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. Children also rarely experience severe illness with COVID-19. Despite many large outbreaks around the world, very few children have died.
According to the U.S. Centers for Disease Control and Prevention (CDC), among nearly 150,000 cases of COVID-19 in the U.S. between Feb. 12 and April 2, only about 2,500, or 1.7%, were in children. This is similar to what has been reported in other countries, such as China and Italy, that have had large outbreaks. Hospitalization rates for children have been much lower than for adults.
However, people of any age with certain underlying conditions, such as type 2 diabetes, are at higher risk of serious illness with COVID-19. Additionally, 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.
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, they might have antibodies that 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 (infants) are at higher risk of severe illness with COVID-19. 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.
A study of more than 2,100 children with suspected or confirmed COVID-19 in China between late December and early February showed that just under 11% of infants had severe or critical illness. In comparison, rates of severe or critical illness were about 7% for children ages 1 to 5, 4% for those 6 to 10, 4% for those 11 to 15 and 3% for those 16 and older.
Newborns can become infected with the virus that causes COVID-19 during childbirth or by exposure to sick caregivers after delivery. The American Academy of Pediatrics recommends special care for newborns born to women who have confirmed or suspected COVID-19. This might include temporarily separating the mother and the newborn to decrease the risk of infecting the baby, monitoring the baby for signs of infection, and, if supplies are available, testing the newborn for COVID-19.
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. Until the mother recovers, it's recommended that she minimize close contact with the baby and use a face mask and wash her hands when she is near the baby.
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. Their symptoms can include:
- Runny nose
- Muscle aches
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 or traveled to or lived in any areas with ongoing community spread of COVID-19 in the past 14 days. 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. 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. A study of 171 children with COVID-19 in China between late January and February showed that 27 children, or nearly 16%, had no symptoms of infection. In addition, a small study of 36 children with COVID-19 in China between January and March found that nearly half of the children showed no symptoms. Some recent studies have suggested that the virus that causes COVID-19 might be spread by children and adults who aren't showing 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, blood vessels, kidneys, digestive system, brain, skin or eyes — become inflamed. Inflammation typically includes swelling, often with redness and pain. Evidence indicates that many of these children were infected with the COVID-19 virus in the past, as shown by positive antibody test results.
Possible signs and symptoms of MIS-C include:
- Fever that lasts 24 hours or longer
- Pain in the stomach
- Skin rash
- Red eyes
- Redness or swelling of the lips and tongue
- Feeling unusually tired
- Redness or swelling of the hands or feet
Emergency warning signs of MIS-C include:
- Inability to wake up or stay awake
- Difficulty breathing
- Chest pain or pressure that doesn't go away
- 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.
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.
