Brief Summary

The ongoing corona virus disease 2019 (COVID-19) is a viral acute respiratory tract infection caused by server acute respiratory syndrom coronavirus typ 2 (SARS-CoV-2). The signs and symptom of SARS-CoV-2 infection vary and most people with COVID-19 experience illness of mild or moderate severity and recover with symptomatic treatment outside of hospital. Studies have found that some people experience lingering/long-lasting symptoms and only a minority of patients were completely free from COVID-19 related symptoms after two months. About one third still had up to two residual symptoms and 55% had three or more. As far as we know no study on lingering symptoms has been published in patients after a mild or moderate infection managed in primary care settings. The aim of this study is to explore the course of disease over a one year period and describe lingering symptoms and their impact on well-being and daily activities in adult non-hospitalized patients with previous established COVID-19 infection.
