Emerg Microbes Infect. 2020 Dec;9(1):1467-1469. doi: 10.1080/22221751.2020.1780952.

Abstract

A maternal woman was positive for SARS-CoV-2 tested in throat swabs but negative tested in other body fluids, and she had IgG and IgA detected in breast milk. Her infant negative for SARS-CoV-2 at birth had elevated IgG in serum but quickly decayed. These findings suggest that breastfeeding might have the potential benefit to the neonates.

Keywords: COVID-19; IgA; IgG; breastmilk; maternal woman.
