The authors report a case of Zika virus infected in a female living in Brazil who was infected during her 36th week of gestation. During testing they were able to detect Zika virus RNA in her breast milk. Culture of the virus demonstrated that it was viable and infective, with a clear cytopathic effect. The virus could still be detected by PCR 33 days following the onset of signs and symptoms and 9 days after she delivered her baby. No abnormalities were found during fetal assessment or after birth of the infant. The mother elected not to breast feed due to the persistence of the virus.
