Recently, the epidemic situation in the country has become increasingly stable, and the overall trend of improvement has continued to consolidate. With the opening of schools in various places and the beginning of spring farming in rural areas, will there be a large-scale epidemic in a short time in the future? What prevention and control measures will primary and secondary schools take? How to further improve the epidemic prevention capacity in remote rural areas? Focusing on the hot spots of public concern, the joint prevention and control mechanism of the State Council held a press conference on the 9th to make a centralized response. Wu Zunyou, the chief epidemiologist of the Chinese Center for Disease Control and Prevention, said that China had just experienced a nationwide epidemic of COVID-19 infection, and most people had recovered, while some people were still recovering. The immunity protection of the population nationwide was at a high stage. The surveillance data of COVID-19 in China shows that since January 1, 2023, 39 evolutionary branches have been detected from the entry personnel at all ports of the country, all of which are Omikron variants, mainly BA. 5.2 and BF. 7 and their sub branches. So far, no new variants with significantly increased transmission, pathogenicity and immune escape ability have been detected. Wu Zunyou believes that, generally speaking, COVID-19 has continued to mutate over the past three years, and its infectivity and immune escape ability are increasing, but its pathogenicity is weakening. With the optimization of epidemic prevention and control strategies and measures in China, the COVID-19 epidemic may occur intermittently in some areas, some people and for a period of time in the future, but it is less likely that it will occur again nationwide in a short time. Recently, COVID-19 antibody testing services have been carried out in many places. In this regard, Chen Cao, a researcher from the Institute of Viral Diseases of the Chinese Center for Disease Control and Prevention, said that the purpose of COVID-19 antibody testing is to estimate the level of COVID-19 antibody in the whole population, and to calculate the infection level of the population, so as to provide data support and scientific basis for the adjustment of the national immunization strategy and prevention and control strategy. If there is no risk of epidemic, students generally do not delay returning to school. Liu Peijun, deputy director of the Department of Sports Health and Art Education of the Ministry of Education and a first-level inspector, said that the current situation of the epidemic situation in the country is generally stable, the school epidemic prevention and control policy has been clearly defined, and the school opening preparations are basically in place, and schools across the country can start school as scheduled, normally and safely this spring. "If there is no special situation, the school will not start in advance; if there is no epidemic risk, students will not delay returning to school," Liu Peijun said. Primary and secondary schools around the country have opened one after another. What prevention and control measures will be taken? Liu Peijun said that we should focus on three aspects of work: first, ensure the physical and mental health of students. One week before the start of school and return to school, students are required to carry out daily health self-test at home; After returning to school, health monitoring was carried out for 7 consecutive days. When entering school, teachers and students should measure their body temperature, and teachers and students who find fever and other symptoms should take corresponding measures such as staying in time. We will implement the morning and afternoon inspection systems for primary and secondary schools, the infectious disease epidemic reporting system, and the tracking and registration system for absenteeism due to illness. We will not organize or require teachers and students in the recovery period to participate in intensive activities. The second is to ensure the normal order of the school. Primary and secondary schools are fully prepared for education and teaching. In areas where there is no epidemic, normal offline teaching activities will be carried out after the school starts. According to the actual learning situation of students, the teaching schedule will be reasonably arranged, and the national curriculum plan and curriculum standard will be carefully implemented to ensure education
