Strengthening the on-site handling capacity of health and epidemic prevention workers is an effective means to deal with public health emergencies. In order to minimize the phenomenon of "emphasizing theory and neglecting practice" in the current field epidemic teaching, it’s necessary to integrate virtual simulation technology into the field epidemiology practice teaching system. The teach-ing platform combines virtual scenes with practice teaching. This could guide the students to complete the investigation and control of emergency public health events in the virtual scene, develop students’ skills in dealing with emergency public health events, expand the space for field epidemiology practice teaching, and provide independent learning opportunity for students. Furthermore, it provides a poten-tial solution to the problems of high pollution, high cost and high risk in the training in handling public health emergencies, and has a broad application prospect in the field of preventive medicine education.
