The goals of this study were to observe the spread of viruses in a hotel setting and to assess the effectiveness of a hygiene intervention in reducing their spread. Selected fomites in one hotel room were inoculated with bacteriophage ϕx-174, and fomites in a conference center within the same hotel were inoculated using bacteriophage MS2. Cleaning of the contaminated room resulted in the spread of viruses to other rooms by the housekeeping staff. Furthermore, viruses were transferred by hotel guests to the conference center and a communal kitchen area. Additionally, conference attendees transferred viruses from the conference center to their hotel rooms and a communal kitchen area. This study demonstrated how viruses can be spread throughout a hotel setting by both housekeepers and guests. A hygiene intervention, which included providing hand hygiene products and facial tissues to the guests and disinfecting solutions with disposable wipes to the housekeeping staff, was successful in reducing the spread of viruses between the hotel guest rooms and conference center. The hygiene intervention resulted in significantly reduced transfer of the ϕx-174 between the contaminated hotel room and other hotel rooms, communal areas, and the conference center (p = 0.02).
本研究的目的是观察病毒在酒店环境中的传播情况，并评估一项卫生干预措施在减少病毒传播方面的有效性。在酒店的一个房间内，选定的污染物表面接种了噬菌体ϕx - 174，而在同一酒店的会议中心，污染物表面接种了噬菌体MS2。对受污染房间的清洁导致病毒被客房服务人员传播到其他房间。此外，病毒被酒店客人传播到会议中心和公共厨房区域。此外，会议参与者将病毒从会议中心传播到他们的酒店房间和公共厨房区域。这项研究证明了病毒是如何通过客房服务人员和客人在整个酒店环境中传播的。一项卫生干预措施，包括向客人提供手部卫生用品和面部纸巾，向客房服务人员提供含一次性擦拭巾的消毒溶液，成功减少了酒店客房和会议中心之间病毒的传播。卫生干预措施使ϕx - 174在受污染的酒店房间与其他酒店房间、公共区域和会议中心之间的传播显著减少（p = 0.02）。
