人类诺如病毒是流行性胃肠炎的主要原因，特别是在半封闭的环境中，如托儿所，疗养院，医院，学校和游轮上。暴发往往伴随着环境表面和常用物品的污染。研究了在保持80%相对湿度的室中，通过百万分之20的大气臭氧对诺如病毒替代物猫杯状病毒和鼠诺如病毒的表面消毒。处理后，在玻璃表面上均未检测到病毒，但从未处理的对照中回收到>5 log感染性病毒。用于净化小型手接触物品的臭氧室可能是控制诺如病毒爆发的重要工具。
Human norovirus is the leading cause of epidemic gastroenteritis, especially in semiclosed settings such as daycares, nursing homes, hospitals, schools and on cruise ships. Outbreaks are often accompanied by contamination of environmental surfaces and commonly handled items. Surface disinfection of norovirus surrogates, feline calicivirus and murine norovirus, by 20 parts per million atmospheric ozone in a chamber maintaining 80% relative humidity was investigated. After treatment, neither virus could be detected on glass surfaces, but >5 log infectious virus was recovered from untreated controls. Ozone chambers used to decontaminate small, hand-contact items could be an important tool for controlling norovirus outbreaks.
