Therefore, it is necessary to open the window every day to ventilate, keep the indoor air circulating, ensure the air fresh, and let the sun shine on the classroom to naturally sterilize and kill viruses.

Therefore, it is necessary to disinfect the children's activity environment with disinfectant every day. Tableware, floor, towels, etc. should be disinfected regularly in strict accordance with the requirements, and quilts used for sleeping should also be cleaned and disinfected on time.

3. Do a good job in the morning check-up. When entering the park every day, the teacher should closely observe the child's mental condition and body temperature, and closely observe the children with fever and cough. If three children have similar situations at the same time, they should be treated in isolation in time, disinfected and reported.

4. Strengthen daily care, try to avoid taking children into crowded places with poor air circulation, properly carry out sports and outdoor activities, improve children's physical fitness, and make nutritional supplements at the same time.
