RT-PCR test positive for SARS-CoV-2 criteria for patients with moderate symptoms:evidence of lower respiratory disease( dyspnea, Chest compression و..) oxygen saturation (SpO2) between 90 to 93% lung infiltrates<50% criteria for patients with sever symptoms: Dyspnea respiratory frequency >30 breaths/min oxygen saturation (SpO2) < 90% and PaO2/FiO2 <300 mm Hg lung infiltrates >50%
