BACKGROUND: Although persistent symptoms after Coronavirus disease 2019 (COVID-19) are emerging as a major complication to the infection, data on the diversity and duration of symptoms are needed. METHODS: Patients aged ≥18 years with a positive polymerase chain reaction (PCR) test for severe acute respiratory syndrome coronavirus 2 and hospitalized at the Department of Infectious Diseases, Aarhus University Hospital, Denmark, in the period March 11th to May 15th, were offered follow up after hospitalization. On admission, comprehensive symptom and medical history were collected, including demographic characteristics, duration of symptoms, comorbidities and concomitant medication. At discharge, patients were offered follow-up consultations – either by telephone or in-person visit – at 6 and 12 weeks at our Post-COVID-19 outpatient clinic to assess whether symptoms present at admission had resolved. RESULTS: During the inclusion period, 71 patients were admitted with COVID-19. Of these, 10 patients died, 3 were transferred to another region, 4 declined to participate and 5 were lost to follow-up before 12 weeks evaluation. Thus, 49 patients were included. Overall, 96% reported one or more persisting symptoms at 12 weeks follow-up. Main symptoms were fatigue, dyspnea, cough, chemosensory dysfunction, and headache. CONCLUSION: A wide range of persistent symptoms in patients recovering from COVID-19 were present 12 weeks after hospitalization calling for larger descriptive studies and interdisciplinary research collaborations.
