Key points include:

  • Robust evidence indicated that SARS-CoV-2 does NOT transmit through human milk
  • Infected mothers can pass antibodies in their milk that help protect their babies against SARS-CoV-2
  • Under appropriate hand hygiene and masking efforts,
    • ALL evidence reveals that the risk to babies from their infected mothers is virtually nil
  • NO evidence that babies should be separated from their infected mothers who are able to establish or continue breastfeeding
  • The dominant transmission route for SARS-CoV-2 is through inhalation of respiratory droplets containing the virus particles
  • Other potential transmission routes are fecal-oral, trans-placental and through a contaminated surface (much lesser extent)
