The Zika virus has been affecting a large part of the Brazilian population since 2014, and its pathology has raised questions on the transmission route, symptoms ,prevention, and treatment, as well as on neurological changes, which were previously not associated with the disease. To clear doubts on the transmission of the virus during breastfeeding, this study aimed to review and analyze studies, published from January 2014 to April 2017, regarding the relationship between breastfeeding and Zika virus exposure and focusing on the importance of breastfeeding. A search was performed in main databases, resulting in 85 articles, of which 38 were selected based on search criteria. All articles reported on the presence of Zika virus RNA in human milk. Among them, 34.21% had no stance on breastfeeding, 28.94% supported it, 18.42% did not recommend it, while 18.42% explained the need for further studies on the subject. The World Health Organization recommends breastfeeding for all mothers infected with Zika virus because the benefits of breastfeeding outweigh the risks of disease transmission, and there is no scientifically proven case of transmission through this route.
