Read the Comment.

Infectious disease transmitted sexually or congenitally through the placenta.
There is no evidence that the spirochete Treponema pallidum, which causes syphilis, is transmitted through breastmilk (Lawrence 2016 p463, Lanari 2012).

Avoid contact with skin lesions of secondary syphilis and stop breastfeeding if the lesions are in the chest area until they heal (Lawrence 2016 p463, OWH 2015, Lanari 2012). Normally, 24 hours after starting treatment with penicillin, no spirochetes are found in the lesions.
Monitor the infant and administer treatment if necessary.

In the case of congenital syphilis, mother and newborn should be treated with penicillin. Breastfeeding is not contraindicated.

The treatment of syphilis, penicillin or, in the case of allergy to penicillin, tetracycline or doxycycline, is compatible with breastfeeding.
