The prognosis of most patients with novel coronavirus pneumonia is good and relatively well treated, based on the cases admitted. A few patients are in critical condition, such as respiratory distress accompanied by hypoxemia after one week of onset, and in severe cases, rapid progression to acute respiratory distress syndrome, septic shock and uncorrectable metabolic acidosis, as well as bleeding and coagulation dysfunction, which can cause respiratory and circulatory failure. The condition is more critical at this time, and the prognosis is worse especially in the elderly and in patients with chronic underlying diseases. In addition, children’s cases also have relatively mild symptoms, which also have a relatively good prognosis and are relatively easy to treat.
