Abstract

Purpose of reviewOne important question from the outset of the pandemic has been whether a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected person's milk might be a vehicle for SARS-CoV-2 transmission. This review summarizes the most recent data on this topic.Recent findingsA SARS-CoV-2 sIgA response in milk after infection is very common. To date, there has been no evidence that SARS-CoV-2 transmits via human milk. Though viral RNA has been identified in a minority of milk samples studied, infectious virus particles have not.SummaryThe highly dominant transmission route for SARS-CoV-2 is via inhalation of respiratory droplets containing virus particles. Other routes of transmission are possible, including fecal-oral, trans-placental, and to a much lesser extent, via a contaminated surface. SARS-CoV-2 cannot transmit via human milk. There is no evidence that infants should be separated from SARS-CoV-2-infected mothers who are well enough to establish or continue breastfeeding.
