Treatment to prevent congenital syphilis is considered adequate if it is initiated 30 days before delivery. This regimen prevents congenital syphilis.

Additionally, the pregnant woman must receive treatment based on the staging of the case:

Primary, secondary, and early latent syphilis:

■ 1 dose of benzathine penicillin (2,400,000 IU IM).

Syphilis of unknown duration, late latent, and tertiary syphilis:

■ 3 doses of benzathine penicillin (2,400,000 IU IM), with one-week intervals between doses.

Diagnostic tests for syphilis are classified into treponemal tests (TT) and non-treponemal tests (NTT).

NTT include the VDRL (Venereal Disease Research Laboratory), USR (VDRL modified for unheated serum), and RPR (Rapid Plasma Reagin, involving the addition of carbon particles and macroscopic reading). These tests measure antibodies produced in response to the infection.
