The severity of coronavirus disease 2019 (COVID-19) ranges from asymptomatic infection to severe illness requiring mechanical ventilation. Immunological factors which lead to severe disease in certain COVID-19 patients remain incompletely understood. Neurological damage and complement activation may be a consequence of excess inflammation in severe COVID-19. The investigators plan to study the innate and adaptive immune response and potentially associated complications such as neurological damage and complement activation in mild, moderate and severe COVID-19 courses.
The Investigators plan to study the innate and adaptive immune response, the inflammatory response, and associated complications such as complement activation and neurological damage in SARS-Cov-2 infected individuals. Patients with mild, moderate and severe COVID-19 disease will be enrolled.
