Even people who did not have COVID-19 symptoms in the days or weeks after they were infected can have long COVID conditions. These conditions can present as different types and combinations of health problems for different lengths of time. CDC and partners are working to understand more about who experiences post-COVID conditions and why, including whether groups disproportionately impacted by COVID-19 are at higher risk.

Types of long COVID Conditions


People with post-COVID conditions can have a wide range of symptoms that can last more than four weeks or even months after infection. Sometimes the symptoms can even go away or come back again.

Post-COVID conditions may not affect everyone the same way. People with post-COVID conditions may experience health problems from different types and combinations of symptoms happening over different lengths of time. Most patients’ symptoms slowly improve with time. However, for some people, post-COVID conditions may last months, and potentially years, after COVID-19 illness and may sometimes result in disability.

Multiorgan Effects of COVID-19

Some people, especially those who had severe COVID-19, experience multiorgan effects or autoimmune conditions with symptoms lasting weeks or months after COVID-19 illness. Multiorgan effects can involve many body systems, including the heart, lung, kidney, skin, and brain. As a result of these effects, people who have had COVID-19 may be more likely to develop new health conditions such as diabetes, heart conditions or neurological conditions compared with people who have not had COVID-19.

'This has honestly been a very scary journey ... I'm telling my Long COVID STORY because I wouldn't wish this on anyone.' - Isaiah, 26
'I used to run 5 to 6 miles a day. Now, when I walk up a flight of stairs, I'm gasping for air ... I'm telling my Long COVID story because I don't want it to ruin other people's lives liek it did mine.' - Rob, 22
'I can no longer remember some things that happened even way before I got COVID... I'm telling my Long COVID story so that you won't have one to tell.' - Katelny, 20

Effects of Severe Illness or Hospitalization

People experiencing any severe illness, hospitalization, or treatment may develop problems such as post-intensive care syndrome, or PICS. PICS refers to the health effects that may begin when a person is in an intensive care unit (ICU), and which may persist after a person returns home. These effects can include muscle weakness, problems with thinking and judgment, and symptoms of post-traumatic stress disorder (PTSD). PTSDexternal icon involves long-term reactions to a very stressful event. For people who experience PICS following a COVID-19 diagnosis, it is difficult to determine whether these health problems are caused by a severe illness, the virus itself, or a combination of both

People More Likely to Develop Long COVID

Researchers are working to understand which people or groups of people are more likely to have post-COVID conditions, and why. Studies have shown that some groups of people may be affected more by post-COVID conditions. These are examples and not a comprehensive list of people or groups who might be more at risk than other groups for developing post-COVID conditions:
