This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
A subset of patients has long-lasting symptoms after mild to moderate COVID-19. In a prospective observational cohort study we analysed clinical and laboratory parameters in 42 patients (29 female/13 male, median age 36.5 years) with persistent moderate to severe fatigue and exertion intolerance six months following COVID-19 referred to as Chronic COVID-19 Syndrome (CCS). Most patients were moderately to severely impaired in daily live. 19 patients fulfilled the 2003 Canadian Consensus Criteria for myalgic encephalomyelitis/chronic fatigue syndrome referred to as CFS/CCS. Hand grip strength (HGS) was diminished in most patients. Association of several biomarker with key symptoms of physical and mental fatigue and post exertional malaise indicate low level inflammation and hypoperfusion as potential pathomechanisms.
