Objective: To understand the health status of operating cafes in Jiangning District, Nanjing, and to provide a reference for health management. Methods: Ten internet cafes were surveyed in Nanjing Jiangning District. The indoor noise, surface illumination, room temperature, relative humidity and the chemical indexes of CO, CO2 and formaldehyde, the total number of bacteria in the air, the total number of bacteria in the keyboard and mouse and the coliform bacteria . Results: The qualified rate of total bacteria in air, CO, formaldehyde and air was higher, which were 100%, 96%, 94% and 92% respectively. The qualified rate of noise, tabletop illuminance, relative humidity and CO2 content were lower, 72%, 66% and 60%, respectively. The total number of bacteria in the surface bacteria was 191 / part, and the positive rate of coliform bacteria was 12%. Conclusion: There are some problems in Jiangning District operating cyber cafe, such as noise, low illumination and relative humidity, high air CO2 content and more bacteria in the keyboard and mouse. Therefore, it is necessary to strengthen health management.
