What reason does flu have thick phlegm the 5th day

First: the main way of influenza is through infection. This kind of infection is generally caused by contacting animals and plants. Because animals and plants are particularly easy to infect each other, they should try not to be too close to each other when they contact each other. They should keep a distance, especially those who are allergic to plants.

Second: the spread of influenza virus. The spread of influenza is very fast, especially in the air. Therefore, in places where there are many people, people talk with each other, and saliva will be ejected unconsciously, or the exhaled gas will be spread out. Once they come into contact, they will be infected.

Third: influenza often occurs in people who have no immunity. Because their constitution is relatively weak, once there is a virus, they will first choose to invade the body of this kind of people. Therefore, influenza has occurred, and this kind of people are infected for the first time. In addition, people suffering from other diseases are in a morbid state, and naturally can not escape.
