“…For community-acquired pneumonia (CAP), several prognostic scoring systems have been developed and studied since 1982, including the British Thoracic Society rule ( Anon, 1987 ), the modified British Thoracic Society rule ( Neill et al, 1996 ), the Pneumonia Severity Index ( Fine et al, 1997 ), and the CURB-65 score ( Lim et al, 2003 ), among others. Recently, the performance of these existing CAP severity scores has been tested in patients with COVID-19 ( Nguyen et al, 2020 , Satici et al, 2020 , Fan et al, 2020 ). Nevertheless, COVID-19 has proved to be more than just pneumonia, and its clinical spectrum varies from asymptomatic forms to systemic manifestations in terms of sepsis, septic shock, and multiple organ dysfunction syndromes, and affecting countries, races, and ages in different, and sometimes unpredictable, manners ( Cascella et al, 2020 , Wiersinga et al, 2020 ).…”
