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Preprints are preliminary research reports that have not been certified by peer review.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
Background Controlled population-based studies on long-term health sequelae of SARS-CoV-2 can help to identify clinical signs specific to Long COVID and to evaluate this emerging public health challenge. Aim To examine prevalence differences of Long COVID-associated symptoms among adults with and without SARS-CoV-2 infection in Germany. Methods This population-based, retrospective study (11/2021-2/2022) included 7,683 working aged adults (18-65 years), a subset of the Corona Monitoring Nationwide study in Germany. Prior SARS-CoV-2 infection was defined based on self-reported PCR-confirmed infections and IgG-antibody dried blood spot testing. Participants answered a questionnaire including 19 common symptoms of Long COVID experienced in the six months preceding the survey. We estimated population-weighted prevalence of (1) individual symptoms, and (2) [≥]1 symptom, with and without impact on work ability, by infection status within strata of sex, age group, income and comorbidity. We calculated model-adjusted prevalence differences and the probability that symptoms among infected are attributable to infection. Results 12 of 19 symptoms showed a significantly higher prevalence in infected than non-infected participants, including fatigue (27.5% versus 18.3%; p<0.001), concentration problems (22.2% vs. 13.1%; p<0.001), shortness of breath (15.6% vs. 7.5%; p<0.001), and smell and taste disorder (10% vs. 1.2%; p<0.001). [≥]1 symptom with impact on work ability was more prevalent following infection (16.0% vs. 12.2%; p=0.06) with a model-adjusted prevalence difference of 3.8% (95%-CI -0.5-8.0). Conclusion We observed a rather small excess prevalence attributable to SARS-CoV-2 infection. However, the absolute number of persons places great demands on the health care system and may affect economic productivity.
