COVID-19 (coronavirus) in babies and children

By Mayo Clinic Staff

Children of all ages can become ill with coronavirus disease 2019 (COVID-19). But most kids who are infected typically don't become as sick as adults and some might not show any symptoms at all. Know the symptoms of COVID-19 in babies and children, why children might be affected differently by COVID-19 and what you can do to prevent the spread of the virus.

How likely is it for a child to become sick with coronavirus disease 2019 (COVID-19)?

While all children are capable of getting the virus that causes COVID-19, they don't become sick as often as adults. Most children have mild symptoms or no symptoms.

According to the American Academy of Pediatrics and the Children's Hospital Association, in the United States children represent about 10% of all COVID-19 cases. Research suggests that children younger than ages 10 to 14 are less likely to become infected with the virus that causes COVID-19 compared to people age 20 and older. Hospitalization rates for children are also much lower than for adults. However, if children are hospitalized, they need to be treated in the intensive care unit as often as hospitalized adults, according to research from the Centers for Disease Control and Prevention (CDC).

In addition, children with underlying conditions, such as obesity, diabetes and asthma, are at higher risk of serious illness with COVID-19. Children who have congenital heart disease, genetic conditions or conditions affecting the nervous system or metabolism are also at higher risk of serious illness with COVID-19.

Research also suggests disproportionately higher rates of COVID-19 in Hispanic and non-Hispanic Black children than in non-Hispanic white children. Hispanic and non-Hispanic Black children also have had higher rates of hospitalization.

Rarely, some children might also develop a serious condition that appears to be linked to COVID-19.

Why do children react differently to COVID-19?

The answer isn't clear yet. Some experts suggest that children might not be as severely affected by COVID-19 because there are other coronaviruses that spread in the community and cause diseases such as the common cold. Since children often get colds, their immune systems might be primed to provide them with some protection against COVID-19. It's also possible that children's immune systems interact with the virus differently than do adults' immune systems. Some adults are getting sick because their immune systems seem to overreact to the virus, causing more damage to their bodies. This may be less likely to happen in children.

How are babies affected by COVID-19?

Although rare, children under age 1 appear to be at higher risk of severe illness with COVID-19 than older children. This is likely due to their immature immune systems and smaller airways, which make them more likely to develop breathing issues with respiratory virus infections.

Newborns can become infected with the virus that causes COVID-19 during childbirth or by exposure to sick caregivers after delivery. If you have COVID-19 or are waiting for test results due to symptoms, it's recommended during hospitalization after childbirth that you wear a cloth face mask and have clean hands when caring for your newborn. Keeping your newborn's crib by your bed while you are in the hospital is OK, but it's also recommended that you maintain a reasonable distance from your baby when possible. When these steps are taken, the risk of a newborn becoming infected with the COVID-19 virus is low. Research suggests that only about 2% to 5% of infants born to women with COVID-19 near the time of delivery test positive for the virus in the days after birth. However, if you are severely ill with COVID-19, you might need to be temporarily separated from your newborn.

Infants who have COVID-19 or who can't be tested due to a lack of availability and have no symptoms might be discharged from the hospital, depending on the circumstances. It's recommended that the baby's caregivers wear face masks and wash their hands to protect themselves. Frequent follow-up with the baby's health care provider is needed — by phone, virtual visits or in-office visits — for 14 days. Infants who test negative for COVID-19 can be sent home from the hospital.

Children's COVID-19 symptoms

While children and adults experience similar symptoms of COVID-19, children's symptoms tend to be mild and cold-like. Most children recover within one to two weeks. Possible symptoms can include:

  • Fever
  • Nasal congestion or runny nose
  • Cough
  • Sore throat
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Headache
  • Muscle aches
  • Nausea or vomiting
  • Diarrhea
  • Poor feeding or poor appetite
  • New loss of taste or smell
  • Belly pain
  • Pink eye (conjunctivitis)

If your child has symptoms of COVID-19 and you think he or she might have COVID-19, call your child's health care provider. Keep your child at home and away from others as much as possible, except to get medical care. If possible, have your child use a separate bedroom and bathroom from family members. Follow recommendations from the CDC, the World Health Organization (WHO) and your government regarding quarantine and isolation measures as appropriate.

Factors used to decide whether to test your child for COVID-19 may differ depending on where you live. In the U.S., the doctor will determine whether to conduct tests for COVID-19 based on your child's signs and symptoms, as well as whether your child has had close contact with someone diagnosed with COVID-19. The doctor may also consider testing if your child is at higher risk of serious illness.

To test for COVID-19, a health care provider uses a long swab to take a sample from the back of the nose (nasopharyngeal swab). The sample is then sent to a lab for testing. If your child is coughing up phlegm (sputum), that may be sent for testing.

Supporting Your Child During COVID-19 Nasal Swab Testing

The purpose of this video is to prepare children for a COVID-19 nasal swab test, to help ease some of their potential fear and anxiety. When children are prepared to take a medical test, they become more cooperative and compliant, which creates a positive coping experience for them. This video has been made to be watched by children as young as 4 years old.

You may have heard there is a virus going around that can make people feel sick. A virus is a germ and it is so tiny you can't even see it.

Some people who get this virus can have a fever or a cough and may feel achy and tired, while some people can have this virus and not feel sick at all. People may get this virus from touching things. That's why it's important to wash your hands often with soap and water. The virus also can spread through a cough or a sneeze. So it's important to always cover your cough or sneeze.

Today, even though you may or may not be feeling sick, we will need to give you a test so we know how to best proceed with your medical care. This medical test will tell us if you have the virus.

When you go to take your test, the health care provider will wear special protective clothing. They wear this clothing to keep themselves and you safe from getting germs. They will wear a mask to cover their nose and mouth and a clear plastic shield to protect their eyes.

The most important thing you can do during your test is to sit perfectly still like a statue. To help make sure you don't move, your parent or caregiver will help keep you still and calm during your test. The health care provider needs to touch the inside of the back of your nose with a long, skinny Q-tip. To do this, you need to hold your chin up, then the health care provider will put the Q-tip in your nose for a short time to collect a sample.

While this happens you may feel like you want to push the Q-tip away, but it's really important to stay as still as possible so the health care provider can finish the test. The Q-tip will be in and out of your nose in a few seconds.

Some kids tell me that counting to 3 or taking a deep breath relaxes them before the test happens, and some tell me they like to hold on to their favorite stuffed animal or blanket. Maybe you have your own way to relax.

Remember that during the test, the most important thing to do is to keep your body perfectly still.

You may have many feelings seeing the health care provider wearing different clothing, but know this person is caring and wants to help you.

Thank you for helping us get this test done, so we know how to proceed with your medical care.

But children also might have COVID-19 and not show symptoms. This is why it's crucial to follow recommendations for preventing the spread of COVID-19.

What is multisystem inflammatory syndrome in children (MIS-C)?

Multisystem inflammatory syndrome in children (MIS-C) is a serious condition in which some parts of the body — such as the heart, lungs, blood vessels, kidneys, digestive system, brain, skin or eyes — become severely inflamed. Evidence indicates that many of these children were infected with the COVID-19 virus in the past, as shown by positive antibody test results, suggesting that MIS-C is caused by an immune system reaction related to COVID-19.

Possible signs and symptoms of MIS-C include:

  • Fever that lasts 24 hours or longer
  • Vomiting
  • Diarrhea
  • Pain in the stomach
  • Skin rash
  • Fast heartbeat
  • Rapid breathing
  • Red eyes
  • Redness or swelling of the lips and tongue
  • Feeling unusually tired
  • Redness or swelling of the hands or feet
  • Headache, dizziness or lightheadedness
  • Enlarged lymph nodes

Emergency warning signs of MIS-C include:

  • Inability to wake up or stay awake
  • Difficulty breathing
  • New confusion
  • Bluish lips or face
  • Severe stomach pain

If your child shows any emergency warning signs or is severely sick with other signs and symptoms, take your child to the nearest emergency department or call 911 or your local emergency number. If your child isn't severely ill but shows other signs or symptoms of MIS-C, contact your child's doctor right away for advice.

COVID-19 prevention tips

There are many steps you can take to prevent your child from getting the virus that causes COVID-19 and, if he or she does become sick, to avoid spreading it to others. The CDC and WHO recommend that you and your family:

  • Keep your hands clean. Wash your hands often with soap and water for at least 20 seconds. If soap and water aren't available, use a hand sanitizer that contains at least 60% alcohol. Cover your mouth and nose with your elbow or a tissue when you cough or sneeze. Throw away the used tissue and wash your hands. Avoid touching your eyes, nose and mouth. Have your kids wash their hands immediately after returning home, as well as after going to the bathroom and before eating or preparing food. Show young children how to create tiny soap bubbles by rubbing their hands together and how to get the soap between fingers and all the way to the ends of their fingers, including their thumbs and the backs of their hands. Encourage your kids to sing the entire "Happy Birthday" song twice (about 20 seconds) so they spend the time they need to get their hands clean.
  • Practice social distancing. Avoid close contact (within about 6 feet, or 2 meters) with anyone who is sick or has symptoms. Minimize trips outside your house. When you do go out, leave your children at home — if possible. Since people without symptoms can spread the virus, don't allow your child to have in-person playdates with children from other households — even if they are all feeling well. If your child plays outside, make sure he or she stays 6 feet away from people outside of your household. You can describe this distance to your child as about the length of a door or an adult's bicycle. Don't allow your child to play games or sports that involve shared equipment, such as a basketball, or that can't accommodate physical distancing. Postpone your child's in-person visits with older adults. Encourage your child to keep in touch with friends and loved ones through phone calls or video chats. Consider organizing virtual family meals, game nights or playdates to keep your child engaged.
  • Clean and disinfect your home. Focus on cleaning surfaces every day in common areas that are frequently touched, such as tables, doorknobs, hard-backed chairs, light switches, remotes, electronics, handles, desks, toilets and sinks. Also, clean areas that easily get dirty, such as a baby's changing table, and surfaces that your child often touches, such as his or her bed frame, craft table, toy chest and toys. Use soap and water to clean toys that your child puts in his or her mouth. Be sure to rinse off the soap and dry the toys. Wash your child's bedding and washable plush toys, as needed, in the warmest possible setting. Dry items completely. Wash your hands after handling your child's belongings. If you're caring for a baby with COVID-19, wash your hands after diaper changes or handling the baby's bedding, toys or bottles.
  • Wear cloth face masks. The CDC recommends wearing cloth face coverings in public places, such as the grocery store, where it's difficult to avoid close contact with others. It's especially suggested in areas with ongoing community spread. This advice is based on data showing that people with COVID-19 can transmit the virus before realizing that they have it. If your child is age 2 or older, have him or her wear a cloth face mask when out in the community to prevent the spread of COVID-19 to others. Don't place a face mask on a child younger than age 2, a child who has any breathing problems, or a child who has a condition that would prevent him or her from being able to remove the mask without help.

In addition, keep up with your child's well visits and vaccines. This is especially important for infants and young children under age 2. Many health care providers in communites affected by COVID-19 are using strategies to separate well visits from sick visits by seeing sick children in separate areas of their offices or at different locations. If your child is due for a well visit, talk to your child's doctor about safety steps being taken. Don't let fear of getting the virus that causes COVID-19 prevent your child from getting his or her vaccines to prevent other serious illnesses.

Following guidelines to prevent the spread of the COVID-19 virus can be particularly difficult for kids. Stay patient. Be a good role model and your child will be more likely to follow your lead.
