How to prevent influenza and keep these three colds away from you

Four seas network: these days cool down, the flu season has arrived, a lot of friends around have been recruited. Although the cold is small, it's also very hard to get a cold, which affects work and life.

In fact, cold is a very general concept. If the nose and throat are uncomfortable, broadly speaking, it can be called cold. But it's too vague to say that, it covers almost all the diseases of the upper respiratory tract. Therefore, we should first standardize the cold mentioned in this answer. The cold here refers to the disease caused by virus reproduction on the nasal mucosa, so the treatment of cold depends on what virus is infected on the nasal mucosa. Basically, it can be divided into two categories: the common cold and the influenza.

How to divide it?

As long as it is not caused by influenza virus, it is regarded as common cold. As you can see from the name, the symptoms of cold caused by other viruses are not as serious as influenza, so there is no subdivision. In fact, there are hundreds of viruses that can cause the common cold, and the influenza virus is a kind of positive sticky virus with a specific structure, and the symptoms it causes are relatively serious, so it is necessary to carry it out alone, and also carry it out alone for prevention and control.

Three ways to prevent cold

Let's start with the common cold. The common cold is usually infected several times a year or several times a month. Most of it is caused by rubbing your eyes and picking your nose. There is a lacrimal duct in the eye, which is connected with the nose, so when you rub the eyes, the virus will infect the nasal mucosa along the lacrimal duct. To pick the nose is needless to say. It is equivalent to putting the virus on the nose mucosa directly. How can there be viruses on your hands? In fact, there are a lot of viruses on the surface of many objects. When the viruses stay on those things, they are similar to dust. There is no sign of life. Only when they come to the mucous membrane, they start to wake up.

The first prevention of cold: don't touch your eyes and nose. As long as it's public appliances, such as door handle, faucet, glass, mouse, mobile screen, there are viruses on them. According to the statistics of special people, the probability of falling the virus that may cause common cold on daily articles is close to 50%. These viruses can stay on your hands for an average of 2 hours. At this time, if you rub your eyes and pick your nose, you will almost have common cold.

The second prevention of cold: wash your hands frequently. Especially when you come back from public places, if you really want to pick your nose, you should wash your hands first. The U.S. Army once made statistics on common cold among recruits. They divided them into two groups. One group strictly required them to wash their hands, and the other group didn't do anything. If some of them had a good sense of hygiene, they would wash their hands carefully. By contrast, the group that ordered strict hand washing had half as many common colds as the group that did not. So, we can basically come to the conclusion that as long as we wash our hands carefully, the number of colds in a year can be halved. Maybe you don't think the number of times you reduce is too much. At most, you can reduce the number of colds twice. But you think it's comfortable for half a month.

The third prevention of cold: wear masks. In this way, it can avoid directly inhaling the patient's droplets, especially in the particularly crowded space. For example, there are hundreds of people in the subway car. According to the probability, at least one or two of them should have a cold. If they sneeze, others will suffer. So wearing a mask is not only a requirement for healthy people. If you have a cold, you should think more about others. Please wear your own mask.
