Types of Post-COVID Conditions


New or Ongoing Symptoms

Some people experience a range of new or ongoing symptoms that can last weeks or months after first being infected with the virus that causes COVID-19. Unlike some of the other types of post-COVID conditions that tend only to occur in people who have had severe illness, these symptoms can happen to anyone who has had COVID-19, even if the illness was mild, or if they had no initial symptoms. People commonly report experiencing different combinations of the following symptoms:

  • Difficulty breathing or shortness of breath

  • Tiredness or fatigue

  • Symptoms that get worse after physical or mental activities (also known as post-exertional malaise)

  • Difficulty thinking or concentrating (sometimes referred to as “brain fog”)

  • Cough

  • Chest or stomach pain

  • Headache

  • Fast-beating or pounding heart (also known as heart palpitations)

  • Joint or muscle pain

  • Pins-and-needles feeling

  • Diarrhea

  • Sleep problems

  • Fever

  • Dizziness on standing (lightheadedness)

  • Rash

  • Mood changes

  • Change in smell or taste

  • Changes in menstrual period cycles

Multi-organ Effects of COVID-19

Some people who had severe illness with COVID-19 experience multiorgan effects or autoimmune conditions over a longer time with symptoms lasting weeks or months after COVID-19 illness. Multiorgan effects can affect many, if not all, body systems, including heart, lung, kidney, skin, and brain functions. Autoimmune conditions happen when your immune system attacks healthy cells in your body by mistake, causing inflammation (swelling) or tissue damage in the affected parts of the body. While it is very rare, some people, mostly children, experience multisystem inflammatory syndrome (MIS) during or immediately after a COVID-19 infection. MIS is a condition where different body parts can become inflamed. MIS can lead to post-COVID conditions if a person continues to experience multiorgan effects or other symptoms.

Effects of COVID-19 Illness or Hospitalization Hospitalizations and severe illnesses for lung-related diseases, including COVID-19, can cause health effects like severe weakness and exhaustion during the recovery period. Effects of hospitalization can also include post-intensive care syndrome (PICS), which refers to health effects that begin when a person is in an intensive care unit (ICU) and can remain after a person returns home. These effects can include severe weakness, problems with thinking and judgment, and post-traumatic stress disorder (PTSD). PTSD involves long-term reactions to a very stressful event.

Some symptoms that can occur after hospitalization are similar to some of the symptoms that people with initially mild or no symptoms may experience many weeks after COVID-19. It can be difficult to know whether they are caused by the effects of hospitalization, the long-term effects of the virus, or a combination of both. These conditions might also be complicated by other effects related to the COVID-19 pandemic, including mental health effects from isolation, negative economic situations, and lack of access to healthcare for managing underlying conditions. These factors have affected both people who have experienced COVID-19 and those who have not.


Children and Adolescents A person of any age who has had COVID-19 can later develop a post-COVID condition. Although post-COVID conditions appear to be less common in children and adolescents than in adults, long-term effects after COVID-19 do occur in children and adolescents. Studies have reported long-term symptoms in children with both mild and severe COVID-19, including children who previously had multisystem inflammatory syndrome in children. Similar to the symptoms seen in adults, the most common symptoms reported have been tiredness or fatigue, headache, trouble sleeping (insomnia), trouble concentrating, muscle and joint pain, and cough. Young children may have trouble describing the problems they are experiencing; information on post-COVID conditions in children and adolescents is limited. It is possible that other symptoms may be likely in younger age groups.

If your child has a post-COVID condition that impacts their ability to attend school, complete schoolwork, or perform their usual activities, it may be helpful to discuss with your child’s school possible accommodations such as extra time on tests, scheduled rest periods throughout the day, a modified class schedule, etc. School administrators, school counselors, and school nurses can work with families and healthcare professionals to provide learning accommodations for children with post-COVID conditions, particularly those experiencing thinking, concentrating, or physical difficulties. You may also request similar accommodations for activities outside of school, such as day care, tutoring, sports, scouting, etc.
