Development of a definition of Long COVID

Researchers identified 37 symptoms across multiple pathophysiological domains that are more common in SARS-CoV-2 infected participants at six months post-infection. A preliminary rule for identifying postacute sequelae of SARS-CoV-2 infection (Long COVID) was derived from a composite symptom score and requires further refinement.
