[0002] At present, although infection prevention and control skill training has integrated various ways and methods such as scenario-based teaching, video-based self-training, and simulation track drilling, it still mainly adopts the traditional teaching and training mode. Students trained by the traditional teaching and training mode have relatively solid theoretical knowledge and operation essentials, but their subjective initiative is not easy to exert, and their comprehensive analysis and problem-solving ability is relatively weak after they are put into actual work, especially in the time-tight, task-urgent, and complex epidemic prevention and control front-line treatment scene. Moreover, medicine is a discipline that emphasizes practice, which not only needs theoretical support, but also needs the accumulation and application of practical experience.

[0003] At present, combined with the actual task requirements of various epidemic prevention and control, it is found that the above teaching and training mode still has shortcomings: ① Infection prevention and control skills need repeated operation practice, and the teaching resources such as teachers, venues, and materials are consumed, the students' practical transformation ability is weak, and it is difficult to quickly master the essentials of skills; ② Infection prevention and control knowledge system integration is difficult, and students' comprehensive analysis and application ability is weak; ③ The first-line treatment scene is difficult to reproduce truly, and there is a high infection risk in field learning. The functions of VR technology such as scene restoration, motion capture, and scene interaction provide new possibilities for us to build high-risk infectious disease treatment practical training.

[0004] At present, the personal protection training of medical students in the medical school of Tokyo University, the teaching of surgical site infection for medical students in the medical school of Copenhagen University, and the teaching of hospital infection in the nursing school of San Sebastian University in Chile all apply virtual simulation technology.
