The study will follow COVID-19 patients who required intensive care at Uppsala University Hospital and were included in the Uppsala COVID-19 biobank. The patients will be contacted after three to six months for a first follow-up with assessment of functional level in activities of daily life, psychiatric symptoms, neurological symptoms and working capacity as well as specific organ functions. The organ functions will include circulation, respiration, coagulation, immune function and kidney function. In addition, blood and urine will be collected for biobanking.
