Novel pneumonia cannot be fully judged by a tickling throat and coughing sputum alone. Novel pneumonia usually has a history of epidemiologic exposure, recent exposure to suspected or confirmed patients, and symptoms such as fever, malaise, cough, sputum, sore throat, and sometimes even gastrointestinal symptoms such as nausea and vomiting. In severe cases, dyspnea and impaired consciousness may occur. Lung CT usually shows interstitial changes, and blood tests often show normal or below-normal white blood cells, below-normal lymphocytes, and C-reactive protein and calcitoninogen can be negative. The diagnosis of novel pneumonia can be confirmed clinically by two consecutive positive nucleic acid tests, so the diagnosis of novel pneumonia cannot be confirmed clinically simply by itchy throat and coughing sputum.
