Medical reasons for the low rate of hand-qualified minority medical disinfection and lack of knowledge about their poor quality. The survey asked 96 medical personnel to disinfect knowledge, only 59 people answered correctly. Currently, there are still a small number of hospitals did not monitor ultraviolet intensity, can not do regular monitoring and timely replacement of failed lamps light intensity, resulting in the low passing rate ultraviolet lamp.
