Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), refers to a range of symptoms that continue for weeks or months after the acute phase of a COVID-19 infection has resolved. Individuals experiencing these prolonged symptoms are often referred to as "long haulers." Common symptoms include fatigue, brain fog, shortness of breath, and joint pain.
