According to the Centers for Disease Control and Prevention (CDC), a case of congenital syphilis (CS) is defined as illness in an infant from whom lesional, placental, umbilical cord, or autopsy material specimens demonstrated T. pallidum by dark-field microscopy, fluorescent antibody, or other specific stain; an infant whose mother had untreated or inadequately treated syphilis at delivery (ie, any nonpenicillin therapy or penicillin administered <30 days before delivery); or an infant or child who has a reactive treponemal test for syphilis and any of the following: evidence of CS on physical examination, evidence of CS on radiographs of long bones, reactive cerebrospinal fluid (CSF) venereal disease research laboratory test (VDRL), elevated CSF cell count or protein (without other causes) or a reactive fluorescent treponemal antibody absorbed–19S-immunoglobulin M (IgM) antibody test or IgM enzyme-linked immunosorbent assay. This definition includes infants who are stillborn to women with untreated syphilis.
