I just went out shopping and was tired after shopping, so I sat in the rest area of the mall for a while. Maybe it's because there are many people in the shopping mall during the Spring Festival, but no one wears a mask ... On the contrary, my partner and I and several young people are sitting there wearing masks, which is like an alternative. There is no way. Maybe we are afraid of death.

When I got home, I just saw the affection of a young man, and I couldn't help but leave tears of approval:

"The peers who are dying at ordinary times should be the main force to buy masks these two days, and even dare not go to the movies. Usually thieves like to forward earth-shattering health articles such as eating mala Tang will cause cancer and not eating garlic. I repeatedly told them not to go out to crowded places, remember to wear masks and reply to us: nothing! "

"My parents believe in Banlangen and smoked vinegar, and even believe that putting sesame oil on the nose and chanting great compassion can resist epidemics. I believe in so many strange things, but I don't believe in masks, and I still say what masks to bring. Life and death are doomed. Don't let some businesses make money ... "

Why do experts advise everyone to wear masks, wash their hands frequently and not go to crowded places? In fact, if the virus wants to "infect" successfully, it must have three elements: the source of infection, the route of transmission and the susceptibility of the population. Otherwise it won't be contagious. This is a virus threat, so I mainly talk about the most critical source of infection and transmission route.

Source of infection: Virus infection mainly depends on two kinds of people, one is people who have started to have fever, cough and other symptoms and have been infected. There is another person who looks "healthy" and has no symptoms.

Patients who are already sick are highly contagious and are the main source of infection, while "invisible infected people" in the incubation period are also highly contagious because they are not easy to be found. But if you are a healthy person without disease, even if you carry the virus, the spread is very small.

Transmission route: mainly through the form of droplets, such as spitting when talking, coughing with droplets, the patient's runny nose, and even the patient's normal panting, some viruses may be brought out. Moreover, after these bubbles dry, these viruses can still float in the air, ready to invade.

And those infected friends who have a fever and cough will have more viruses in their bodies when they cough. This picture is still drawn too little. How can there be thousands or even hundreds of millions of viruses hidden in this cough droplet? If there are 10 people coughing back and forth in a room, how many viruses do you have? It was really scary. Moreover, according to the incidence of this disease, the new pneumonia virus is particularly aggressive to the human body. Once the virus is inhaled, the incidence rate is very high. Therefore, once again, it is absolutely necessary for everyone to wear masks during this epidemic!

What's the use of washing hands often? This thing seems useless. In fact, this little trick is very important to prevent infection!

Why? Our hands often come into contact with tables, chairs, benches and other miscellaneous things. For example, when we go to a public place, we may have to grab the handrail to open the door. Who knows who touched the handle last? Is this person a patient? Have you ever touched a doorknob or elevator with a hand that wiped your nose, covered your mouth or was infected with a virus?

After we stay in densely populated areas, it is inevitable that we will have a little virus on our hands. If we happen to feel itchy nose or eyes, rub it with our hands, or eat the virus directly in our mouth when eating, we will open the door and welcome the terrible virus to "sneak" into our bodies. If a family has an "infected person", all family members may be infected!

Under what circumstances must I wear a mask? Wash your hands? Wear a mask: you may come into contact with patients when you take the bus and subway. Also, if you go to a hospital or a place where there may be patients around you, you must wear a mask consciously to avoid infecting others. So schools, hospitals, stations and other densely populated places are very dangerous.

Wash your hands frequently: In addition to washing your hands before eating, you must wash your hands with tap water, hand sanitizer or soap after going out to work, shopping or coming back from the hospital. Imagine the virus sticking to your hands. It's really scary.

Finally, I want to say a few words to you: If you have a fever and cough, please wear a mask consciously, not only for the health of others in public, but also for the safety of your loved ones.

If you don't have a fever, cough and infection, you are in good health. When you go out, you must also take protective measures. Don't think that you can resist the invasion of "novel coronavirus" just because you have good immunity, so you have great confidence in streaking.
