Abstract
The prevalence of post-COVID syndrome (PCS) has not yet been conclusively clarified. The existing definitions primarily reflect temporal aspects, but disregard functional deficits as well as the objectification of symptoms. This leads to diagnostic as well as therapeutic ambiguities. Pubmed was searched for systematic reviews dealing with the impact of SARS-CoV-2 infection. The underlying definitions as well as temporal inclusion criteria were extracted. 16 systematic reviews were included, 11 of which included a definition of PCS. In 58 % of the individual studies analyzed, patients with symptomatology > 12 weeks and thus according to the definition of PCS were included. CONCLUSION:: Further clarification of the definition of PCS is necessary to facilitate diagnosis and multimodal treatment and to use the scarce therapeutic resources accordingly.
