Syphilis in pregnancy, congenital syphilis, and factors associated with mother-to-child transmission in Itapeva, São Paulo, 2010 to 2014

This study describes cases of syphilis in pregnancy (SiP) and congenital syphilis (CS) and identifies factors associated with mother-to-child transmission in patients in Itapeva from January 1, 2010 to December 31, 2014. Using SiP and CS notification forms and medical records, a cross-sectional study involving 149 pregnant women was conducted. Annual SiP detection rates ranged from 16.3-31.4/1000 live births. Most women had prenatal care started at the first trimester of pregnancy with ≥6 visits. Mother-to-child transmission rate was 69.7%. CS incidence rates varied from 9.1-22.3/1000 live births. The results suggest low quality of prenatal care.
