Based on the epidemic situation in COVID-19 this year, this paper talks about how to prevent and care for children's common infectious diseases.

Do a good job in the prevention and health care of children's common infectious diseases, and pay attention to the following points:

1. Wash your hands frequently. Teaching children to use the seven-step washing method and wash their hands frequently can effectively reduce the breeding of viruses and bacteria.

2. More ventilation. The classroom environment is relatively closed, so it can be ventilated more and increase air circulation.

3. Kill people in time. Do preventive disinfection after school or before school every day to prevent viruses.
