Prevalence of severe fatigue after SARS-CoV-2 infection in Norway: a prospective 2-year follow-up study

In this cohort, severe fatigue was common, greatly impacted quality of life and persisted for up to 2 years following SARS-CoV-2 infection. Fatigue severity was associated with symptom burden in the acute phase but not with antibody levels or other demographic variables. These findings underscore the need for long-term follow-up and support for affected individuals.
