The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in December 2019 and was declared a pandemic in March 2020 by the World Health Organization (WHO) [1]. Clinical manifestations of COVID-19 range widely [2]. Even though most patients experience mild to moderate symptoms, a fair number of them suffer from severe pneumonia, acute respiratory distress syndrome (ARDS) and multiorgan dysfunction, with increased mortality [2]. The global vaccination has shown its effect, nevertheless, the incidence of COVID-19 hospitalizations and deaths is rapidly increasing over the last few months [1].
