COVID-19 in babies and children

By Mayo Clinic Staff

Children of all ages can get the coronavirus disease 2019 (COVID-19) and experience its complications.

Know the possible symptoms of COVID-19 in children and what you can do to protect your child.

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

Children represent about 19% of all reported COVID-19 cases in the U.S. since the pandemic began.

While children are as likely to get COVID-19 as adults, kids are less likely to become severely ill. Up to 50% of children and adolescents might have COVID-19 with no symptoms. However, some children with COVID-19 need to be hospitalized, treated in the intensive care unit or placed on a ventilator to help them breathe.

Certain medical conditions might increase a child's risk of serious illness with COVID-19, including:

  • Obesity
  • Diabetes
  • Asthma
  • Congenital heart disease
  • Genetic conditions
  • Conditions affecting the nervous system or metabolism

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

How are babies affected by COVID-19?

Babies under age 1 might be at higher risk of severe illness with COVID-19 than older children.

Newborns can get 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 during your stay in the hospital after childbirth, wear a well-fitting 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 maintain a reasonable distance from your baby when possible. When these steps are taken, the risk of a newborn getting COVID-19 is low. However, if you are severely ill with COVID-19, you might need to be temporarily separated from your newborn.

Infants who have COVID-19 but no symptoms might be sent home 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.

What are the signs and symptoms of COVID-19 in children?

Children with COVID-19 might have many symptoms, only a few symptoms or no symptoms. The most common symptoms of COVID-19 in children are cough and fever. Possible signs and symptoms include:

  • Fever
  • Cough that becomes productive
  • Chest pain
  • New loss of taste or smell
  • Changes in the skin, such as discolored areas on the feet and hands
  • Sore throat
  • Nausea, vomiting, belly pain or diarrhea
  • Chills
  • Muscle aches and pain
  • Extreme fatigue
  • New severe headache
  • New nasal congestion

COVID-19 symptoms appear on average about 6 days after a COVID-19 exposure. It can be hard to tell if your child has COVID-19 or another illness with similar symptoms, such as the flu or hay fever.

If you think your child might have COVID-19:

  • Talk to your child's health care provider.
  • Keep your child at home and away from others, except to get medical care. If possible, have your child use a separate bedroom and bathroom.
  • Follow recommendations from the Centers for Disease Control and Prevention (CDC) and your government regarding quarantine and isolation measures, as needed.
  • Focus on symptom relief. This might include rest, plenty of fluids and use of pain relievers.
  • Call the doctor if your child keeps getting sicker. Emergency warning signs include trouble breathing, persistent pain or pressure in the chest, new confusion, inability to wake or stay awake, or pale, gray, or blue-colored skin, lips or nail beds — depending on your child's skin tone.

Factors used to decide whether to test your child for COVID-19 may differ depending on where you live. In the U.S., a health care provider will determine whether to conduct diagnostic tests for COVID-19 based on your child's symptoms, as well as whether your child has had close contact with someone diagnosed with COVID-19. A health care provider 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.

Jennifer Rodemeyer, Child Life Program Manager, Mayo Clinic: Hi, I'm Jennifer and I am a child life specialist at Mayo Clinic. My job is to help kids like you prepare for medical tests.

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.

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 excessive immune response 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
  • Pale, gray or blue-colored skin, lips or nail beds — depending on skin tone
  • 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 health care provider right away for advice.

Can children who get COVID-19 experience long-term effects?

Anyone who has had COVID-19 can develop a post-COVID-19 condition. Research suggests that children with both mild and severe COVID-19 have experienced long-term symptoms. The most common symptoms in children include:

  • Tiredness or fatigue
  • Headache
  • Trouble sleeping
  • Trouble concentrating
  • Muscle and joint pain
  • Cough

These symptoms could affect your child's ability to attend school or do his or her usual activities. If your child is experiencing long-term symptoms, consider talking to your child's teachers about his or her needs.

If children don't frequently experience severe illness with COVID-19, why do they need a COVID-19 vaccine?

A COVID-19 vaccine can prevent your child from getting COVID-19 and spreading it at home and in school.

If your child gets COVID-19, a COVID-19 vaccine could prevent severe illness.

Getting a COVID-19 vaccine can also help keep your child in school and more safely have playdates and participate in sports and other group activities.

What COVID-19 vaccines, additional primary shots and booster shots are available to kids in the U.S.?

In the U.S., COVID-19 vaccines are available to children by age group:

  • Ages 6 months through 4 or 5 years old. The U.S. Food and Drug Administration (FDA) has given emergency use authorization to a Pfizer-BioNTech COVID-19 vaccine for children ages 6 months through 4 years old. This vaccine requires three shots. The first two shots are given three to eight weeks apart. The third shot is given at least eight weeks after the second shot. Research shows that the three shots have produced antibody levels similar to those in young adults after getting the Pfizer-BioNTech vaccine.

    The FDA has also given emergency use authorization to a Moderna COVID-19 vaccine for children ages 6 months through 5 years old. This vaccine requires two shots, given four to eight weeks apart. It’s estimated that this vaccine is about 51% effective in preventing COVID-19 in babies ages 6 months through 23 months. For kids ages 2 through 5 years old, the vaccine is estimated to be 37% effective in preventing COVID-19.

    Both vaccines contain lower amounts of mRNA than the mRNA COVID-19 vaccines for older children and adults.

  • Ages 5 or 6 through 11. The FDA has given emergency use authorization to a Pfizer-BioNTech COVID-19 vaccine for children ages 5 through 11. This vaccine involves two shots, given three weeks apart. It contains a lower amount of mRNA than the Pfizer-BioNTech COVID-19 vaccine used for people age 12 and older. This vaccine is about 91% effective in preventing COVID-19 in children ages 5 through 11.

    The FDA has also given emergency use authorization to a Moderna COVID-19 vaccine for children ages 6 through 11. This vaccine requires two shots, given four to eight weeks apart. For kids in this age group, the Moderna vaccine causes an immune response similar to that seen in adults.

    Both vaccines contain lower amounts of mRNA than the COVID-19 vaccines for people age 12 and older.

  • Ages 12 through 17. The FDA has given emergency use authorization to a Pfizer-BioNTech COVID-19 vaccine for children ages 12 through 15. This vaccine involves two shots. The second shot can be given three to eight weeks after the first shot. It contains the same amount of mRNA as the Pfizer-BioNTech COVID-19 vaccine for people age 16 and older. This vaccine is 100% effective in preventing COVID-19 in children ages 12 through 15.

    The FDA has approved a Pfizer-BioNTech COVID-19 vaccine, now called Comirnaty, for people age 16 and older. This vaccine involves two shots. The second shot can be given three to eight weeks after the first shot. This vaccine is 91% effective in preventing severe illness with COVID-19 in people age 16 and older.

    The FDA has also given emergency use authorization to a Moderna COVID-19 vaccine for children ages 12 through 17. This vaccine requires two shots, given four to eight weeks apart. It contains the same amount of mRNA as the Moderna COVID-19 vaccine for people age 18 and older. For kids ages 12 through 17, the Moderna COVID-19 vaccine causes an immune response similar to that seen in adults.

The shortest interval between the first and second doses of mRNA COVID-19 vaccines is still recommended for people who have weakened immune systems and others who need rapid protection due to concern about community transmission or risk of severe illness. An eight-week interval between the first and second doses might be best for some people, especially males ages 12 to 39. A longer interval might increase protection against COVID-19 and reduce the risk of rare heart problems, such as myocarditis and pericarditis.

An additional primary shot of a COVID-19 vaccine can help people who are vaccinated and might not have had a strong enough immune response. The CDC recommends that children ages 5 and older who have moderately or severely weakened immune systems should get an additional dose of the Pfizer-BioNTech COVID-19 vaccine or the Moderna COVID-19 vaccine. This shot should be given at least four weeks after the second shot.

Booster doses can help people who are vaccinated and whose immune response weakened over time. Research suggests that getting a booster dose can decrease the risk of infection and severe illness with COVID-19.

Kids ages 5 through 17 should get a Pfizer-BioNTech COVID-19 vaccine booster shot if they have been given both doses of a Pfizer-BioNTech COVID-19 vaccine and it’s been at least five months.

Kids ages 5 through 17 who have a weakened immune system should get a Pfizer-BioNTech COVID-19 vaccine booster shot if they have been given both doses of the Pfizer-BioNTech COVID-19 vaccine and it’s been at least three months since the additional primary shot.

Kids age 12 and older who have a weakened immune system, got both doses of the Pfizer-BioNTech COVID-19 vaccine and got a single booster dose of the Pfizer-BioNTech COVID-19 vaccine at least four months ago can also get a second booster dose of the Pfizer-BioNTech COVID-19 vaccine.

Currently, booster doses aren’t recommended for any children or teens who get the Moderna COVID-19 vaccine for their first two doses.

What can I do to prevent my child from getting COVID-19?

There are many steps you can take to prevent your child from getting the COVID-19 virus and spreading it to others. The CDC recommends:

  • Getting vaccinated. COVID-19 vaccines reduce the risk of getting and spreading COVID-19. A COVID-19 vaccine can be given to eligible children on the same day as other vaccines.
  • Wearing face masks. If you are in an area with a high number of people with COVID-19 in the hospital or new COVID-19 cases, the CDC recommends wearing a well-fitted mask indoors in public, whether or not you're vaccinated. Don't place a face mask on a child younger than age 2 or a child with a disability who can't safely wear a mask.
  • Keeping hands clean. Encourage frequent handwashing with soap and water for at least 20 seconds, or using an alcohol-based hand sanitizer that contains at least 60% alcohol. Have your child cover his or her mouth and nose with an elbow or a tissue when coughing or sneezing. Remind your child to avoid touching his or her eyes, nose and mouth. Teach your kids to keep washing their hands until they have sung the entire "Happy Birthday" song twice (about 20 seconds).
  • Cleaning and disinfecting your home. Clean high-touch surfaces and objects regularly and after you have visitors in your home. Also, regularly clean areas that easily get dirty, such as a baby's changing table, and surfaces and items that your child often touches.
  • Choosing safer activities. Choose outdoor activities when possible or indoor activities in well-ventilated spaces. Avoid activities that make it hard to stay 6 feet, or 2 meters, away from others. Limit visits with people who are unvaccinated or whose vaccination status is unknown. Keep distance between your child and others when in public. Avoid close contact with people who are sick, if possible.

In addition, keep up with well-child visits and your child's other vaccines — especially if your child is under age 2. If your child is due for a checkup and you're concerned about exposure to COVID-19, talk to your child's doctor about safety steps being taken. Don't let fear of getting COVID-19 prevent your child from getting vaccines to prevent other serious illnesses.

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