Congenital syphilis following negative antenatal screening

We report a case of severe early congenital syphilis in the infant of a mother who acquired syphilis in mid pregnancy. The mother had received full antenatal care including serological screening for syphilis. Congenital syphilis is re-emerging in a number of industrialised countries and this report demonstrates that some of the most serious cases cannot be prevented by routine antenatal screening.
