The frequency of post-COVID-19 condition and its clinical relevance after COVID-19 disease of employees in facilities of preschool childcare

• Evaluate the persisting, impairing symptoms after COVID-19 disease of employees in preschool childcare. • Assess the impairment of general wellbeing after COVID-19 disease and in cases of Post-COVID 19 condition. • Discuss the discrepancy between meeting the WHO criteria for a Post-COVID-19 condition and not meaning automatically a clinical relevance. Evaluation of the rate and symptoms of Post-COVID-19 condition in employees in childcare. A structured questionnaire collected data from two distinct collectives: Collective 1 (C1) consisted of a prospective cohort of 44 employees after COVID-19 disease, whereas Collective 2 (C2) included 222 employees who were retrospectively interviewed. The questionnaire mainly focused on symptoms and wellbeing during or after COVID-19. The main symptoms of Post-COVID-19 condition were impairment of focus, fatigue/exhaustion, reduced stamina, headache and dyspnoea. 30% of the employees in C1 and 7.6% of C2 suffered from a clinically relevant Post-COVID-19 condition with impairment of the general wellbeing. According to the WHO definition, a Post-COVID-19 condition was found in 56.6% (C1) and 25.5% (C2). A Post-COVID-19 condition was a common finding in both our collectives but did not automatically cause an impairment of general wellbeing.
