Abstract: Objective　By analyzing the experience in the prevention and control of infectious diseases in schools and summarizing the mechanism of linkage prevention and control of infectious diseases in schools, this paper aims to provide references to promote the realization of the normalization of the prevention and control of infectious diseases in schools.Methods　Phenomenological research methods were used to conduct in-depth interviews with 18 school doctors from primary schools, middle schools and universities in Beijing. After the interviews were transcribed, the data were analyzed by Colaizzi seven-step analysis method and fishbone diagram analysis method.Results　The coded information was categorized and a four-pronged joint prevention and control mechanism of "student-parent-school doctor-school" for infectious diseases in schools was summarized. At the student level, students are trained to have good hygiene habits through health promotion and education, and are actively relieved of their bad emotions when infectious diseases occur. At the parent level, the home-school connection is strengthened so that parents have clear knowledge about infectious diseases and patiently cooperate with the school. At the level of school doctors, the school doctors' role in supervising and coordinating the work of infectious diseases at school is given full play to protect the health of adolescents. At the school level, relevant systems should be established and improved to gradually normalize the prevention and control of infectious diseases.Conclusion　In order to better reduce and prevent the occurrence and development of infectious diseases, schools should establish a four-pronged joint prevention and control mechanism of "student-parent-school doctor-school" in the process of management, and jointly help students to grow up healthily and ensure the health of adolescents through a joint home and school approach.
