2019.12--2022.12，被保护两年，被折腾一年，毁誉参半，今终落下帷幕。
感谢医务工作者和基层的工作人员。感谢你们的辛勤付出，让大多数人免于新冠感染，平安度过了这3年的时光。
政策风向突变，人们就像从肖申克监狱放出来的老布，对于身边如此迅速的变化无所适从。但政策放开是综合利弊的结果，并不意味着疫情已经结束。恰恰相反，真正的科学防疫才刚刚开始。
悲观的说，对于我们绝大多数人，最终还是要感染新冠的，我们要做的是把这个时间尽可能往后拖。至少不要踩上地方政策的尾巴，被猛于虎的防疫政策伤到。也不要在第一个高峰期感染，避开医疗资源挤兑的高峰，保护别人也保护自己。
口罩现在还不能摘。对于呼吸道传染病，规范佩戴口罩是最简单有效的防护措施，没有之一。外科口罩和N95口罩可根据不同情况选用，但要注意避免使用带有呼吸阀的口罩，同时远离佩戴这种口罩的人（他们呼出的气体不会被口罩过滤，而是直接从呼吸阀排出）。
人多的地方少去凑热闹，菜市场超市买完东西赶紧走。一是防疫方面，远离传染源。二是安全方面，经历了这三年，整个社会戾气都比较重，难免人群中混入些不法分子干点不法的事情。
常用药还得备上。常用的口服药，感冒药，退热药，抗生素还要备上。例如氨咖黄敏，对乙酰氨基酚，布洛芬，阿莫西林，头孢，阿奇霉素等等，一旦感染可以根据情况服药。
疫苗要接种，打安全有效的疫苗。安全且有效，目前有符合这两项要求的么？“我的防弹衣防不住子弹，但是能防得住炮弹”--就是个笑话。
粮食还得囤。现在是纯粹的摸石头过河，翻车的风险是客观存在的；奥密克戎变种很快，也有可能再杀个回马枪。吃的东西家里面还要备一些，家中有粮心中不慌。
莫恐慌莫盲从。凡事想想为什么，收集信息，独立思考，自己做一下风控。不要人云亦云，被别人牵着鼻子走。脑子是个好东西，就是有些人没有。
这次政策的步子比较大，有点扯住蛋了，一些地方部门和单位还没有跟上节奏。比如某公厕，至今仍要求持有48小时内核酸阴性证明才能拉屎。比如某医院，要求医务人员感染之后继续上班。就现在各科室的密切程度，妥妥的一人阳，一科阳，一楼阳，整个医院羊了个羊--养蛊呢。
最后，致当年的防疫爱好者们，你们可以选择继续居家，不出门，不再与外界交流。也可以考虑把门窗都封死，避免病毒进来

2019.12--2022.12, protected for two years, tossed for a year, with mixed reputations, the curtain has finally come to an end.
Thank you medical workers and grassroots staff. Thank you for your hard work, which has saved most people from the new crown infection and passed these 3 years safely.
The policy direction has changed suddenly, and people are like old cloth released from Shawshank Prison, at a loss for such rapid changes around them. However, policy liberalization is the result of comprehensive advantages and disadvantages, and it does not mean that the epidemic is over. On the contrary, the real scientific epidemic prevention has just begun.
Pessimistically speaking, for the vast majority of us, we will eventually be infected with the new crown. What we have to do is to delay this time as much as possible. At least don't step on the tail of local policies and be hurt by the epidemic prevention policy that is fiercer than a tiger. Don't get infected at the first peak, avoid the peak of medical resources run, protect others and protect yourself.
Masks cannot be removed yet. For respiratory infectious diseases, standard wearing of masks is the simplest and most effective protective measure, not one of them. Surgical masks and N95 masks can be selected according to different situations, but pay attention to avoid using masks with breathing valves, and stay away from people wearing such masks (their exhaled gas will not be filtered by the mask, but directly discharged from the breathing valve) .
Don't go to places with a lot of people to join in the fun, and leave quickly after shopping in the vegetable market and supermarket. One is in terms of epidemic prevention, keep away from the source of infection. The second is security. After these three years, the whole society has become more hostile, and it is inevitable that some criminals will mix in the crowd and do some illegal things.
Commonly used medicines have to be prepared. Commonly used oral medicines, cold medicines, antipyretics, and antibiotics should also be prepared. For example, ampicillin, acetaminophen, ibuprofen, amoxicillin, cephalosporin, azithromycin, etc. Once infected, you can take medicine according to the situation.
Vaccines must be vaccinated, safe and effective vaccines. It is safe and effective. Are there any products that meet these two requirements? "My body armor can't stop bullets, but it can stop shells" -- that's a joke.
Food has to be stockpiled. Now it is purely crossing the river by feeling the stones, and the risk of overturning is an objective existence; the Omicron variant is very fast, and it is also possible to kill the carbine again. I have to prepare some food at home, so I don’t panic when I have food at home.
Don't panic, don't follow blindly. Think about why everything, collect information, think independently, and do your own risk control. Don't follow others and be led by others. Brain is a good thing, but some people don't have it.
The pace of the policy this time is relatively large, and it is a bit of a drag. Some local departments and units have not kept up with the pace. For example, a public toilet still requires a certificate of negative nucleic acid within 48 hours to defecate. For example, a hospital requires medical staff to continue to work after infection. As far as the closeness of each department is concerned, one person is yang, one department is yang, and the first floor is yang. The whole hospital has a sheep-raising Gu.
Finally, to the epidemic prevention enthusiasts back then, you can choose to continue to stay at home, not to go out, and no longer communicate with the outside world. You can also consider sealing the doors and windows to prevent the virus from entering
