What is long COVID?

Long COVID is a term used to describe ongoing effects of COVID-19 infection. Signs and symptoms are considered long COVID if they begin or continue at least 4 weeks after the infection. Experts believe the immune system in some people overreacts to the virus that causes COVID-19. The immune system attacks the virus, but it also attacks healthy nerves, blood vessels, and organs. It is not yet known how long symptoms could continue. Anyone who had COVID-19 can develop long COVID, even if symptoms were mild or never developed at all. Long COVID may also be called post-COVID conditions, post-acute COVID, or chronic COVID. Long-term effects caused by the virus may also be called post-acute sequelae of SARS-CoV-2 (PASC).
