Objective To understand and master the microbial pollution and disinfection quality of kindergartens and nurses in Hanzhong City and to promote the disease prevention and control of nurseries. Methods From 2003 to 2008, 3390 samples from 39 nurseries in Hanzhong city, including indoor air, personnel ’s surface and indoor objects were collected for microbial contamination testing. Results The air samples were 404 samples and the total bacteria exceeded the standard by 90.84%. The over-standard rates of air bacteria in classrooms and dormitories were 93.69% and 87.88%, respectively. 789 samples were hand-held by nurseries, and the passing rates before and after hand washing were 15.59 %, 88.97%. The passing rates of chef and child before hand washing were all lower. 704 samples were tested before and after disinfection on the surface of the objects, the pass rates were 18.18% and 90.63% respectively. Conclusions Microbiological pollution in kindergartens and nurseries is more serious. It is necessary to raise awareness of the importance of kindergartens and nurses’ hygiene work, to establish a preventive and disinfection work system for health and hygiene of nurseries, to carry out preventive disinfection work on a regular basis, and to improve disease prevention in nurseries. Early warning mechanism to prevent the occurrence and prevalence of infectious diseases in children.
