This cluster epidemic in middle schools once again sounded the alarm for other schools to prevent and control the epidemic, warning other schools not to relax their mentality of preventing and controlling the epidemic, especially schools should strengthen the tracking and control of students and teachers' traces of epidemic prevention and control. We must adhere to timeliness, openness and accuracy to ensure the health and safety of every student and teacher in the school and the school itself.

The first thing to do is to inquire about the teachers and students of the whole school in time, openly and quickly, and register the flow records of teachers and students. In the daily process of teachers and students going to school or returning to school on holidays, the school should strictly control the admission requirements for each returning teacher and student, inform parents in advance whether the registered students have any records of going out, and require off-campus students to hold nucleic acid certificates within 48 hours before entering the school. If there are off-campus teachers, according to the principle of one-day inspection, they should be tested for three days after entering the school, and at the same time, they need to provide nucleic acid proof within 48 hours before entering the school. The school requires parents to wear masks during the whole process of picking up their children, and parents are not allowed to enter the school to pick up their children.

The second point is to accurately control the flow records of each teacher and student. Teachers and students who have been to high-risk areas or had close contact when returning should report to the school immediately, and report to the school in time the relevant personnel they have contacted and every place they have been. The school will accurately count in place, start a series of disinfection measures, set up centralized nucleic acid sampling points in the school, and quickly and effectively screen personnel. And put the students who are in close contact with each other in a sterile environment, promptly notify the Center for Disease Control and Prevention in the jurisdiction, establish a green rapid transfer channel, promptly and accurately inform the parents of the students, and inform the school of the current epidemic situation, so as to reassure parents and not cause panic among teachers, students and parents of the school. Ensure the health status of the remaining teachers and students in the school, observe the physical condition of the students who have been in close contact, and carry out nucleic acid detection on the remaining teachers and students in the school according to the three-day two-time inspection.
