COVID-19 in babies – here’s what to expect

Victoria: Parents are understandably worried about what would happen if their infant caught COVID-19. Babies may be considered vulnerable due to immature immune systems, and are also not eligible for most of the treatments and vaccinations available for older children and adults.

The good news is, that most babies experience mild illness. Here’s what to expect if your baby tests positive.

If you test positive and have a newborn or infant at home, there are some protective steps you can take. These include hand-washing before providing care, and wearing a mask when breastfeeding or in close contact. Current evidence suggests COVID-19 cannot be spread through breastmilk.

It’s still really important to continue breastfeeding (if you do so already) and there is no need to separate mother and baby.

Transmission from older siblings and other close contacts may also be reduced by vaccination. Vaccination of parents and caregivers will also reduce their chance of severe disease, thereby minimizing the risks and interruptions for mother and baby.

Testing your baby is similar to testing yourself. Babies can often get PCR tests in the same places where they will be tested, or you can use a rapid antigen test (RAT) on them.

If you are using a RAT it’s important to check it’s for the correct age group, as not all RATs can be used on children. It will say on the packet whether it is suitable. Otherwise, ask your pharmacist for the correct test for your child’s age.

It’s also important to follow the specific instructions for the test you have purchased, as not all will be the same.

Throughout the pandemic, children of all ages have been less likely to experience severe disease compared with adults. The likelihood of severe disease also appears to be lower with Omicron compared with previous variants, although the transmission of later variants has been higher.

From our clinical experience and international research, babies with COVID-19 have mostly had mild disease. The need for hospitalization or intensive care is extremely uncommon. Babies may be at higher risk if they are premature or have another underlying serious illness or condition. Studies describing COVID-19 in newborns reflect that similar to other respiratory viruses like influenza and RSV, deaths are very rare.

A range of immune differences in newborns has been proposed to explain why babies usually get the less severe disease. While there is no vaccine for infants, antibodies transfer from mothers who have been vaccinated while pregnant to newborns, which may offer protection.

Babies may exhibit a range of symptoms when they have COVID-19 that are typical of other respiratory viruses. Up to 25 percent of babies may have no symptoms.

Fever, nasal congestion, feeding difficulties, and cough are more common symptoms.

Breathing difficulties, lethargy, and persistent fever may be signs of severe disease.

You can give your baby paracetamol or ibuprofen if there is fever or discomfort, and nasal saline drops can ease congestion. If you are considering giving medication to an infant under three months of age, please consult your GP.

Talk to your doctor if your baby has any of the following: difficulty breathing; persistent fever feeding difficulties impacting hydration or causing less than 50 percent of a normal number of nappies.

It is important to note any fever in a newborn up to three months of age require a medical review, regardless of whether the baby has COVID.

Anything else I should know? Especially as we enter winter, protecting against other common circulating viruses which can affect babies, such as influenza, is also important. Children above six months of age can receive the influenza vaccine.
