How long can syphilis incubation period be detected?

Syphilis is a sexually transmitted disease caused by Treponema pallidum infection. The main detection method for syphilis is serological detection, mainly for antibody detection of Treponema pallidum. However, due to the initial stage of infection, the amount of Treponema pallidum in the body is relatively small, so serology cannot detect it in time. about 30 days after infection, when Treponema pallidum produces sufficient antibody quantity in the body, it can be detected by clinical reagents. Therefore, when syphilis infection is suspected, it can be counted from the beginning of high-risk sexual contact and extended for about 30 days. Serological tests can be done in hospitals to rule out syphilis infection.
