Abstract
The transmission of infectious diseases during hotel stays (e.g., by touching unclean towels or bed linens) has been reported globally. Although the majority of hotels now follow international standards on the housekeeping and laundry processes, the number of hygiene-related problems remains high. In a field study at a high-end hotel in China, we revealed a possible channel of disease transmission between consecutive guests in hotel rooms. In order to prevent the transmission, we designed an innovative hotel guest room housekeeping process. To optimize the labor efficiency, we decomposed the housekeeping process and characterized the service time distribution of each operational step using data collected from hundreds of times of housekeeping. Our pilot test results showed that the new housekeeping process achieves significant improvement in not only hygienic standards but also labor efficiency and service quality (error rate).
