COVID-19: Breastfeeding and human milk banking

12 March 2020

Please note: This information is accurate as of today but new information about COVID-19 transmission is emerging daily. Please consult resources such as the CDC and the WHO for the most recent guidance.


Breast milk is the optimum source of nutrition for babies, yet the emergence of COVID-19, caused by the novel coronavirus SARS has raised questions both about the safety of breastfeeding and human milk banking.

Although there is much unknown about COVID-19, the recommendations below, sourced from the Center for Disease Control and Preventions (CDC) in the USA,  The World Health Organisation, UNICEF, the Human Milk Banking Association of North America (HMBANA), the European Milk Bank Association and the Academy of Breastfeeding Medicine (AMB) all agree breastfeeding should be continued.

According to the CDC, to date the virus has not been isolated in the breastmilk of infected women. Neither is there evidence at this stage, that the virus can be transmitted through breastmilk. Although the virus was not found in the breastmilk of infected women, antibodies against SARS-CoV were detected in one sample. (Center for Disease Control and Prevention [CDC], 2020)

Given low rates of transmission of respiratory viruses through breast milk, the World Health Organization states that mothers with COVID-19 can breastfeed. UNICEF too are encouraging mothers infected with COVID-19 to continue breastfeeding while taking precautions which include wearing a mask when feeding or near the baby, frequent hand washing before and after handling the baby and disinfecting all surfaces. These practice careful  practices should continue for at least 5-7 days until cough and respiratory secretions are dramatically improved.Should the mother be too ill to breastfeed, expressed breastmilk can be fed to the baby. (UNICEF,2020).

No evidence of the virus was found in breastmilk, cord blood, amniotic fluid or throat swabs of newborns whose mothers had tested positive for the virus (Chen et al., 2020).

Editor-in-Chief of Breastfeeding MedicineArthur Eidelmanstates: “Given the reality that mothers infected with coronavirus have probably already colonized their nursing infant, continued breastfeeding has the potential of transmitting protective maternal antibodies to the infant via the breast milk. Thus, breastfeeding should be continued with the mother carefully practicing handwashing and wearing a mask while nursing, to minimize additional viral exposure to the infant” (Liebert, 2020).



The choice to breastfeed is the mother’s and families.

If the mother is well and has only been exposed or is a PUI with mild symptoms, breastfeeding is a very reasonable choice and diminishing the risk of exposing the infant to maternal respiratory secretions with use of a mask, gown and careful handwashing is relatively easy.

If the mother has COVD-19, there may be more worry, but it is still reasonable to choose to breastfeed and provide expressed milk for her infant. Limiting the infant’s exposure via respiratory secretions may require more careful adherence to the recommendations depending on the mother’s illness.

There are several choices in the hospital concerning housing for a breastfeeding mother and her infant.

  1. Rooming-in (mother and baby stay in the same room without any other patients in that room) with the infant kept in a bassinet 6 feet from the mother’s bed and taking precautions to avoid spreading the virus to her infant, including washing her hands before touching the infant and wearing a face mask, for direct contact with the infant and while feeding at the breast. Ideally, there should be another well adult who cares for the infant in the room.
  2. Temporary separation – primarily because the mother is sick with the COVID-19 infection and needs medical care for herself in the hospital. Mothers who intend to breastfeed / continue breastfeeding should be encouraged to express their breast milk to establish and maintain milk supply. If possible, a dedicated breast pump should be provided. Prior to expressing breast milk, mothers should practice hand hygiene. After each pumping session, all parts that come into contact with breast milk should be thoroughly washed and the entire pump should be appropriately disinfected per the manufacturer’s instructions. This expressed breast milk should be fed to the newborn by a healthy caregiver.

Mothers and families may need additional guidance and support to continue breastfeeding, to utilize expressed breast milk, to maintain her milk production and to store milk for later use while the mother is sick with COVID-19.

Human Milk Banking

Human Milk Banks have numerous safety measures in place which ensure that every bottle of donor milk is safe. These included careful screening of potential donors as well as proven pasteurisation methods, which kill viruses and bacteria and microbiology testing of the milk.

Despite the fact that COVID-19 is a new virus and there is limited data about it, the similarities with SARS and MERS are pertinent and can be applied to milk banking namely, that these viruses are inactivated by Holder pasteurisation (62.5° C for 30 minutes.

Notwithstanding this HMBASA proposes additional screening questions be added to the current lifestyle/health questionnaire:

  • Have you travelled through or stayed in a high-risk area during the past 14 days?
  • Have you been in close contact with any confirmed or suspected case of Covid-19?
  • Have you attended a facility where a positive case of Covid-19 has been confirmed?

If any responses are positive, these donors should be suspended for 14 days. Should any donor mothers become ill with signs of a respiratory infection the milk banks should be notified immediately (EMBA,2020).
