The difference between common fever and new pneumonia includes the following aspects: 1. Common fever is mostly seen in respiratory infectious diseases with nasal congestion, runny nose, sneezing, sore throat, congested and swollen tonsils, even with pus spot formation, and also includes fever caused by common pneumonia. This fever, if it is a viral infection, is given antiviral and herbal treatment, and the body temperature mostly returns to normal in 3-5 days. If the fever is caused by bacterial infection, the blood count can indicate an increase in total white blood cells and neutrophils, and calcitoninogen and C-reactive protein can also be increased, and if accompanied by pneumonia, the chest CT can indicate changes in pneumonia. The diagnosis of novel coronavirus pneumonia can be further confirmed by a positive nucleic acid test. Fever is not the main symptom of novel coronavirus pneumonia, so a combination of antiviral therapy and immunomodulatory therapy is needed for treatment.
