Transmission, start of symptom and morbidity among Danish COVID-19 patients admitted to hospital.

CONCLUSIONS: The frequency of co-morbidity in hospital-admitted COVID-19 patients and the correlation to death and ICU attendance were analysed. In all, 74% of the infection cases were of unknown source during the first weeks of the epidemic, which points to considerable community transmission and possibly pre- or asymptomatic transmission, also several weeks before 21 February 2020. FUNDING: none. TRIAL REGISTRATION: not relevant after correspondence with the Ethics Committee of Region Zealand. Furthermore, permission was granted from The Danish Data Protection Agency, Region Zealand (REG-070-2020). PMID: 32800066 [PubMed - in process]
