It is a systemic disease caused by influenza virus infection that mainly involves the upper respiratory tract. It is a highly contagious and fast-spreading disease.
2.What is the transmission route of influenza?
It is mainly spread through droplets in the air, person-to-person contact or contact with contaminated objects. Influenza virus can be divided into A (A), B (B), C (C) three types, A virus often occur antigenic mutation, infectious, rapid spread, very easy to occur in a wide range of epidemics.
3.What kind of performance will there be when I get influenza?

①Blood count.
Total white blood cell count is usually not high or reduced, and lymphocytes are increased. Lymphocytes may also be elevated in severe cases. If combined with bacterial infection, the total white blood cell count and neutrophils will rise.
②Blood biochemical examination.
In some cases, hypokalemia is observed. In a few cases, creatine kinase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, creatinine, etc. are elevated.
(iii) Pathogenesis-related tests.
Antigen and nucleic acid testing of viruses can be used for early diagnosis; antibody testing can be used for retrospective investigation.
④Imaging examinations.
Some patients performing chest X-ray or CT examination can show signs of bronchial infection with increased bronchial texture, and severe patients can have infiltrative lung lesions or pleural effusion, or even fusion into a sheet.

Influenza vaccination has been recognized by the international medical community as the most effective weapon to prevent influenza. Since influenza viruses mutate rapidly, usually the type of epidemic varies from year to year, and the epidemic strains of influenza viruses are mutating every year. Therefore, annual vaccination with the latest influenza vaccine is the only way to achieve preventive effect. Preventive measures also include exercising and strengthening your body. During the flu season, windows should be opened frequently, and elderly people and children should visit crowded places as little as possible.
