Mothers Are Unlikely to Transmit Coronavirus to Infants Through Breast Milk

A new study reported good news regarding mothers infected with the SARS-CoV-2 coronavirus. According to a study published by the JAMA on August 19, 2020, the SARS-CoV-2 has not been isolated from breast milk, and there are no documented cases of transmission of infectious virus to the infant through breast milk.

“Detection of viral RNA does not equate to infection. It has to grow and multiply in order to be infectious and we did not find that in any of our samples,” said Christina Chambers, Ph.D., MPH, co-principal investigator of the study, professor of pediatrics at UC San Diego School of Medicine, in a press statement. “Our findings suggest breast milk itself is not likely a source of infection for the infant.”

This research indicates the potential for viral transmission through breast milk remains a critical question for women infected with SARS-CoV-2 who wish to breastfeed.

On May 5, 2020, the U.S. CDC said 'We do not know whether mothers with COVID-19 can transmit the virus via breast milk, but the limited data available suggest this is not likely. Whether and how to start or continue breastfeeding should be determined by the mother in coordination with her family and healthcare providers.'
