Many people recover fully within a few days or weeks after being infected with SARS-CoV-2, the virus that causes COVID-19. However, others have symptoms that linger for weeks, months, or even years after their initial diagnosis. Some people seem to recover from COVID-19 but then see their symptoms return, or they develop different symptoms within a few months. Even people who had no symptoms when they were infected can develop them later. Either mild or severe COVID-19 can lead to long-lasting symptoms.

Long COVID, long-haul COVID, post-COVID-19 condition, chronic COVID, and post-acute sequelae of SARS-CoV-2 (PASC) are all names for the health problems that some people experience a few months after a COVID-19 diagnosis. Symptoms of Long COVID may be the same as or different than symptoms of COVID-19. Long COVID can also trigger other health conditions such as diabetes or kidney disease.
