In addition, performing microbiological testing to determine the type of virus causing disease is essential.

Treatments

Treatment against respiratory failure by clearing airways, clearing sputum, drooling in the throat, trachea of ​​the patient, intubation, giving oxygen, flapping the chest, letting patients cough, sputum out. Anti-shock treatment by adjusting electrolyte and water disorders to ensure a 70-80% volume of physiological needs, use of infusion solutions: 5% lactate, 5% glucose , 0.9% natricloride .
