COVID-19 cannot be transmitted through breast milk, suggests Study


California: Answering the vital query of whether or not COVID-19 can be transmitted through breast milk or not, a current examine suggests that breast milk cannot transmit the virus to the toddler. The examine, which was revealed within the on-line version of JAMA was carried out by the researchers from the University of California San Diego School of Medicine and the University of California Los Angeles.

The examine examined 64 samples of breast milk collected by the Mommy`s Milk Human Milk Research Biorepository from 18 ladies throughout the United States contaminated with extreme acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Although one pattern examined optimistic for viral RNA, subsequent exams discovered that the virus was unable to copy, and thus unable to trigger an infection within the breastfed toddler.

“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,” mentioned Christina Chambers, PhD, MPH, co-principal investigator of the examine, 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,” Chambers added. The present suggestions to stop transmission whereas breastfeeding is hand hygiene and sterilising pumping gear after every use.

“In the absence of data, some women infected with SARS-CoV-2 have chosen to just not breastfeed at all,” mentioned Grace Aldrovandi, MD, co-principal investigator of the examine, chief of the Division of Infectious Diseases at UCLA Mattel Children`s Hospital and a professor of paediatrics within 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 Aldrovandi. 

Early breastfeeding is related to a diminished threat of sudden toddler dying syndrome and weight problems in kids, in addition to improved immune well being and efficiency on intelligence exams. 

In moms, breastfeeding has been related to decrease dangers for breast and ovarian most cancers, heart problems, and kind 2 diabetes.

The researchers additionally mimicked situations of the Holder pasteurization course of generally utilized in human donor milk banks by including SARS-CoV-2 to breast milk samples from two completely different donors who weren’t contaminated.

The samples have been heated to 62.5-degree celsius for 30 minutes after which cooled to 4-degree celsius. Following pasteurization, the infectious virus was not detected in both pattern.

“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,” mentioned Chambers.

Chambers mentioned future work won’t solely have a look at whether or not breast milk is freed from the virus, but additionally whether or not it comprises lively antiviral elements. For instance, antibodies to SARS-CoV-2 that ladies could produce after publicity to the virus after which switch to their infants through breast milk, defending them from COVID-19.
