Before we begin: Anyone who had COVID-19 can have ongoing symptoms. Learn about post-COVID conditions (long COVID), including symptoms, diagnosis, treatments, and prevention.
This tutorial walks you through everything you need to know about post-covid conditions (long covid). We explain it in plain language, step by step, so whether you are a student, a patient, or simply curious, you will come away with a solid understanding.
We cover what it is, why it matters, how it is diagnosed, and what you can do about it. Key facts are called out along the way.
What are post-COVID conditions (long COVID)? COVID-19 (coronavirus disease 2019) is an illness caused by a virus. Many people get better within a few days or weeks after being infected with the virus. But others have post-COVID conditions. They may:
Have symptoms that linger for weeks, months, or even years
Seem to recover from COVID-19 but then see their symptoms return
Develop new symptoms or new health conditions within a few months of having COVID-19
There are several other names for post-COVID conditions. It is often called long COVID. But it can also be called long-haul COVID, long-term effects of COVID, chronic COVID, post-acute COVID-19, and post-acute sequelae of SARS-CoV-2 (PASC).
Who is more likely to develop post-COVID conditions (long COVID)? Anyone who had COVID-19, whether it was severe or mild, can have long-lasting symptoms. But you are at higher risk of post-COVID conditions if you:
Had severe COVID-19 illness, especially if you were hospitalized or needed intensive care.
Had underlying health conditions before you got COVID-19.
Did not get a COVID-19 vaccine.
Had multisystem inflammatory syndrome (MIS) during or after COVID-19. MIS is a rare but serious condition in which different body parts become inflamed.
What are the symptoms of post-COVID conditions (long COVID)? Post-COVID conditions do not affect everyone the same way. They can cause various types and combinations of symptoms in different people. The symptoms may affect different parts of the body, for example:
General symptoms, such as fatigue and fever
Respiratory symptoms, such as trouble breathing and cough
Heart symptoms, such as chest pain and palpitations
Neurologic symptoms such as trouble thinking and concentrating (“brain fog”), headaches, and sleep problems
Digestive symptoms such as diarrhea and stomach pain
Some people may have a wide variety of symptoms that are similar to those of other conditions, such as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).
Most people’s symptoms slowly improve over time. But for some people, the symptoms can last weeks, months, or longer. Sometimes the symptoms are severe enough to result in disability.
How are post-COVID conditions (long COVID) diagnosed? There is no specific test for post-COVID conditions. To find out if you have a post-COVID condition, your provider:
Will ask about your medical history. This includes asking if you have had a diagnosis of COVID-19, either based on a positive test, symptoms, or exposure.
Will do a physical exam.
May order blood and imaging tests.
Some of the symptoms of post-COVID conditions may be hard to explain. The results of blood and imaging tests may be normal. And people who have unexplained symptoms may sometimes be misunderstood by their providers. So it can take some time to get a diagnosis.
What are the treatments for post-COVID conditions (long COVID)? There is no specific treatment for post-COVID conditions yet. You and your provider can work together to create a personal care plan to manage your symptoms and improve your quality of life.
Can post-COVID conditions (long COVID) be prevented? The best way to prevent post-COVID conditions is to avoid getting COVID-19. Staying up to date with vaccines (including boosters) against COVID-19 can help prevent COVID-19 infection and protect against severe illness.
Also known as: Chronic COVID, Long-haul COVID, Long-term effects of COVID.
