New coronavirus is more infectious and less lethal than SARS, so there is no need for excessive public fear. Generally, infection with neocoronavirus pneumonia can be completely cured if treated promptly in 2-3 weeks. Patients with mild infection may be asymptomatic in the early stages, usually with upper respiratory symptoms in the first week, namely fever, cough, malaise, and in some cases, nasal congestion, headache or sore throat. The inflammatory stage of the lungs can be reached around 7 days after the onset of the disease, and the patient may have difficulty breathing and chest suffocation. In case of underlying disease, respiratory failure or uncorrectable acidosis, or even respiratory distress, septic shock, and hemolytic coagulation disorders may occur. However, most patients do not progress to the severe or critical stage. Normal individuals are completely cured 2-3 weeks after infection. If lung function is poor and the infection is severe, residual symptoms of pulmonary fibrosis may develop. However, with aggressive treatment most of them should be completely absorbed and there is no need to worry excessively. Content source: Dr. You Lai
