Case 270

 This week, we listed 5 cases who got COVID-19 and died for previous two months (2022 01 01 to 2022 02 28) to investigate what are the risk factors for poor prognosis. Patient personal information (Table 1), present illness (Table 2) and laboratory test (Table 3) are presented. The items of the laboratory test were chosen from poor prognosis factors previously reported. Chest radiographs or chest CT are shown in Figs 1-5.
