Notes: *Other conditions include; Heart, Lung and Renal Disease and Malignancy. **Asymptomatic; Grade A, are patients with no signs or symptoms of infection; Mild; grade B include Patients with upper respiratory tract infection symptoms and other mild symptoms such as fever and gastrointestinal symptoms without evidence of pneumonia. In KFSHRC guidelines, we have an additional category, which is the Moderate cases: grade C, patients with hypoxia, with oxygen saturation less than 93% at rest or presence of pneumonia. The Severe disease; grade D refers to dyspnea, respiratory rate ≥30/ min, blood oxygen saturation ≤93%, partial pressure of arterial oxygen to fraction of inspired oxygen ratio <300, or lung infiltrates >50% within 24 to 48 hours.
