Most people who get coronavirus disease 2019 (COVID-19) recover within a few weeks. But some people — even those who had mild versions of the disease — might have symptoms that last a long time afterward.
These ongoing health problems are sometimes called post-COVID-19 syndrome, post-COVID conditions, long COVID-19, long-haul COVID-19, and post acute sequelae of SARS COV-2 infection (PASC).
COVID-19 syndrome involves a variety of new, returning or ongoing symptoms that people experience more than four weeks after getting COVID-19. In some people, post-COVID-19 syndrome lasts months or years or causes disability.
