Defining and measuring long COVID fatigue: a scoping review.

Objective: Long COVID encompasses a range of symptoms in which fatigue is one of the most prevalents. It is clear from other conditions that the definition and measurement of fatigue can be complex, but it is not clear how fatigue is defined and measured in long COVID. To advance our understanding, this review summarises the definitions and measures of long COVID fatigue being used by researchers.

Definitions and measures of long COVID fatigue in adults: a scoping review protocol.

Objective: The aim of this scoping review is to investigate how fatigue is defined and measured in adults with long COVID.

Introduction: Following COVID-19 infection, 10% to 20% of individuals experience persisting symptoms for a minimum of 3 months; this is commonly known as long COVID. Fatigue is one of the most prevalent symptoms of long COVID, but there is currently no consistently applied definition of long COVID fatigue.
