Novel coronavirus pneumonia can be clinically fatal, mainly because of the rapid progression of the disease, with significant symptoms of acute respiratory distress syndrome, shock, acidosis, and coagulation disorders. In particular, it induces respiratory failure, decreased cardiac function, the need for ventilators, decubitus ulcers and severe intrapulmonary infections, and related complications. The mortality rate for neoconjunctivitis is high because there are no obvious drugs to treat its viral infection, like interferon, ritonavir, ribavirin, and traditional Chinese medicine such as sputum fever clear and xiyanping can control its symptoms, but there is no absolute certainty for the killing of the virus, and the clinical treatment is still based on symptomatic treatment. The cause of clinical death has a lot to do with the patient’s weak immunity.
