How many days does the novel pneumonia take to develop?
After being infected with the novel coronavirus pneumonia, symptoms generally appear within three to seven days, with the shortest onset reported within one day and the longest at 27 days. However, most patients develop symptoms within two weeks, typically exhibiting respiratory symptoms post-onset. The novel coronavirus primarily attacks the lower respiratory tract, including the trachea, bronchi, and lungs. Patients often experience recurring fever, with temperatures generally ranging between 38 to 39°C, lasting over 72 hours, accompanied by significant coughing. In the early stages, there is usually no noticeable expectoration, presenting as a dry cough. Most patients also experience significant fatigue. If the condition progresses, patients may suffer from shortness of breath and decreased blood oxygen saturation, leading to apparent respiratory distress. In severe cases, patients may experience respiratory failure and even death.
