Study From United States Suggests COVID-19 Cannot Be Transmitted Through Breast Milk
Highlights
  • The COVID-19 study examined 64 samples of breast milk
  • Samples were collected from 18 women across the United States
  • All 18 women were infected with Novel Coronavirus (SARS-CoV-2)

California: Answering the critical question of whether COVID-19 can be transmitted through breast milk or not, a recent study suggests that breast milk cannot transmit the virus to the infant. The study, which was published in the online edition of JAMA was conducted by the researchers from the University of California San Diego School of Medicine and University of California Los Angeles. The study examined 64 samples of breast milk collected by the Mommy’s Milk Human Milk Research Biorepository from 18 women across the United States infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Although one sample tested positive for viral RNA (Ribonucleic acid), subsequent tests found that the virus was unable to replicate, and thus unable to cause infection in the breastfed infant.

“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, PhD, MPH, co-principal investigator of the study, professor of paediatrics at UC San Diego School of Medicine, director of Mommy’s Milk Human Milk Research Biorepository and co-director of the UC San Diego Center for Better Beginnings.

Our findings suggest breast milk itself is not likely a source of infection for the infant, Christina Chambers added.

The current recommendations to prevent transmission while breastfeeding are hand hygiene and sterilising pumping equipment after each use.

“In the absence of data, some women infected with SARS-CoV-2 have chosen to just not breastfeed at all,” said Grace Aldrovandi, MD, co-principal investigator of the study, chief of the Division of Infectious Diseases at UCLA Mattel Children’s Hospital and a professor of paediatrics in the David Geffen School of Medicine at UC Los Angeles.

We hope our results and future studies will give women the reassurance needed for them to breastfeed. Human milk provides invaluable benefits to mom and baby, added Grace Aldrovandi.

Early breastfeeding is associated with a reduced risk of sudden infant death syndrome and obesity in children, as well as improved immune health and performance on intelligence tests. In mothers, breastfeeding has been associated with lower risks for breast and ovarian cancer, cardiovascular disease and type 2 diabetes.

The researchers also mimicked conditions of the Holder pasteurization process commonly used in human donor milk banks by adding SARS-CoV-2 to breast milk samples from two different donors who were not infected.

The samples were heated to 62.5-degree celsius for 30 minutes and then cooled to 4-degree celsius. Following pasteurization, infectious virus was not detected in either sample.

This is a very positive finding for donor milk, which so many infants, especially those born premature, rely on. Our findings fill in some important gaps, but more studies are needed with larger sample sizes to confirm these findings, said Christina Chambers.

Christina Chambers said future work will not only look at whether breast milk is free of the virus, but also whether it contains active antiviral components. For example, antibodies to SARS-CoV-2 that women may produce after exposure to the virus and then transfer to their infants through breast milk, protecting them from COVID-19.

NDTV – Dettol Banega Swasth India campaign is an extension of the five-year-old Banega Swachh India initiative helmed by Campaign Ambassador Amitabh Bachchan. It aims to spread awareness about critical health issues facing the country. In wake of the current COVID-19 pandemic, the need for WASH (WaterSanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign highlights the importance of nutrition and healthcare for women and children to prevent maternal and child mortality, fight malnutrition, stunting, wasting, anaemia and disease prevention through vaccines. Importance of programmes like Public Distribution System (PDS), Mid-day Meal Scheme, POSHAN Abhiyan and the role of Aganwadis and ASHA workers are also covered. Only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and become a Swasth or healthy India. The campaign will continue to cover issues like air pollutionwaste managementplastic banmanual scavenging and sanitation workers and menstrual hygiene
