Novel Coronavirus Pneumonia is a very important public health issue that is currently being faced, and most people are very concerned about the severity of Novel Coronavirus Pneumonia infection and whether there is a life-threatening risk. It is important to differentiate between different groups of people who have been infected with novel coronavirus pneumonia, as the severity of the disease varies. Children or young people infected with novel coronavirus pneumonia may have fever, cough, dyspnea and lung manifestations, but most patients will eventually recover. The majority of patients who have progressed to the severe or even critical form of the disease are now elderly patients with comorbidities such as COPD and diabetes, and these people are at greater risk of exacerbations and even life-threatening conditions.
