It is unclear whether SARS-CoV-2 can be shed into human milk and transmitted to a child via breastfeeding. To date, in the literature, the presence of SARS-CoV-2 RNA has only been detected in the breast milk of two mothers with SARS-CoV-2. In two cases, environmental contamination or retrograde flow from an infected infant could not be ruled out.
