COVID-19 can be spread by aerosol, which environmental aerosol is more risky?

For densely populated places with high air pollution, the risk of aerosol infection may be higher. For the new type of coronary pneumonia, we know that aerosol transmission is another route of transmission today, which undoubtedly makes us understand the fighting place of this virus. We now know where and how the enemy fought, which is of great help to our victory.

When we say aerosol, we may feel more abstract. It can be said that it is relatively small, flexible, can fly and float, and the virus adheres to it and spreads in the air. Aerosol is suspended in the air after fog drops become droplet nuclei, and its vitality is more tenacious, so it spreads with the flow of air. But the probability of bacteria staying in aerosol is not very high. Usually, we can effectively avoid it by taking protective measures and paying attention to our own behavior.

On the one hand, it is one of the main reasons to prevent new coronary pneumonia, enhance physical fitness, improve immunity and avoid contact with infectious sources. The so-called source of infection is everything that may carry the virus, including humans. Therefore, the state calls on us not to go out as much as possible when it is unnecessary. Even if we go out, we should take protective measures and wear masks.

For people who go out, try to avoid going to crowded places with poor air circulation. This environment is the place where viruses are most likely to exist, and normal patients may inhale aerosols with viruses when breathing. This is the most terrible. So, for your own safety, go to a crowded place if you have nothing to do. Even if you go out, don't go to crowded places and keep a certain distance from people. Because the virus concentration decreases with distance.

No matter what kind of environment aerosol spreads in, distance is its prevention and control measures. After its concentration is reduced at a certain distance, the dose of human infection is also low, and the natural danger is also low. I believe that we will soon overcome this epidemic. Come on, China, and Wuhan!
