The first symptom of pneumonia in novel coronaviruses is currently fever. In order of its frequency of occurrence, its symptoms are fever, dry cough, and malaise. That is, fever is the most frequent symptom, dry cough is the second most frequent symptom, followed by malaise. The occurrence of dyspnea, etc. after the incubation period is also an important sign for diagnosis. Many conditions can cause a person to have a dry cough, including tasting irritating substances or allergen attack. If only a dry cough is present, the diagnosis of novel pneumonia needs to be determined in conjunction with symptoms such as the presence of persistent high fever, malaise, history of exposure, or subsequent dyspnea. A dry cough alone cannot be considered novel coronavirus pneumonia. Content source: Dr. Yurai
