The National Academies of Sciences, Engineering, and Medicineopens in a new tab or window has just proposed a new case definitionopens in a new tab or window for long COVID. The criteria specify that the condition “is present for at least 3 months as a continuous, relapsing and remitting, or progressive disease state” and the condition can be defined by “single or multiple symptoms” that “can range from mild to severe.” We are also informed that there are “more than 200” possible symptoms. Finally, although “some individuals with long COVID are severely affected,” there are no specific limitations in functioning.
