In many areas, when the epidemic was first discovered, it was spread by students because students came into contact with more people in their lives. For example, parents of students may come back from another city one day and bring some viruses to their children. Without nucleic acid, they cannot be detected in time. When students return to school, they will spread these viruses to their classmates, forming a very huge transmission chain. Many people know that the safety of students is very important, so this practice is very helpful for local epidemic prevention and control.
Because many people will not do nucleic acid in time after going to other areas, under such circumstances, it is impossible to monitor whether their bodies are infected in time. After the emergence of such regulations, some parents also need to do nucleic acid during the process of sending their children to school, so under such circumstances, even some parents who come back from other places will not lead to the spread of the epidemic at the stage of sending their children to school. Because in this case, every child needs to do nucleic acid to return to school normally, so the epidemic will not spread to other places. If there is an outbreak, it can be controlled in time and will not lead to the spread of the local epidemic.
In daily life, nucleic acid is a very effective method to prevent and control the epidemic. Therefore, everyone needs to make nucleic acids according to local conditions to avoid infection. This practice is a very responsible phenomenon for students and parents, because under such circumstances, it can bring a very safe living environment to everyone, so there will be no diagnosis.
