Severe Acute Respiratory Syndrome - Coronavirus - 2 (SARS-CoV-2) is a virus, primarily transmitted through droplets, able to persist on different surfaces and in the air for several hours. During the COVID-19 pandemic, Health Care Workers should be considered a high risk profession. Beside social distancing rules and the proper use of Personal Protective Equipment, sanitization measures and ventilation system disinfection are essential to reduce viral transmission.
This is the first Italian study aiming to assess the magnitude of environmental contamination in a COVID-19 non-Intensive Care Unit.
In addition to ordinary cleaning procedures, surface and air samplings have been performed before and after the application of two different sanitization devices. Samples have been analyzed with Real Time-Polymerase Chain Reaction in order to find viral RNA.
All samples obtained from surfaces and air before and after extra-ordinary sanitization procedures turned out negative for viral detection.
These findings highlight the efficiency of ordinary cleaning procedures in guaranteeing a safer workplace. The adoption of additional sanitization protocols should be considered in order to further reduce environmental viral contamination.
严重急性呼吸系统综合症-冠状病毒-2（SARS-CoV-2）是一种病毒，主要通过飞沫传播，能够在不同表面和空气中存活数小时。在 COVID-19 大流行期间，医护人员应被视为高风险职业。除了保持社交距离和正确使用个人防护设备外，消毒措施和通风系统消毒对于减少病毒传播至关重要。
这是第一项旨在评估 COVID-19 非重症监护病房环境污染程度的意大利研究。
除了常规清洁程序外，还在应用两种不同消毒设备前后对表面和空气进行了采样。使用实时聚合酶链反应对样本进行了分析，以寻找病毒 RNA。
所有在非凡消毒程序前后从表面和空气中获得的样本均未检测到病毒。
这些发现强调了常规清洁程序在保证更安全的工作场所方面的有效性。应考虑采用额外的消毒方案，以进一步减少环境中的病毒污染。
