high risk, syphilis can usually be completely excluded.
Syphilis is a sexually transmitted disease caused by the infection of the syphilis spirochete, and the transmission channels are sexual, mother-to-child, and blood transmission. Early syphilis manifests itself in the form of chancre, and in the middle and late stages of syphilis, it mainly leads to skin, mucous membranes, and organ damage, which poses a threat to the life of the patient, and needs to be actively treated, usually with penicillin intramuscular injection therapy, and review and follow-up.
If you are worried about the occurrence of syphilis after high-risk behavior, it is recommended that you actively go to the hospital for examination and clear diagnosis, so as not to delay the condition.
