So it is really necessary to test nucleic acid once every three days. Moreover, we can also see that many first-tier cities and second-tier cities have invested heavily in nucleic acid resources, and many medical staff help people make nucleic acids free of charge in kiosks every day. This is because the flow of people is relatively large, and if you don't do nucleic acid, some corresponding problems may occur. Then we also need to cooperate with such staff to do nucleic acid every day, so as to ensure our own safety.
Moreover, you can monitor your health reasonably, and if you have corresponding problems, report them in time, which will also bring some good examples to yourself and others. Doing nucleic acid can know our health status and let us fully understand what kind of state we are in now, which is a crucial issue for everyone.
Because nucleic acid does happen repeatedly, if we don't monitor our health well, once there is a problem, it will affect many people. We also need to be responsible for ourselves and others. If we go to work without knowing it, or go to some crowded places, there will be some health risks.
