It's autumn soon. One thing you need to prepare for the fall is the flu vaccination. With prevention, you can have a healthy autumn and winter.


One that many people tend to confuse is "The flu is a bad cold.". But the flu and the common cold are two very different things. 


About 200 different cold viruses cause the common cold regardless of the season. However, there are four types of influenza viruses, A, B, C, and D, of which A and B cause influenza in humans. 


It is prevalent from autumn to winter every year, and the number of patients increases rapidly. After an incubation period of 1~2 days, symptoms appear. The main symptoms include high fever, headache, muscle pain, general weakness, etc., accompanied by respiratory diseases such as cough, sore throat, and runny nose. Healthy adults recover after a few days, but in the elderly, children, pregnant women, and chronically ill or immunocompromised people, it can lead to severe complications such as pneumonia, heart failure, meningitis, etc., leading to death.

In particular, people over the age of 65 who have pre-existing chronic diseases such as lung disease, diabetes, and chronic kidney failure should be more careful because the flu can exacerbate their symptoms, and the hospitalization rate for flu complications is more than four times higher than that of the elderly.


To prevent this flu, getting vaccinated before the annual epidemic is recommended. It takes about two weeks for immunity to develop, so it is recommended to vaccinate in September ~ November. In healthy young people, it is so effective that it can be prevented by up to 90%. For the elderly and chronically ill, vaccination is also recommended because it is somewhat less effective in reducing the incidence of complications.


In addition, to prevent it in life, taking care of your physical fitness and immunity daily is necessary. You should wash your hands frequently and after going out, and avoid touching your eyes, nose, mouth, etc. During flu season, wearing a mask in crowded places is a good idea.
