PRE-PRINT: Reassuring news about the safety of breastfeeding amidst the COVID-19 pandemic.
To doubly reassure mothers who want to breastfeed in these worrying times of a global pandemic, a new follow-up paper (IN PRE-PRINT) by Krogstad P et al. confirms that there is no evidence of infectious SARS-CoV-2 in human breast milk.
A paper was originally published in August 2020 with the first results of the study – that found no evidence of the replication-competent (active) virus in breast milk.
Now, 13 months later, as the Covid-19 global pandemic continues to spread around the world, Krogstad and colleagues, including Professor Lars Bode (featured in our microbiome academy), have released another paper - currently in preprint, so awaiting to be peer-reviewed.
This study includes a larger cohort of 110 breastfeeding women.
Breast milk samples from 110 women were collected.
- 65 of the women were confirmed with a SARS-CoV-2 diagnostic test.
- 36 had symptoms but without tests.
- 9 had symptoms but a negative SARS-CoV-2 diagnostic test.
In the study group of 110 women, SARS-CoV-2 RNA was detected in the milk from 6 of the 65 women (9.2%) with recent confirmed infection.
"Neither infectious virus nor subgenomic RNA (a marker of virus infectivity) were detected in any of the samples."
The second paper confirms the same result as the first paper.
There is no evidence of infectious SARS CoV-2 in breast milk, even if the mother tests positive for the coronavirus.
“We found no evidence that infectious SARS-CoV-2 is present milk from recently infected women, even if SARS-CoV-2 PCR tests are positive, providing reassurance of the safety of breastfeeding.”
The research team for this paper includes Professor Lars Bode. Professor Lars Bode is one of the 7 scientists featured in our Breast Milk and the Infant Microbiome course.
