COVID-19 (from the English COronaVIrus Disease 2019), previously coronavirus infection 2019- is a potentially severe acute respiratory infection caused by the SARS-CoV-2 coronavirus. It is a dangerous disease that can occur both in the form of an acute respiratory viral infection of a mild course and in a severe form, specific complications of which may include viral pneumonia, which entails acute respiratory distress syndrome or respiratory failure with a risk of death.
