Abstract

SARS-CoV-2 spread rapidly, causing millions of deaths across the globe. As a result, demand for medical supplies and personal protective equipment (PPE) surged and supplies dwindled. Separate entirely, hospital-acquired infections have become commonplace and challenging to treat. To explore the potential of novel sterilization techniques, this study evaluated the disinfection efficacy of Fathhome's ozone-based, dry-sanitizing device by dose and time response. Inactivation of human pathogens was tested on non-porous (plastic) surfaces. 95.42–100% inactivation was observed across all types of vegetative microorganisms and 27.36% inactivation of bacterial endospores tested, with no residual ozone detectable after completion. These results strongly support the hypothesis that Fathhome's commercial implementation of gas-based disinfection is suitable for rapid decontamination of a wide variety of pathogens on PPE and other industrially relevant materials.

通过Fathhome的干式消毒装置灭活多种人类病原体:快速、环保的臭氧消毒

SARS-CoV-2迅速传播，在全球造成数百万人死亡。因此，对医疗用品和个人防护装备的需求激增，供应减少。完全独立的医院获得性感染已经变得司空见惯，而且很难治疗。为了探索新型灭菌技术的潜力，本研究通过剂量和时间响应来评估Fathhome的臭氧干式消毒装置的消毒效果。在无孔(塑料)表面上测试了人类病原体的失活。所有类型的营养微生物失活率为95.42-100%，细菌内生孢子失活率为27.36%，完成后未检测到残留臭氧。这些结果有力地支持了一种假设，即Fathhome的商业化气体消毒适用于PPE和其他工业相关材料上各种病原体的快速去污。
