Some people who have been infected with the virus that causes COVID-19 can experience long-term effects from their infection. This has come to be known as post-COVID conditions or long COVID. 

People call post-COVID conditions by many names, including: long COVID, long haul COVID, post-acute COVID-19, post-acute sequelae of SARS CoV-2 infection (PASC), long-term effects of COVID, and chronic COVID. 

Long COVID can include a wide range of ongoing health problems; these conditions can last weeks, months, or years.
