It is necessary to establish a ledger for returnees, find out the history of teachers, students and their families going out to live, and implement the responsibility for security one by one. Teachers and students who have not returned to school to celebrate should "double report" to the community and units in advance. Teachers and students living in other places in the near future should take the initiative to carry out nucleic acid testing and do health monitoring as required. Teachers and students in centralized isolation should arrange special personnel for health tracking. Before entering the school, the cleaning, security, canteen, infrastructure and other personnel who serve in the school should trace back and analyze the whereabouts of their individuals and family members to ensure safety.

Second, in the aspect of campus closure, we should implement network school management.

All kindergartens in primary and secondary schools are closed in summer. In addition to the 24-hour emergency duty personnel, other personnel are not allowed to enter the campus at will, and students are not allowed to return to school in advance. Those who really need to enter the campus because of work must show their health code and itinerary code, register their real names and take their temperature, and then enter after approval. Schools should stop off-line gathering activities, not open classrooms, gymnasiums and other places on campus, and not organize off-line activities such as campus open days, counseling and answering questions. Continue to intensify the investigation of private kindergartens and off-campus training institutions, and schools that do not have the conditions for running schools and the requirements for prevention and control should be shut down immediately.

Third, in terms of school preparation, closed-loop measures should be implemented.

All schools should do a good job in the preparation of material reserves, personnel control, plan formulation, environmental disinfection, simulation exercises, etc. before the start of school. School leaders should take the lead to stop taking vacations and return to their posts in time. In principle, the teaching and administrative staff shall not leave the school anniversary or the province. Students are not allowed to leave the celebration or go out of the province. Guide teachers and students to pay attention to safety and return to the celebration as soon as possible. 14 organize teachers and students to conduct self-observation and test at home before school starts. The summer vacation of senior three is conducted online, and the offline recovery time is subject to the notice of the Municipal Education Bureau. The military training of Grade One in Senior High School will be suspended, and the new students' registration and the start time of Grade Two in Senior High School will be notified separately.

Fourth, in terms of vaccination, it is necessary to take it.

It is necessary to do a good job of docking with the local health center for disease control and prevention, reasonably arrange the time, venue and process of students' vaccination, and do a good job in on-site organization and service guarantee. It is necessary to establish a "vaccination list for students in school" and a "vaccination taboo list for students in school", mobilize qualified students to take the initiative to vaccinate, and accelerate the construction of immune protection barriers.
