Inclusion criteria

For Sites in Austria: Inclusion Criteria: For the +COVID-19 group: * Confirmed COVID-19 positive test result OR extremely high likelihood of COVID-19 infection (e.g., family member or other person co-habiting with subject with a documented infection; passenger from cruise ship with +COVID- 19) * Hospitalisation for severe COVID-19 infection until 01.06.2020 * COVID-19 patients having required oxygen therapy as per local guidelines (including those requiring a ventilator, central venous catheter or ECMO) For the control group: * Hospitalisation for any disease other than COVID-19 infection until end 2019 (31.12.2019) * Patients having required oxygen therapy as per local guidelines (including those requiring a ventilator, central venous catheter or ECMO)

Exclusion criteria

* Known hypersensitivity or allergic reaction to ATIII * Participation in any interventional trial during the time of individual observational period (date of hospitalisation to the date of removal of oxygen therapy or death, whichever occurred first) * Pregnant women For Sites in France: Inclusion Criteria: For the +COVID-19 group: * Confirmed COVID-19 positive test result OR extremely high likelihood of COVID-19 infection (e.g., family member or other person co-habiting with subject with a documented infection; passenger from cruise ship with +COVID-19) * Hospitalisation for severe COVID-19 infection and discharged from the hospital or died before start of documentation. COVID-19 patients having required oxygen therapy as per local guidelines (including those requiring a ventilator, central venous catheter or ECMO) For the control group: * Hospitalisation for any disease other than COVID-19 infection until end 2019 (31.12.2019) * Patients having required oxygen therapy as per local guidelines (including those requiring a ventilator, central venous catheter or ECMO)
