According to the information available, the majority of patients with novel coronavirus pneumonia are of the mild or common type and can be completely cured. Severe cases may require antiviral medication and invasive and noninvasive ventilators and high-flow oxygenation. Most patients can be cured, but only a small number of patients may become critically ill. Critically ill patients may require tracheal intubation, ventilator therapy, or even extracorporeal membrane lung, or ECMO, in particularly severe cases. Once ECMO treatment is performed, the prognosis may be slightly worse. In severe cases, especially critical cases, the prognosis is worse once the ventilator treatment is not effective and reaches the stage of using artificial membrane lung. Thus, in terms of overall statistics, more than 80,000 cases have been diagnosed and more than 3,000 deaths have occurred, with a new coronavirus pneumonia morbidity and mortality rate of about 3-4%. As more patients are cured, the number of confirmed infections is gradually decreasing, as are the number of new cases. Some critical cases may die due to ineffective treatment, resulting in a slight increase in the death rate, but the death rate from novel coronavirus pneumonia is significantly lower than that of SARS in 2003.
