Cough can be present in a variety of respiratory illnesses, and patients with novel coronavirus infections can have coughing symptoms, but coughing does not necessarily mean that they have a novel coronavirus infection. Patients with novel coronavirus infection can have coughing symptoms throughout, but in addition to coughing, they may have other respiratory symptoms such as fever, sore throat, sneezing, and runny nose. After a week, symptoms of pneumonia such as cough, fever, dyspnea, progressive respiratory acidosis that is difficult to correct, and even septic shock and coagulation disorders will develop. Mainly there will be a positive nucleic acid test of novel coronavirus, and after a week there will be a manifestation of inflammatory infection in the lungs, and chest CT may show patchy shadow, infiltration shadow, and in severe cases, solid change. So cough can be a symptom throughout in patients with novel coronavirus infections, but cough is not always a symptom in patients with novel coronavirus pneumonia. Content source: Dr. Yurai
