  "abstract": "Pregnant women with late latent or latent of unknown duration syphilis are recommended to receive three doses of benzathine penicillin G each 9 or fewer days apart; data on interval variations are limited. We found no significant difference in risk of congenital syphilis between 9-day and 6-8 day dosing intervals.\n\nSummaryAmong pregnant women with late latent or latent of unknown duration syphilis, there was no difference in risk of congenital syphilis between 9-day and 6-8 day maternal treatment dosing intervals.",
