Key Takeaways


  • COVID-19 in newborns is very rare.
  • Newborns who have COVID-19 generally recover well.
  • It is still important to follow COVID-19 public safety measures and wear a mask around your baby if you yourself have contracted the disease.

New research published in The Lancet Child and Adolescent Health  out of the UK reveals that COVID-19 in newborns is rare. For babies that do experience COVID-19, their symptoms are usually mild and they recover quickly.

Researchers also found that of all the newborns born in the study period, premature newborns and Black, Asian, and other Minority Ethnic groups (BAME) were more likely to experience a COVID-19 infection. The exact reason for this is not known. 

Overall, the risk of babies developing COVID-19 is considered so low, even among babies of COVID-19 positive mothers, that researchers recommend mothers and babies remain together after birth wherever possible. Separating mother and baby for the sole purpose of trying to reduce transmission of COVID-19 is not beneficial.

What the Study Shows

Researchers in London reviewed the data from cases of COVID-19 that occurred in March and April of 2020. They looked specifically at babies who were admitted to hospital within the first 28 days of life due to a diagnosis of SARS-CoV-2 (COVID-19).

Study co-author Dr Christopher Gale explains some results.  “SARS-CoV-2 infection is very rare in newborn babies: over the study period during the first UK pandemic peak in March and April about 120,000 babies were born in the UK and only 66 of these had SARS-CoV-2 infection in hospital. “

Of the 66 newborns that were confirmed to have COVID-19, seventeen had mothers who were also positive for COVID-19 within seven days before or after the birth. Only two cases were thought to be directly passed to the baby during pregnancy. 

The study reports that approximately 300 mothers with confirmed COVID-19 infection gave birth during this time period and most remained with their babies after birth. Seven babies who were separated from their mothers still contracted COVID-19.

How Newborns Get COVID-19

These rates suggest that it is best to keep mother and baby together where possible because separation for the purposes of trying to avoid infection is not effective. 

From the data, researchers reviewed how babies became infected and when, which babies were most likely to get COVID-19, what COVID-19 looked like in babies, what treatment they needed, and how quickly they recovered. 

Study co-author Dr Christopher Gale agrees and says,  “Keeping mother and her newborn baby together and encouraging breastfeeding, even if the mother has COVID-19, is safe – this supports international guidance from the World Health Organisation.”

Of the 66 positive COVID-19 babies, 34 had a close contact or family member who had signs and symptoms of COVID-19 (but not necessarily a confirmed case). 

These results show the importance of avoiding contact with anyone who is unwell with any symptoms of COVID-19, no matter how mild.

No one should visit baby if they are having a fever, cough, runny nose, or any other symptoms concerning for COVID. Encouraging visitors to wash hands can reduce the spread of infections, and some families may opt to have visitors wear a mask if they are holding the newborn.

Dr Patrick Clements, medical director of the Well Baby Unit at Riley Children’s Health, reminds new parents to avoid contact with anyone who is unwell “No one should visit baby if they are having a fever, cough, runny nose, or any other symptoms concerning for COVID. Encouraging visitors to wash hands can reduce the spread of infections, and some families may opt to have visitors wear a mask if they are holding the newborn.”

Eight of the confirmed newborn cases were thought to be hospital-acquired infections. None of these babies had mothers with COVID-19 and most of them were in a neonatal unit or pediatric intensive care unit for reasons other than COVID-19. 

What COVID-19 Looks Like in Newborns

Not all babies showed signs of infection. Babies who were tested within seven days of birth because of maternal infection usually showed no symptoms prior to testing. 

Babies who did show symptoms most commonly had fevers, poor feeding, and signs of a cold such as nasal stuffiness, discharge, and inflammation of the mucosa in the nose or throat. Lethargy and respiratory distress were also commonly reported.

Respiratory distress is when you see the skin between and around the ribs sinks in with an inhale. Other things you may notice include very rapid breathing (more than 60 breaths per minute), nostrils flaring out with every inhale, or a small noise with every exhale.

Of these 66 COVID-19 positive babies, 28 were classified as ‘severe’ COVID-19, which means they had symptoms as mentioned above, but they also had abnormal chest x rays or abnormal blood test results consistent with more serious cases of COVID-19.  

What This Means for You

If your newborn baby shows any of these signs, or you are concerned about your baby for any reason it is important to seek medical care: 


  • Fever equal to or greater than 100.4 degrees F (37.9 degrees C)
  • Any signs of respiratory distress 
  • Poor feeding
  • Lethargy
  • Nasal stuffiness or discharge
  • Cough
  • Poor tone (floppiness)
  • Persistent body temperature below 97.7 degrees F (36.5 degrees C)

Onset of COVID-19 in Newborns

For babies who had mothers with COVID-19, babies were generally diagnosed with COVID-19 within seven days of birth. It is important to note that these babies were being tested even if they did not show symptoms.

For babies who had a hospital-acquired COVID-19 infection, most of these babies showed symptoms and were diagnosed after seven days of birth. 

The majority of babies with severe COVID-19 infection were diagnosed 10-12 days after birth. However, some babies were diagnosed as late as 28 days after birth. 

This data suggests that the incubation period for COVID-19 in newborns is the same as the general population. Seattle Children's Hospital defines the incubation period as 2-14 days after exposure. 

Treatment and Recovery of Newborns with COVID-19 

The majority of babies who had COVID-19 were term babies who were cared for in a pediatric or postnatal hospital ward and kept with their mother. On average, these babies were discharged home after 2 days in hospital with no further support needed.

Babies admitted to a pediatric intensive care unit also stayed an average of 2 days before discharge. Babies in neonatal units generally stayed longer, but this is likely due to prematurity rather than COVID-19.

22 of the 66 babies required additional support with breathing. Of these 22, only three required invasive ventilation, ten required non-invasive ventilation, and all of these babies received supplemental oxygen. Five of these 22 babies were born preterm which means that their oxygen requirement may have been needed even if they did not have COVID-19.

While about 1 in 3 of these babies needed some breathing support … these babies did very well. No baby died of SARS-CoV-2 in this study.

Gale reports, “While about 1 in 3 of these babies needed some breathing support (mainly just with oxygen, and some may have needed this for other reasons like prematurity) these babies did very well. No baby died of SARS-CoV-2 in this study.”

Other treatments provided included 2 instances of antiviral therapy, 2 instances of corticosteroids and one instance of immunoglobulin therapy. There is no evidence in this study about the effect of these therapies. 

Newborns Most at Risk

Researchers report an over-representation of premature babies with COVID-19. The exact reasons are not known, but it may be due to altered immune function in premature babies which causes them to be more susceptible to infections. 

There was also a large proportion of hospital-acquired COVID-19 infections that occurred in the neonatal units, suggesting that hospitals need to reconsider their infection control protocols in relation to this COVID-19 data. 

36 COVID-19 positive babies were of white ethnic groups, 14 were from Asian ethnic groups, 8 were from Black ethnic groups, and 7 were from other Minority Ethnic groups. 

Although it appears that the white ethnic groups were the highest prevalence, when calculated against the total number of live births from each of these ethnic groups, newborns of BAME populations had a higher incidence of COVID-19 infection. 

The higher incidence of COVID-19 in BAME populations is consistent across all age groups. It may be due to higher BAME population numbers that live in locations of an outbreak, but researchers admit that the true reasons are unknown and that more research is urgently needed in this area.

What to do if you suspect COVID-19 in your baby 

If you are worried that your baby has been exposed to COVID-19, monitor them for signs and symptoms of the illness. If your baby shows any signs of illness it is best to see your doctor or local hospital for advice as soon as possible. 

Clements suggests, “Contact your child's doctor if there is ever a concern. Newborns should be monitored for fever. In babies, a fever is a temperature of 100.4F. Any time a baby has a fever they should see their regular doctor right away, or come to the emergency department at the hospital.”

"Families should also monitor baby for signs of breathing problems. If baby is breathing very fast, using the muscles between the ribs to breathe (retractions), or looking like they are having difficulty they should seek medical care right away."

If you suspect your baby has been exposed to COVID-19, phone ahead so that staff can be ready to attend appropriately. Clements reminds parents that “If there is concern for COVID-19, healthcare workers will wear special protective equipment when they are caring for baby.” 

How to Protect Your Baby


Regular hand washing, especially before and after feeds or diaper changes is very important. 

If a mother has COVID-19, Clements also advises “the best way to keep the baby safe is to protect the baby from infectious respiratory particles. This means distancing from baby when possible. Any time mother is less than 6 feet away from baby, she should wear her mask.”

Breastfeeding is considered safe with COVID-19 and is encouraged by the World Health Organization

Avoid contact with people who are unwell. If a member of the household is unwell, cleaning surfaces such as benchtops, taps and door handles regularly is important. It is also important to try to keep those people away from the baby where possible. 

Keeping your circle of contacts limited is advised, but very challenging for new parents. Support networks are so important for parents with a newborn.

Clements reminds parents to reach out to their doctor if they are feeling overwhelmed. He also offers some suggestions for friends and family to offer support to new parents from a distance. 

“I encourage families to get creative in keeping in contact with family and friends, such as having a grandparent read a book over video to an older child while mother breastfeeds baby.  Or involved family and friends with delivering groceries or meals to the home.”

Overall, parents can rest assured that the risk of newborns getting COVID-19 is very low. None-the-less, all necessary precautions such as hand washing, social distancing, and avoiding contact with unwell people should still be followed.
