Self-examination methods for new coronary pneumonia include determining whether there is a history of epidemiological exposure, the severity of clinical symptoms, and whether there is a significant change in clinical symptoms. Self-examination methods are as follows: 1. Epidemiological contact history: to be ranked by epidemiological contact history, if there is no epidemiological contact history, consider the common cold is more likely, if there is a history of epidemiological contact, do not exclude the new crown pneumonia; 2. Clinical symptoms: if the patient’s clinical symptoms are mild, and the disease has not progressed significantly, consider the common cold is more likely. However, if the patient’s symptoms are more severe and there is a significant aggravation in a short period of time, consider the possibility of new crown pneumonia.
