The emergence of the coronavirus disease 2019 (COVID-19) pandemic highlighted the importance of disinfection processes in health safety. Textiles and footwear have been identified as vectors for spreading infections. Therefore, their disinfection can be crucial to controlling pathogens' dissemination. The present work aimed to evaluate the effectiveness of a commercial disinfectant aerosolized by an ultrasonic nebulizer closet as an effective method for disinfecting textiles and footwear. The disinfection was evaluated in three steps: suspension tests; nebulization in a 0.08 m closet; nebulization in the upscaled 0.58 m closet. The disinfection process of textiles and footwear was followed by the use of bacteriophages, bacterial spores, and bacterial cells. The disinfection in the 0.58 m closet was efficient for textiles (4 log reduction) when bacteriophage , and were used. The footwear disinfection was achieved (4 log reduction) in the 0.08 m closet for and . Disinfection in an ultrasonic nebulization closet has advantages such as being quick, not wetting, being efficient on porous surfaces, and is performed at room temperature. Ultrasonic nebulization disinfection in a closet proves to be useful in clothing and footwear stores to prevent pathogen transmission by the items' widespread handling.
2019 年冠状病毒病(COVID-19)大流行的出现凸显了消毒过程在卫生安全中的重要性。纺织品和鞋类已被确定为传播感染的载体。因此,对其进行消毒对于控制病原体的传播可能至关重要。本工作旨在评估超声雾化柜雾化的商业消毒剂作为消毒纺织品和鞋类的有效方法的效果。消毒分三步进行:悬浮试验;在 0.08 m 柜中雾化;在放大的 0.58 m 柜中雾化。使用噬菌体、细菌孢子和细菌细胞对纺织品和鞋类的消毒过程进行了跟踪。当使用噬菌体 和 时,0.58 m 柜中的消毒对纺织品有效(减少 4 对数)。当使用 和 时,0.08 m 柜中的鞋类消毒达到(减少 4 对数)。柜内超声雾化消毒具有快速、不润湿、对多孔表面有效且在室温下进行等优点。证明柜内超声雾化消毒在服装和鞋店有用,可以防止物品广泛处理引起的病原体传播。
