Breastfeeding through viral respiratory infections

Baby breastfeeding

There’s a lot of discussion and understandable concern about Coronavirus right now and it’s natural to wonder how best to care for a little one at a time like this. Breastfeeding and providing breastmilk to your baby is still one of the best things you can do for your baby’s health and development.

We know your highest priority as a parent is keeping your loved ones safe and as healthy as possible. It’s important for you to stay healthy, too.  Influenza (the “flu”) remains the most common viral respiratory infection transmitted in the United States. At this time, however, the newer threat of the Coronavirus (COVID-19) is spreading around the world.

The same precautions we take with trying to avoid other viral illnesses should be used now for everyone: 

  • Wash your hands. Wash them frequently, with warm water and soap for at least 20 seconds. If it is not possible to wash your hands with soap and water, use a hand sanitizing solution with at least 60% alcohol.
  • During flu “seasons” and other high-risk times, minimize visitors to your home and avoid outings that involve large crowds, especially indoor events. It is possible for an infected person to transmit the virus even if they aren’t showing symptoms such as a fever.
  • Clean and disinfect surfaces and objects frequently touched in the home and car.
  • Cough or sneeze into a tissue, throw the tissue away in the trash, and make sure to wash your hands after this is done.

Your breastmilk helps to form your baby’s immune system and provide protection from illness. This is due to components like immunoglobulins and antibodies – they are anti-infective properties found in breastmilk.

Research on viral illnesses like COVID-19 is limited, so guidance is based on previous experience with viral respiratory illnesses like influenza. Because it is so new, we don’t yet know whether the COVID-19 virus is transmitted via breastmilk. The more common and likely form of transmission is person to person. The virus is transmitted in respiratory droplets when an infected person coughs or sneezes – this is the same way the flu is passed from person to person.  


What does this mean for breastfeeding moms?

Keep directly breastfeeding, as much as you are able.

    •  If you do become infected, or suspect/know you may have been exposed to someone who is infected:
      • Wear a mask when holding your baby and while feeding them
      • Wash your hands before the feeding starts, and again directly after
      • Wash your hands before and after you touch your baby at other times, such as before and after diaper changes.
      • Let others help you, especially if they are well or healthier. It’s really hard to get rest as a new mom, but rest is critical to overcoming an infection.
      • Stay hydrated. This is important for moms at all times and becomes even more important when you’re breastfeeding and fighting an infection or fever. The fever will dehydrate you so it is important to replace those fluids.

If, or when, you are pumping:

    • Wash your hands before assembling your pump parts, and wash them again immediately after you’ve finished your pumping session.
    • After pumping, wash the parts with warm, soapy water, rinse, and air dry
    • Wipe down the pump itself with an all-purpose cleaner or wipe, without getting the pump too wet.  Allow to air dry
    • If possible, let someone healthy (or at least, healthier) feed the baby with a bottle
    • Stay hydrated.

What about medications that might be used to treat COVID-19, or even Influenza-A?

As of the writing of this article, there is no exact known medication or vaccine to treat COVID-19. There are various medications used for other viral respiratory infections that are being tried and considered. Discuss the fact that you’re breastfeeding with your provider and express your desire to continue breastfeeding.

If your doctor recommends taking antiviral medication, please ensure they are aware of your breastfeeding and pumping routine. Ask them whether there are risks to your baby. This will allow you to make the best decision possible while trying to minimize risk of transmission to your baby and trying to maintain your milk supply.
