The difference between neocoronavirus and neocoronitis pneumonia is that neocoronavirus is a pathogen and neocoronitis pneumonia is a disease. Neocoronavirus is the pathogen that causes neocoronavirus pneumonia. After invading the human body through direct transmission, aerosol transmission and contact transmission, and after an incubation period of 1 to 14 days (mostly 3 to 7 days), the infected person shows clinical symptoms, mostly fever, dry cough, malaise as the main manifestations, and some patients may have nasal congestion, runny nose, diarrhea, etc. The main manifestations of the new coronavirus in the infected person are fever, dry cough, malaise, and diarrhea. The primary criterion for confirming the diagnosis of C. neoformans pneumonia is a positive nucleic acid test for C. neoformans virus. Confirmed cases are treated according to the appropriate clinical phenotype. Users are advised to obtain information about the new coronavirus outbreak from regular channels, and not to believe in rumors or spread them. Tip: The terms “new coronavirus pneumonia” and “new coronavirus pneumonia” mentioned in this article were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
