What should people who don't wear masks in public do?

I think if you meet someone who doesn't wear a mask in public, you can kindly tell him to wear a mask to avoid secondary infection. Even if you are healthy now, you can easily infect others' diseases without wearing a mask. For the sake of health, please wear a mask. We can be kind enough to let the other person accept wearing a mask, so that he can be healthy, because everyone wants to be healthy and doesn't want to be infected. only

Generally speaking, the expected gain of not wearing a mask is greater than the expected loss of this behavior. Here are some typical examples: 1. During the epidemic period, even in areas with high epidemic risk level, at the entrances of various public places (such as shopping malls, office buildings and residential quarters), there will still be quarrels or conflicts between intruders and staff who do not wear masks. For intruders who forget to wear or carry masks, observing the rules of wearing masks means that they need to get a mask first: they either spend money on masks or spend time and kindness asking people around them to send them. But in most cases, insisting on breaking in without a mask does not require the consumption of money, time or human feelings. Without the protection of compulsory force, it is difficult for staff to persuade, stop or even warn intruders, resulting in substantial losses. Even if a typical "Australian runner" is punished, on the whole, similar punishment only affects a very small number of unruly people. It is more profitable to insist on breaking in without a mask than to benefit. However, when inspectors become compulsory groups such as police and soldiers, the behavior of intruders who are still "head iron" storms will be significantly reduced. When power is forced to intervene, interests are reversed. Forced entry is not only unprofitable, but even severely punished. 2. Preventive medicine believes that for a certain type of infectious disease, if the proportion of people vaccinated reaches a certain value, even those who are not vaccinated will hardly be infected again. Take measles as an example, this value is considered to be 92%~95%. Similarly, if the vast majority of people wear masks, even if a few people don't wear masks, it is difficult to spread the COVID-19 epidemic in a large scale, because the probability of COVID-19 in the environment is very low. The advantages of not wearing a mask at this time include more comfortable face and smoother breathing, but the risk is very low. However, this kind of behavior has the risk of damaging the public interest and is not worth promoting. Each of us should wear a mask when we go out.
