Early symptoms of New Coronary Pneumonia may manifest as a sore throat, but this symptom is not specific and the presence or absence of New Coronary Pneumonia cannot be determined clinically based on this one symptom. Patients with Neoplastic pneumonia may also have early upper respiratory reactions such as fever and dry cough, as well as eye changes, taste and smell changes, gastrointestinal reactions, neurological changes, and skin changes, but some people may also be asymptomatic after the disease. If you suspect a new coronavirus infection, you should seek prompt medical attention, which usually requires a scientific and systematic examination. Nucleic acid testing is performed, and for accuracy, CT lung examinations, blood sampling for laboratory tests, etc., are also available, and usually early lung changes are not obvious. However, the total number of peripheral blood leukocytes in patients early in the course of the disease can be normal or decreased, and a decrease in lymphocyte count is also seen. Some patients may also have increased liver enzymes, lactate dehydrogenase, C-reactive protein, and other indicators. If it is clear that the disease is neo-colonial pneumonia, it needs to be treated in isolation. Usually, you need to pay attention to good protection, ensure personal hygiene, wear masks and wash hands regularly to prevent infection. In addition, the disease can be prevented by vaccination.
