There is no obvious difference between the fever of new crown pneumonia and the common cold only on the fever itself, both can be manifested as low or high fever, but there are some differences in the other accompanying symptoms of the two. 1. Whether the fever is caused by the common cold or by the new crown pneumonia, it will show the symptom of elevated body temperature. New coronary pneumonia is characterized by low to moderate fever in mild cases, and common cold viral infection is characterized by low to moderate fever; new coronary viral infection can be characterized by high fever in severe cases, and common cold secondary to bacterial infection can also be characterized by high fever. 2. In addition to fever, common cold is usually accompanied by cough, nasal congestion, sneezing and other symptoms; generally speaking, in addition to fever, the new crown pneumonia will also appear to fatigue, dry cough as the main symptoms, and some patients may have a sense of taste, smell or loss. The diagnosis of C. neoformans pneumonia is based on the appropriate clinical epidemiologic history and nucleic acid test results, and it is not recommended to differentiate C. neoformans infection from the common cold by the characterization of fever. In case of fever, if there is relevant epidemiological history, nucleic acid test should be carried out in time, and after the nucleic acid result confirms the diagnosis, it should be reported in time according to the local policy, and isolation and treatment should be carried out; for the fever of the common cold, drinking more water, resting more, and symptomatic treatment can be carried out.
