Supportive treatment: Supportive treatment like oxygen therapy via mask is used if patients develop shortness of breath and hypoxemia. In the case of resistant hypoxemia, Extracorporeal membrane oxygenation (ECMO) is used. Patients with severe respiratory Distress may need ventilator support. Corticosteroids may be used as a supportive therapy, but its use and efficacy are controversial as they may make patients more prone to infections [9].
