Coronavirus infection (COVID-19) – determined on the basis of identification of polymerase chain reaction analysis of samples taken from the nasopharynx and nose, proceeds in three clinical forms with the same positive result: first form is acute respiratory viral infection with mild inflammatory symptoms of the upper respiratory tract, second form is acute pneumonia, which is not dangerous for life and third one is severe pneumonia with acute respiratory distress syndrome. In-depth study and analysis of available scientific data on the course of clinical asymptomatic subclinical form of coronavirus infection (COVID-19) will not only ease the burden on the health system, but also eliminate unnecessary panic among the population and, subsequently, lead to economic stability.
