**New coronavirus and breastfeeding research**
Milk from breastfeeding mothers, who have recovered from COVID-19, *may contain antibodies to the novel coronavirus.* In a preliminary report, 15 human milk samples obtained from donors previously infected with SARS-CoV-2 and 10 negative control samples were tested for a variety of antibody activity. The data indicate that there is strong SARS-CoV-2 immune response in the majority of human milk samples collected after infection. Study leader, Rebecca Powell of The Icahn School of Medicine at Mount Sinai in New York, was quoted by Reuters, “Nursing mothers who are infected with the novel coronavirus should continue to breastfeed throughout their COVID-19 illness and beyond, because (other researchers) have shown transmission does not occur via milk, and we have determined that antibodies are almost certainly there, and may protect their babies from infection.” Her team’s report, posted on 5/8/20 on the preprint server medRxiv, has not yet been peer-reviewed or published in a medical journal.

SARS-CoV-2, commonly termed COVID-19 for the illness it causes, has infected >3.2 million people, including >220,000 deaths. Human milk IgG originates mainly from blood, therefore a SARS-CoV-2-reactive antibody (Ab) response in milk would be expected (1). However, IgG comprises only ~2% of milk Ab,....
