Post-COVID Conditions in Children and Teens

Millions of U.S. children and teens have tested positive for SARS-CoV-2, the virus that causes COVID-19. Fortunately, they have been less likely than adults so far to become very ill. However, even if they had few or no symptoms, kids can develop a number of other conditions after the COVID infection. Some are minor and may go away on their own. Others are more serious and may need treatment.

If your child tests positive for COVID-19, talk with your child’s doctor about watching for lingering or new symptoms, and what to do if you notice any. Your pediatrician also can help guide your child’s safe return-to-activities such as school, sports, camp, jobs, and volunteer activities.

Symptoms and conditions that can affect children after COVID-19

  • Breathing problems. Because COVID-19 most often affects the lungs, lingering respiratory symptoms are not uncommon. These may include chest pain, cough, and more trouble breathing during exercise. Some of these symptoms can last for 3 months or longer. Children 6 years or older with lasting symptoms may need lung function tests. Children with exercise-induced breathing problems that don’t go away may need heart tests to rule out complications such as blood clots.

  • Cardiac issues. Myocarditis, an inflammation of the heart muscle, can develop after COVID-19 (and in extremely rare cases, receiving mRNA vaccines). One study of adult patients who recently recovered from COVID-19 suggested that 60% of them had myocarditis, regardless of how severe their COVID symptoms were during the infection. Symptoms of myocarditis may include chest pain, shortness of breath, irregular heartbeat, and fatigue. Children and teens who had moderate or severe symptoms within the last 6 months need an thorough exam, including heart tests, before returning to school or sports activities.

  • Smell and taste. As many as 1 out of 4 children and teens age 10 to 19 years of age who had COVID experience changes to their sense of smell and taste. This can have a negative effect on their eating habits and mood. It can also prevent them from noticing dangerous odors. These symptoms typically go away in several weeks. When it doesn’t, your child’s doctor may recommend steps to test or help retrain these senses.

  • Developmental issues. Active COVID-19 illness can affect the nervous system and, in rare cases, lead to stroke or encephalitis (brain swelling). Children who’ve had COVID-19 may experience subtle changes in attention, speech, school work, movement and mood. Your pediatrician may refer you for follow up with a neurodevelopmental specialist, a speech language pathologist, or physical or occupational therapists.

  • Mental fatigue. "Brain fog"—unclear or "fuzzy" thinking, concentration, or memory—is a frequent complaint among adults who’ve had COVID-19. Children and teens may have similar symptoms. Your child may seem more forgetful or have trouble paying attention. They may be slower at reading and need more repetition and breaks while learning. Make sure your child get enough sleep and help them manage stress, which can worsen these symptoms worse. If post-COVID mental fatigue doesn’t improve or interferes with daily activities, your child may benefit from a team-based treatment and recovery plan.

  • Physical fatigue. After SARS-CoV-2 infection, children and teens may tire more easily and have less physical endurance, even if they had no heart or lung symptoms from the virus. This usually improves over time. Your pediatrician can advise a gradual increase in physical activity. If this doesn't improve symptoms, they may recommend a visit to a physical therapist or other specialist.

  • Headaches. Headache is a common symptom during and following SARS-CoV-2 infection. Getting enough sleep, drinking plenty of water, eating regular meals, and managing stress can help. If the headaches are lasting and severe enough, your child's doctor may recommend preventive medicines.

  • Mental and behavioral health. Having had COVID-19 can affect a child’s mental health. For children with existing mental/behavioral illness, events surrounding COVID-19 (hospitalization, isolation, absence from school activities) may also make symptoms worse. Your pediatrician can check your child for signs of depression, anxiety, and other mental health concerns, and advise when your child may need more support.

  • Multisystem inflammatory syndrome in children (MIS-C) is a rare complication that typically happens 2 to 4 weeks after SARS-CoV-2 infection. Talk with your pediatrician if your child has symptoms such as fever without an obvious cause after having COVID-19 or being exposed to someone who did. MIS-C can get worse quickly, and children who develop this condition should be cared for in a pediatric/cardiac intensive care unit (PICU) whenever possible.

  • Long-haul COVID-19 is a general term that covers physical and mental health symptoms some patients experience 4 or more weeks after SARS-CoV-2 infection. No specific lab test can tell "long-haul COVID-19" apart from other conditions. For the first 4 to 12 weeks after illness, focusing mostly on healthy lifestyle approaches to help improve symptoms is usually best. If symptoms last beyond 3 months, your child’s doctor may recommend additional tests and possible referral to a specialized, multidisciplinary post-COVID-19 clinic.

Remember

All children and teens should get fully immunized against COVID-19 as soon as they are eligible to prevent SARS-C0V-2 infection. If your child tests positive for COVID-19, talk with your pediatrician about possible concerns, how to address them, and ways to help your child return safely to their normal activities.
