Some schools require students in middle-risk areas to have a nucleic acid test certificate within 48 hours after unsealing.

The prevention and control of epidemic situation in schools in high-risk areas is the prominent focus of epidemic prevention and control in education system. Especially on the occasion of returning to school, the inter-provincial mobility of teachers and students has increased, and the risk of campus epidemic can not be ignored. Liu, deputy director of the Department of Sports, Health and Arts of the Ministry of Education and a first-class inspector, recently responded to how schools, teachers and students in high-risk areas can do a good job in epidemic prevention and control at the press conference of the joint prevention and control mechanism of the State Council Office. Liu introduced that before the start of school in various places, the Ministry of Education required all schools in various places to always maintain the efficient operation of the epidemic prevention and control leadership system, emergency mechanism and command system, coordinate the implementation of the school start plan and back-to-school measures, coordinate the normal prevention and control and emergency response, and coordinate the realization of personnel health and campus safety. According to reports, the Ministry of Education has made unified arrangements for the prevention and control of schools, teachers and students in high-risk areas. The principle is that schools in medium and high-risk areas will be suspended, and teachers and students in medium and high-risk areas will be suspended from returning to school until the local epidemic situation is obviously improved and the risk level is reduced. Arrange a safe and orderly return to school.
