When syphilis infection is suspected, it is usually ruled out after a 3-month follow-up and a negative test for syphilis spirochetes.
Testing is generally done at the immediate, 6-week, and 3rd month, respectively. Immediate testing is to rule out that the exposed person is infected with syphilis, and the 6th week is the general window of infection for early detection of syphilis infection. The longest incubation period for syphilis is 90 days, after which a negative result can be ruled out. Therefore, a negative syphilis antibody at 5 weeks does not exclude infection.
Syphilis can be cured with early, adequate and regular treatment. Once found infected with syphilis, go to the hospital for treatment as soon as possible to avoid delay.
