Coughing at night but not during the day may be considered novel coronaviral pneumonia caused by a novel coronavirus infection. In addition to cough, patients with novel coronavirus pneumonia may also have fever, dyspnea, and other respiratory symptoms, and as the disease progresses, patients may develop hypoxia, shortness of breath, or even respiratory failure. In addition, common bacteria or viruses, as well as pathogenic microorganisms such as mycoplasma and chlamydia, can also invade the body and cause respiratory symptoms such as coughing at night and not during the day. To determine whether there is a novel coronavirus infection, the patient’s viral nucleic acid can be tested to clarify whether it is a novel coronavirus infection.
