The first is to strengthen publicity and education. Schools use blackboard newspapers, campus radio and bulletin boards to publicize the common sense of influenza prevention and control, and enhance the awareness of disease prevention and resistance of teachers and students. Second, insist on disinfection and sterilization. The school disinfects classrooms, offices, function rooms, corridors, toilets and other public places every day, and each class also cooperates with the method of cooking vinegar to ensure the fresh indoor air and prevent the spread of cold viruses. The third is to clean the environment and do a good job in hygiene. At ordinary times, each class should do a good job of sanitation and cleaning. The teacher urges every student to pay attention to personal hygiene, change clothes and wash and dress frequently. At the same time, each class opens the window in time every day to ensure air circulation. Fourth, do a good job of morning inspection and report. The head teacher should do a good job in the morning check-up and registration of students every day. Once students are found to have a cold epidemic, they should report to the clinic in time and call their parents to prevent, find and treat them early. Fifth, scientifically and reasonably distribute students' recipes, and formulate nutritious meals suitable for students in winter canteens to improve students' own immunity and enhance their disease resistance.
