Evaluación del SARS-CoV-2 en la leche materna de 18 mujeres infectadas

Concern has been raised that severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2) may be transmitted to infants by
breastfeeding. A number of organizations advise that women infected with
SARS-CoV-2 may choose to breastfeed with protections to prevent
transmission of the virus through respiratory droplets. Of 24 case
reports on breast milk samples from women infected with SARS-CoV-2,
viral RNA was detected in 10 samples from 4 women.¹^-6
In some cases, environmental contamination or retrograde flow from an
infected infant could not be ruled out. Detection of viral RNA by
reverse transcriptase–polymerase chain reaction (RT-PCR) does not equate
with infectivity. To date, SARS-CoV-2 has not been isolated from breast
milk, and there are no documented cases of transmission of infectious
virus to the infant through breast milk. However, potential for viral
transmission through breast milk remains a critical question for women
infected with SARS-CoV-2 who wish to breastfeed.
